A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

What is a Literature Review?
A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field.
A literature review should:
- Provide a comprehensive and updated review of the literature;
- Explain why this review has taken place;
- Articulate a position or hypothesis;
- Acknowledge and account for conflicting and corroborating points of view
From S age Research Methods
Purpose of a Literature Review
A literature review can be written as an introduction to a study to:
- Demonstrate how a study fills a gap in research
- Compare a study with other research that's been done
Or it can be a separate work (a research article on its own) which:
- Organizes or describes a topic
- Describes variables within a particular issue/problem
Limitations of a Literature Review
Some of the limitations of a literature review are:
- It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
- It may be too focused. Some niche studies may miss the bigger picture.
- It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
- It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .
There are five key steps to writing a literature review:
- Search for relevant literature
- Evaluate sources
- Identify themes, debates, and gaps
- Outline the structure
- Write your literature review
A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:
- Demonstrate your familiarity with the topic and its scholarly context
- Develop a theoretical framework and methodology for your research
- Position your work in relation to other researchers and theorists
- Show how your research addresses a gap or contributes to a debate
- Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.
Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .
If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .
Make a list of keywords
Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.
- Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
- Body image, self-perception, self-esteem, mental health
- Generation Z, teenagers, adolescents, youth
Search for relevant sources
Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:
- Your university’s library catalogue
- Google Scholar
- Project Muse (humanities and social sciences)
- Medline (life sciences and biomedicine)
- EconLit (economics)
- Inspec (physics, engineering and computer science)
You can also use boolean operators to help narrow down your search.
Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.
You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.
For each publication, ask yourself:
- What question or problem is the author addressing?
- What are the key concepts and how are they defined?
- What are the key theories, models, and methods?
- Does the research use established frameworks or take an innovative approach?
- What are the results and conclusions of the study?
- How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
- What are the strengths and weaknesses of the research?
Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.
You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.
Take notes and cite your sources
As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.
It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.
Receive feedback on language, structure, and formatting
Professional editors proofread and edit your paper by focusing on:
- Academic style
- Vague sentences
- Style consistency
See an example
![research literature def research literature def](https://www.scribbr.com/wp-content/uploads/2018/01/dissertation-proofreading-service.png)
To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:
- Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
- Themes: what questions or concepts recur across the literature?
- Debates, conflicts and contradictions: where do sources disagree?
- Pivotal publications: are there any influential theories or studies that changed the direction of the field?
- Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?
This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.
- Most research has focused on young women.
- There is an increasing interest in the visual aspects of social media.
- But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.
There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).
Chronological
The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.
Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.
If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.
For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.
Methodological
If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:
- Look at what results have emerged in qualitative versus quantitative research
- Discuss how the topic has been approached by empirical versus theoretical scholarship
- Divide the literature into sociological, historical, and cultural sources
Theoretical
A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.
You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.
Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.
The introduction should clearly establish the focus and purpose of the literature review.
Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.
As you write, you can follow these tips:
- Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
- Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
- Critically evaluate: mention the strengths and weaknesses of your sources
- Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts
In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .
An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

What's a Literature Review?
A literature review (or "lit review," for short) is an in-depth critical analysis of published scholarly research related to a specific topic. Published scholarly research (aka, "the literature") may include journal articles, books, book chapters, dissertations and thesis, or conference proceedings.
A solid lit review must:
- be organized around and related directly to the thesis or research question you're developing
- synthesize results into a summary of what is and is not known
- identify areas of controversy in the literature
- formulate questions that need further research

What are Literature Reviews?
So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D. The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.
Goals of Literature Reviews
What are the goals of creating a Literature Review? A literature could be written to accomplish different aims:
- To develop a theory or evaluate an existing theory
- To summarize the historical or existing state of a research topic
- Identify a problem in a field of research
Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews . Review of General Psychology , 1 (3), 311-320.
What kinds of sources require a Literature Review?
- A research paper assigned in a course
- A thesis or dissertation
- A grant proposal
- An article intended for publication in a journal
All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.
Types of Literature Reviews
What kinds of literature reviews are written?
Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.
- Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework: 10.1177/08948453211037398
Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.
- Example : The effect of leave policies on increasing fertility: a systematic review: 10.1057/s41599-022-01270-w
Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.
- Example : Employment Instability and Fertility in Europe: A Meta-Analysis: 10.1215/00703370-9164737
Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts . Journal of Advanced Nursing , 53 (3), 311-318.

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .
If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.
Make a list of keywords
Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.
- Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
- Body image, self-perception, self-esteem, mental health
- Generation Z, teenagers, adolescents, youth
Search for relevant sources
Use your keywords to begin searching for sources. Some databases to search for journals and articles include:
- Your university’s library catalogue
- Google Scholar
- Project Muse (humanities and social sciences)
- Medline (life sciences and biomedicine)
- EconLit (economics)
- Inspec (physics, engineering and computer science)
You can use boolean operators to help narrow down your search:
Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.
To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.
You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.
For each publication, ask yourself:
- What question or problem is the author addressing?
- What are the key concepts and how are they defined?
- What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
- What are the results and conclusions of the study?
- How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
- How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
- What are the strengths and weaknesses of the research?
Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.
You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.
The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).
Remember that you can use our template to summarise and evaluate sources you’re thinking about using!
Take notes and cite your sources
As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.
It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.
You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:
- Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
- Themes: what questions or concepts recur across the literature?
- Debates, conflicts and contradictions: where do sources disagree?
- Pivotal publications: are there any influential theories or studies that changed the direction of the field?
- Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?
This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.
- Most research has focused on young women.
- There is an increasing interest in the visual aspects of social media.
- But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.
There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.
Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).
Chronological
The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.
Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.
If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.
For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.
Methodological
If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:
- Look at what results have emerged in qualitative versus quantitative research
- Discuss how the topic has been approached by empirical versus theoretical scholarship
- Divide the literature into sociological, historical, and cultural sources
Theoretical
A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.
You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.
Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.
The introduction should clearly establish the focus and purpose of the literature review.
If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).
Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.
As you write, make sure to follow these tips:
- Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
- Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
- Critically evaluate: mention the strengths and weaknesses of your sources.
- Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.
In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.
If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.
A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a dissertation , thesis, research paper , or proposal .
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarise yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
The literature review usually comes near the beginning of your dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

- Types of Literature Reviews
- Literature Reviews vs. Systematic Reviews
- Systematic vs. Meta-Analysis
Literature Review is a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.
Also, we can define a literature review as the collected body of scholarly works related to a topic:
- Summarizes and analyzes previous research relevant to a topic
- Includes scholarly books and articles published in academic journals
- Can be an specific scholarly paper or a section in a research paper
The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic
- Help gather ideas or information
- Keep up to date in current trends and findings
- Help develop new questions
A literature review is important because it:
- Explains the background of research on a topic.
- Demonstrates why a topic is significant to a subject area.
- Helps focus your own research questions or problems
- Discovers relationships between research studies/ideas.
- Suggests unexplored ideas or populations
- Identifies major themes, concepts, and researchers on a topic.
- Tests assumptions; may help counter preconceived ideas and remove unconscious bias.
- Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches.
- Indicates potential directions for future research.
All content in this section is from Literature Review Research from Old Dominion University
Keep in mind the following, a literature review is NOT:
Not an essay
Not an annotated bibliography in which you summarize each article that you have reviewed. A literature review goes beyond basic summarizing to focus on the critical analysis of the reviewed works and their relationship to your research question.
Not a research paper where you select resources to support one side of an issue versus another. A lit review should explain and consider all sides of an argument in order to avoid bias, and areas of agreement and disagreement should be highlighted.
A literature review serves several purposes. For example, it
- provides thorough knowledge of previous studies; introduces seminal works.
- helps focus one’s own research topic.
- identifies a conceptual framework for one’s own research questions or problems; indicates potential directions for future research.
- suggests previously unused or underused methodologies, designs, quantitative and qualitative strategies.
- identifies gaps in previous studies; identifies flawed methodologies and/or theoretical approaches; avoids replication of mistakes.
- helps the researcher avoid repetition of earlier research.
- suggests unexplored populations.
- determines whether past studies agree or disagree; identifies controversy in the literature.
- tests assumptions; may help counter preconceived ideas and remove unconscious bias.
As Kennedy (2007) notes*, it is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the original studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field. In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.
Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are several approaches to how they can be done, depending upon the type of analysis underpinning your study. Listed below are definitions of types of literature reviews:
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to to make summary claims of the sort found in systematic reviews.
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.
Historical Review Few things rest in isolation from historical precedent. Historical reviews are focused on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels (i.e. those of theory, substantive fields, research approaches and data collection and analysis techniques), enables researchers to draw on a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection and data analysis, and helps highlight many ethical issues which we should be aware of and consider as we go through our study.
Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyse data from the studies that are included in the review. Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?"
Theoretical Review The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review help establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

What's in the name? The difference between a Systematic Review and a Literature Review, and why it matters . By Lynn Kysh from University of Southern California
Systematic review or meta-analysis?
A systematic review answers a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria.
A meta-analysis is the use of statistical methods to summarize the results of these studies.
Systematic reviews, just like other research articles, can be of varying quality. They are a significant piece of work (the Centre for Reviews and Dissemination at York estimates that a team will take 9-24 months), and to be useful to other researchers and practitioners they should have:
- clearly stated objectives with pre-defined eligibility criteria for studies
- explicit, reproducible methodology
- a systematic search that attempts to identify all studies
- assessment of the validity of the findings of the included studies (e.g. risk of bias)
- systematic presentation, and synthesis, of the characteristics and findings of the included studies
Not all systematic reviews contain meta-analysis.
Meta-analysis is the use of statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects of health care than those derived from the individual studies included within a review. More information on meta-analyses can be found in Cochrane Handbook, Chapter 9 .
A meta-analysis goes beyond critique and integration and conducts secondary statistical analysis on the outcomes of similar studies. It is a systematic review that uses quantitative methods to synthesize and summarize the results.
An advantage of a meta-analysis is the ability to be completely objective in evaluating research findings. Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted. In that case, an integrative review is an appropriate strategy.

Introduction to Literature Reviews
Introduction.
- Step One: Define
- Step Two: Research
- Step Three: Write
- Suggested Readings
A literature review is a written work that :
- Compiles significant research published on a topic by accredited scholars and researchers;
- Surveys scholarly articles, books, dissertations, conference proceedings, and other sources;
- Examines contrasting perspectives, theoretical approaches, methodologies, findings, results, conclusions.
- Reviews critically, analyzes, and synthesizes existing research on a topic; and,
- Performs a thorough “re” view, “overview”, or “look again” of past and current works on a subject, issue, or theory.
From these analyses, the writer then offers an overview of the current status of a particular area of knowledge from both a practical and theoretical perspective.
Literature reviews are important because they are usually a required step in a thesis proposal (Master's or PhD). The proposal will not be well-supported without a literature review. Also, literature reviews are important because they help you learn important authors and ideas in your field. This is useful for your coursework and your writing. Knowing key authors also helps you become acquainted with other researchers in your field.
Look at this diagram and imagine that your research is the "something new." This shows how your research should relate to major works and other sources.

What is a literature review?
A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.
![research literature def](https://pp-blog.paperpal.com/wp-content/uploads/2023/12/image.png)
What is the purpose of literature review?
A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2
1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge.
2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research.
4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered.
5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research.
6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature.
Literature review example
Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic.
Literature Review on Climate Change Impacts on Biodiversity:
Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies:
a. Habitat Loss and Species Extinction:
Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements.
b. Range Shifts and Phenological Changes:
Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources.
c. Ocean Acidification and Coral Reefs:
The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems.
d. Adaptive Strategies and Conservation Efforts:
Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review
Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1
Choose a Topic and Define the Research Question:
- Select a topic that is relevant to your field of study.
- Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore?
Decide on the Scope of Your Review:
- Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview?
- Consider the geographical scope. Is your review global, or are you focusing on a specific region?
- Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude?
Select Databases for Searches:
- Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar.
- Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic.
Conduct Searches and Keep Track:
- Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques.
- Record and document your search strategy for transparency and replicability.
- Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references.
Review the Literature:
- Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies.
- Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research.
- Summarize key findings and arguments from each source. Compare and contrast different perspectives.
- Identify areas where there is a consensus in the literature and where there are conflicting opinions.
- Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research?
Organize and Write Your Literature Review:
- Literature review outline should be based on themes, chronological order, or methodological approaches.
- Write a clear and coherent narrative that synthesizes the information gathered.
- Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.).
- Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.
Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.
Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic.
Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods.
Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers. Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved. Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic. Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings. Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject. It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.
The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review: Introduction: Provide an overview of the topic. Define the scope and purpose of the literature review. State the research question or objective. Body: Organize the literature by themes, concepts, or chronology. Critically analyze and evaluate each source. Discuss the strengths and weaknesses of the studies. Highlight any methodological limitations or biases. Identify patterns, connections, or contradictions in the existing research. Conclusion: Summarize the key points discussed in the literature review. Highlight the research gap. Address the research question or objective stated in the introduction. Highlight the contributions of the review and suggest directions for future research.
Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:
Annotated Bibliography | Literature Review | |
Purpose | List of citations of books, articles, and other sources with a brief description (annotation) of each source. | Comprehensive and critical analysis of existing literature on a specific topic. |
Focus | Summary and evaluation of each source, including its relevance, methodology, and key findings. | Provides an overview of the current state of knowledge on a particular subject and identifies gaps, trends, and patterns in existing literature. |
Structure | Each citation is followed by a concise paragraph (annotation) that describes the source’s content, methodology, and its contribution to the topic. | The literature review is organized thematically or chronologically and involves a synthesis of the findings from different sources to build a narrative or argument. |
Length | Typically 100-200 words | Length of literature review ranges from a few pages to several chapters |
Independence | Each source is treated separately, with less emphasis on synthesizing the information across sources. | The writer synthesizes information from multiple sources to present a cohesive overview of the topic. |

A literature review is a discussion of the literature (aka. the "research" or "scholarship") surrounding a certain topic. A good literature review doesn't simply summarize the existing material, but provides thoughtful synthesis and analysis. The purpose of a literature review is to orient your own work within an existing body of knowledge. A literature review may be written as a standalone piece or be included in a larger body of work.
You can read more about literature reviews, what they entail, and how to write one, using the resources below.

Organizational Tools for Literature Reviews
One of the most daunting aspects of writing a literature review is organizing your research. There are a variety of strategies that you can use to help you in this task. We've highlighted just a few ways writers keep track of all that information! You can use a combination of these tools or come up with your own organizational process. The key is choosing something that works with your own learning style.
Citation Managers
Citation managers are great tools, in general, for organizing research, but can be especially helpful when writing a literature review. You can keep all of your research in one place, take notes, and organize your materials into different folders or categories. Read more about citations managers here:
- Manage Citations & Sources
Concept Mapping
Some writers use concept mapping (sometimes called flow or bubble charts or "mind maps") to help them visualize the ways in which the research they found connects.
![research literature def](https://libapps.s3.amazonaws.com/customers/7633/images/Mind_map.jpg)
There is no right or wrong way to make a concept map. There are a variety of online tools that can help you create a concept map or you can simply put pen to paper. To read more about concept mapping, take a look at the following help guides:

A literature review is a critical analysis of the literature related to your research topic. It evaluates and critiques the literature to establish a theoretical framework for your research topic and/or identify a gap in the existing research that your research will address.
A literature review is not a summary of the literature. You need to engage deeply and critically with the literature. Your literature review should show your understanding of the literature related to your research topic and lead to presenting a rationale for your research.
A literature review focuses on:
- the context of the topic
- key concepts, ideas, theories and methodologies
- key researchers, texts and seminal works
- major issues and debates
- identifying conflicting evidence
- the main questions that have been asked around the topic
- the organisation of knowledge on the topic
- definitions, particularly those that are contested
- showing how your research will advance scholarly knowledge (generally referred to as identifying the ‘gap’).
This module will guide you through the functions of a literature review; the typical process of conducting a literature review (including searching for literature and taking notes); structuring your literature review within your thesis and organising its internal ideas; and styling the language of your literature review.
The purposes of a literature review
A literature review serves two main purposes:
1) To show awareness of the present state of knowledge in a particular field, including:
- seminal authors
- the main empirical research
- theoretical positions
- controversies
- breakthroughs as well as links to other related areas of knowledge.
2) To provide a foundation for the author’s research. To do that, the literature review needs to:
- help the researcher define a hypothesis or a research question, and how answering the question will contribute to the body of knowledge;
- provide a rationale for investigating the problem and the selected methodology;
- provide a particular theoretical lens, support the argument, or identify gaps.

What Is A Literature Review?
A plain-language explainer (with examples).
By: Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)
If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.
Literature Review 101
- What (exactly) is a literature review
- What’s the purpose of the literature review chapter
- How to find high-quality resources
- How to structure your literature review chapter
- Example of an actual literature review
What is a literature review?
The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of reviewing the literature – i.e. sourcing and reading through the existing research relating to your research topic. The second is the actual chapter that you write up in your dissertation, thesis or research project. Let’s look at each of them:
Reviewing the literature
The first step of any literature review is to hunt down and read through the existing research that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then summarise and catalogue these for easy reference when you write up your literature review chapter.
The literature review chapter
The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an overview of the key literature that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an integrated review of the state of knowledge around your research topic.
![what-is-lit-review Starting point for the literature review](https://gradcoach.com/wp-content/uploads/what-is-lit-review.png)
What’s the purpose of a literature review?
The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:
Purpose #1 – Demonstrate your topic knowledge
The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be more than just a summary of who said what – it needs to integrate the existing research to show how it all fits together and what’s missing (which leads us to purpose #2, next).
Purpose #2 – Reveal the research gap that you’ll fill
The second function of the literature review chapter is to show what’s currently missing from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.
Purpose #3 – Lay the foundation for your conceptual framework
The third function of the literature review is to form the basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review.
For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut!
So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework.
Purpose #4 – To inform your methodology
The fourth function of the literature review is to inform the choice of methodology for your own research. As we’ve discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.
So, when you’re reviewing the literature, you’ll need to pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales.

How do I find articles for my literature review?
Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is built on credible research .
We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the most popular pieces of research are in your field.
One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites.
Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to ResearchGate , which is another great source for existing research.
Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer.
Need a helping hand?
How should I structure my literature review?
Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.
You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.
In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .
Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.
![Blog post images (3) A good literature review should synthesise the existing research in relation to the research aims, not simply summarise it.](https://gradcoach.com/wp-content/uploads/Blog-post-images-3.png)

A literature review surveys prior research published in books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.
Fink, Arlene. Conducting Research Literature Reviews: From the Internet to Paper . Fourth edition. Thousand Oaks, CA: SAGE, 2014.
Importance of a Good Literature Review
A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:
- Give a new interpretation of old material or combine new with old interpretations,
- Trace the intellectual progression of the field, including major debates,
- Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
- Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.
Given this, the purpose of a literature review is to:
- Place each work in the context of its contribution to understanding the research problem being studied.
- Describe the relationship of each work to the others under consideration.
- Identify new ways to interpret prior research.
- Reveal any gaps that exist in the literature.
- Resolve conflicts amongst seemingly contradictory previous studies.
- Identify areas of prior scholarship to prevent duplication of effort.
- Point the way in fulfilling a need for additional research.
- Locate your own research within the context of existing literature [very important].

Types of Literature Reviews
It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.
In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.
Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.
Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.
Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.
NOTE: Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style
I. Thinking About Your Literature Review
The structure of a literature review should include the following in support of understanding the research problem :
- An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
- Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
- An explanation of how each work is similar to and how it varies from the others,
- Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.
The critical evaluation of each work should consider :
- Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
- Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
- Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
- Persuasiveness -- which of the author's theses are most convincing or least convincing?
- Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?
II. Development of the Literature Review
Four Basic Stages of Writing 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.
Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. Roughly how many sources would be appropriate to include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5. Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.
III. Ways to Organize Your Literature Review
Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.
Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.
Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:
- Current Situation : Information necessary to understand the current topic or focus of the literature review.
- Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
- History : The chronological progression of the field, the research literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
- Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed [i.e., scholarly] sources.
- Standards : Description of the way in which you present your information.
- Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?
IV. Writing Your Literature Review
Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.
Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.
V. Common Mistakes to Avoid
These are the most common mistakes made in reviewing social science research literature.
- Sources in your literature review do not clearly relate to the research problem;
- You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
- Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
- Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
- Does not describe the search procedures that were used in identifying the literature to review;
- Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
- Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip
Break Out of Your Disciplinary Box!
Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.
Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.
Another Writing Tip
Don't Just Review for Content!
While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:
- How are they organizing their ideas?
- What methods have they used to study the problem?
- What theories have been used to explain, predict, or understand their research problem?
- What sources have they cited to support their conclusions?
- How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?
When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.
Hart, Chris. Doing a Literature Review: Releasing the Social Science Research Imagination . Thousand Oaks, CA: Sage Publications, 1 998.
Yet Another Writing Tip
When Do I Know I Can Stop Looking and Move On?
Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:
- Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research? Does it forge a new path? Or, does is merely add more of the same thing being said?
- Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
- Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

What is a literature review?
The purpose of a literature review, how to write a literature review, the format of a literature review, general formatting rules, the length of a literature review, literature review examples, frequently asked questions about literature reviews, related articles.
A literature review is an assessment of the sources in a chosen topic of research.
In a literature review, you’re expected to report on the existing scholarly conversation, without adding new contributions.
If you are currently writing one, you've come to the right place. In the following paragraphs, we will explain:
- the objective of a literature review
- how to write a literature review
- the basic format of a literature review
Tip: It’s not always mandatory to add a literature review in a paper. Theses and dissertations often include them, whereas research papers may not. Make sure to consult with your instructor for exact requirements.
The four main objectives of a literature review are:
- Studying the references of your research area
- Summarizing the main arguments
- Identifying current gaps, stances, and issues
- Presenting all of the above in a text
Ultimately, the main goal of a literature review is to provide the researcher with sufficient knowledge about the topic in question so that they can eventually make an intervention.
The format of a literature review is fairly standard. It includes an:
- introduction that briefly introduces the main topic
- body that includes the main discussion of the key arguments
- conclusion that highlights the gaps and issues of the literature
➡️ Take a look at our guide on how to write a literature review to learn more about how to structure a literature review.
First of all, a literature review should have its own labeled section. You should indicate clearly in the table of contents where the literature can be found, and you should label this section as “Literature Review.”
➡️ For more information on writing a thesis, visit our guide on how to structure a thesis .
There is no set amount of words for a literature review, so the length depends on the research. If you are working with a large amount of sources, it will be long. If your paper does not depend entirely on references, it will be short.
Take a look at these three theses featuring great literature reviews:
- School-Based Speech-Language Pathologist's Perceptions of Sensory Food Aversions in Children [ PDF , see page 20]
- Who's Writing What We Read: Authorship in Criminological Research [ PDF , see page 4]
- A Phenomenological Study of the Lived Experience of Online Instructors of Theological Reflection at Christian Institutions Accredited by the Association of Theological Schools [ PDF , see page 56]
Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.
There is no set amount of words for a literature review, so the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.
No. A literature review should have its own independent section. You should indicate clearly in the table of contents where the literature review can be found, and label this section as “Literature Review.”
The main goal of a literature review is to provide the researcher with sufficient knowledge about the topic in question so that they can eventually make an intervention.

Chapter 2: Getting Started in Research
Reviewing the Research Literature
Learning Objectives
- Define the research literature in psychology and give examples of sources that are part of the research literature and sources that are not.
- Describe and use several methods for finding previous research on a particular research idea or question.
Reviewing the research literature means finding, reading, and summarizing the published research relevant to your question. An empirical research report written in American Psychological Association (APA) style always includes a written literature review, but it is important to review the literature early in the research process for several reasons.
- It can help you turn a research idea into an interesting research question.
- It can tell you if a research question has already been answered.
- It can help you evaluate the interestingness of a research question.
- It can give you ideas for how to conduct your own study.
- It can tell you how your study fits into the research literature.
What Is the Research Literature?
The research literature in any field is all the published research in that field. The research literature in psychology is enormous—including millions of scholarly articles and books dating to the beginning of the field—and it continues to grow. Although its boundaries are somewhat fuzzy, the research literature definitely does not include self-help and other pop psychology books, dictionary and encyclopedia entries, websites, and similar sources that are intended mainly for the general public. These are considered unreliable because they are not reviewed by other researchers and are often based on little more than common sense or personal experience. Wikipedia contains much valuable information, but the fact that its authors are anonymous and may not have any formal training or expertise in that subject area, and its content continually changes makes it unsuitable as a basis of sound scientific research. For our purposes, it helps to define the research literature as consisting almost entirely of two types of sources: articles in professional journals, and scholarly books in psychology and related fields.
Professional Journals
Professional journals are periodicals that publish original research articles. There are thousands of professional journals that publish research in psychology and related fields. They are usually published monthly or quarterly in individual issues, each of which contains several articles. The issues are organized into volumes, which usually consist of all the issues for a calendar year. Some journals are published in hard copy only, others in both hard copy and electronic form, and still others in electronic form only.
Most articles in professional journals are one of two basic types: empirical research reports and review articles. Empirical research reports describe one or more new empirical studies conducted by the authors. They introduce a research question, explain why it is interesting, review previous research, describe their method and results, and draw their conclusions. Review articles summarize previously published research on a topic and usually present new ways to organize or explain the results. When a review article is devoted primarily to presenting a new theory, it is often referred to as a theoretical article .
![research literature def Figure 2.6 Small Sample of the Thousands of Professional Journals That Publish Research in Psychology and Related Fields](https://opentextbc.ca/researchmethods/wp-content/uploads/sites/37/2019/08/2.5.png)
Most professional journals in psychology undergo a process of double-blind peer review . Researchers who want to publish their work in the journal submit a manuscript to the editor—who is generally an established researcher too—who in turn sends it to two or three experts on the topic. Each reviewer reads the manuscript, writes a critical but constructive review, and sends the review back to the editor along with his or her recommendations. The editor then decides whether to accept the article for publication, ask the authors to make changes and resubmit it for further consideration, or reject it outright. In any case, the editor forwards the reviewers’ written comments to the researchers so that they can revise their manuscript accordingly. This entire process is double-blind, as the reviewers do not know the identity of the researcher(s), and vice versa. Double-blind peer review is helpful because it ensures that the work meets basic standards of the field before it can enter the research literature. However, in order to increase transparency and accountability some newer open access journals (e.g., Frontiers in Psychology) utilize an open peer review process wherein the identities of the reviewers (which remain concealed during the peer review process) are published alongside the journal article.
Scholarly Books
Scholarly books are books written by researchers and practitioners mainly for use by other researchers and practitioners. A monograph is written by a single author or a small group of authors and usually gives a coherent presentation of a topic much like an extended review article. Edited volumes have an editor or a small group of editors who recruit many authors to write separate chapters on different aspects of the same topic. Although edited volumes can also give a coherent presentation of the topic, it is not unusual for each chapter to take a different perspective or even for the authors of different chapters to openly disagree with each other. In general, scholarly books undergo a peer review process similar to that used by professional journals.
Literature Search Strategies
Using psycinfo and other databases.
The primary method used to search the research literature involves using one or more electronic databases. These include Academic Search Premier, JSTOR, and ProQuest for all academic disciplines, ERIC for education, and PubMed for medicine and related fields. The most important for our purposes, however, is PsycINFO, which is produced by the APA. PsycINFO is so comprehensive—covering thousands of professional journals and scholarly books going back more than 100 years—that for most purposes its content is synonymous with the research literature in psychology. Like most such databases, PsycINFO is usually available through your university library.
PsycINFO consists of individual records for each article, book chapter, or book in the database. Each record includes basic publication information, an abstract or summary of the work (like the one presented at the start of this chapter), and a list of other works cited by that work. A computer interface allows entering one or more search terms and returns any records that contain those search terms. (These interfaces are provided by different vendors and therefore can look somewhat different depending on the library you use.) Each record also contains lists of keywords that describe the content of the work and also a list of index terms. The index terms are especially helpful because they are standardized. Research on differences between women and men, for example, is always indexed under “Human Sex Differences.” Research on notetaking is always indexed under the term “Learning Strategies.” If you do not know the appropriate index terms, PsycINFO includes a thesaurus that can help you find them.
Given that there are nearly four million records in PsycINFO, you may have to try a variety of search terms in different combinations and at different levels of specificity before you find what you are looking for. Imagine, for example, that you are interested in the question of whether women and men differ in terms of their ability to recall experiences from when they were very young. If you were to enter “memory for early experiences” as your search term, PsycINFO would return only six records, most of which are not particularly relevant to your question. However, if you were to enter the search term “memory,” it would return 149,777 records—far too many to look through individually. This is where the thesaurus helps. Entering “memory” into the thesaurus provides several more specific index terms—one of which is “early memories.” While searching for “early memories” among the index terms returns 1,446 records—still too many too look through individually—combining it with “human sex differences” as a second search term returns 37 articles, many of which are highly relevant to the topic.
![research literature def QR code that links to PsycINFO video](https://opentextbc.ca/researchmethods/wp-content/uploads/sites/37/2019/08/qrcode.31716515-150x150.png)
Depending on the vendor that provides the interface to PsycINFO, you may be able to save, print, or e-mail the relevant PsycINFO records. The records might even contain links to full-text copies of the works themselves. (PsycARTICLES is a database that provides full-text access to articles in all journals published by the APA.) If not, and you want a copy of the work, you will have to find out if your library carries the journal or has the book and the hard copy on the library shelves. Be sure to ask a librarian if you need help.
Using Other Search Techniques
![research literature def QR code that links to Google Scholar video](https://opentextbc.ca/researchmethods/wp-content/uploads/sites/37/2019/08/qrcode.31716521-150x150.png)
In addition to entering search terms into PsycINFO and other databases, there are several other techniques you can use to search the research literature. First, if you have one good article or book chapter on your topic—a recent review article is best—you can look through the reference list of that article for other relevant articles, books, and book chapters. In fact, you should do this with any relevant article or book chapter you find. You can also start with a classic article or book chapter on your topic, find its record in PsycINFO (by entering the author’s name or article’s title as a search term), and link from there to a list of other works in PsycINFO that cite that classic article. This works because other researchers working on your topic are likely to be aware of the classic article and cite it in their own work. You can also do a general Internet search using search terms related to your topic or the name of a researcher who conducts research on your topic. This might lead you directly to works that are part of the research literature (e.g., articles in open-access journals or posted on researchers’ own websites). The search engine Google Scholar is especially useful for this purpose. A general Internet search might also lead you to websites that are not part of the research literature but might provide references to works that are. Finally, you can talk to people (e.g., your instructor or other faculty members in psychology) who know something about your topic and can suggest relevant articles and book chapters.
What to Search For
When you do a literature review, you need to be selective. Not every article, book chapter, and book that relates to your research idea or question will be worth obtaining, reading, and integrating into your review. Instead, you want to focus on sources that help you do four basic things: (a) refine your research question, (b) identify appropriate research methods, (c) place your research in the context of previous research, and (d) write an effective research report. Several basic principles can help you find the most useful sources.
First, it is best to focus on recent research, keeping in mind that what counts as recent depends on the topic. For newer topics that are actively being studied, “recent” might mean published in the past year or two. For older topics that are receiving less attention right now, “recent” might mean within the past 10 years. You will get a feel for what counts as recent for your topic when you start your literature search. A good general rule, however, is to start with sources published in the past five years. The main exception to this rule would be classic articles that turn up in the reference list of nearly every other source. If other researchers think that this work is important, even though it is old, then by all means you should include it in your review.
Second, you should look for review articles on your topic because they will provide a useful overview of it—often discussing important definitions, results, theories, trends, and controversies—giving you a good sense of where your own research fits into the literature. You should also look for empirical research reports addressing your question or similar questions, which can give you ideas about how to operationally define your variables and collect your data. As a general rule, it is good to use methods that others have already used successfully unless you have good reasons not to. Finally, you should look for sources that provide information that can help you argue for the interestingness of your research question. For a study on the effects of cell phone use on driving ability, for example, you might look for information about how widespread cell phone use is, how frequent and costly motor vehicle crashes are, and so on.
How many sources are enough for your literature review? This is a difficult question because it depends on how extensively your topic has been studied and also on your own goals. One study found that across a variety of professional journals in psychology, the average number of sources cited per article was about 50 (Adair & Vohra, 2003) [1] . This gives a rough idea of what professional researchers consider to be adequate. As a student, you might be assigned a much lower minimum number of references to use, but the principles for selecting the most useful ones remain the same.

- Demonstrates why a topic is significant to a subject area
- Helps focus your own research questions or problems
- Discovers relationships between research studies/ideas
- Suggests unexplored ideas or populations
- Identifies major themes, concepts, and researchers on a topic
- Tests assumptions; may help counter preconceived ideas and remove unconscious bias
- Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches

1. Choose a topic. Define your research question.
Your literature review should be guided by a central research question. It represents background and research developments related to a specific research question, interpreted, and analyzed by you in a synthesized way.
- Make sure your research question is not too broad or too narrow.
- Write down terms that are related to your question for they will be useful for searches later.
2. Decide on the scope of your review.
How many studies do you need to look at? How comprehensive should it be? How many years should it cover?
- This may depend on your assignment.
- Consider these things when planning your time for research.
3. Select the databases you will use to conduct your searches.
- By Research Guide
4. Conduct your searches and find the literature.
- Review the abstracts carefully - this will save you time!
- Many databases will have a search history tab for you to return to for later.
- Use bibliographies and references of research studies to locate others.
- Use citation management software such as Zotero to keep track of your research citations.
5. Review the literature.
Some questions to help you analyze the research:
- What was the research question you are reviewing? What are the authors trying to discover?
- Was the research funded by a source that could influence the findings?
- What were the research methodologies? Analyze the literature review, samples and variables used, results, and conclusions. Does the research seem complete? Could it have been conducted more soundly? What further questions does it raise?
- If there are conflicted studies, why do you think that is?
- How are the authors viewed in the field? Are they experts or novices? Has the study been cited?

A literature review is not a summary of the sources but a synthesis of the sources. It is made up of the topics the sources are discussing. Each section of the review is focused on a topic, and the relevant sources are discussed within the context of that topic.
1. Select the most relevant material from the sources
- Could be material that answers the question directly
- Extract as a direct quote or paraphrase
2. Arrange that material so you can focus on it apart from the source text itself
- You are now working with fewer words/passages
- Material is all in one place
3. Group similar points, themes, or topics together and label them
- The labels describe the points, themes, or topics that are the backbone of your paper’s structure
4. Order those points, themes, or topics as you will discuss them in the paper, and turn the labels into actual assertions
- A sentence that makes a point that is directly related to your research question or thesis

These are just a few examples of the many works of poetry that exist in literature. Poetry can explore a wide range of themes and emotions, using language and imagery to create powerful and moving works of art.
Prose is a type of written language that typically contains dialogue and narration. In literature, prose is the most common form of writing. Prose can be found in novels, short stories, plays, and essays.
Examples of Prose in Literature
“ The Essays” by Michel de Montaigne (1580) – This collection of prose is a seminal work of the French Renaissance and is credited with popularizing the use of personal reflections in prose literature. Montaigne’s writing style in these works is informal and conversational, and covers a vast range of topics including morality, philosophy, religion, and politics. The prose is notable for its intimacy and personal nature, as Montaigne often uses his own experiences and thoughts to illustrate his ideas.
A novel is a fictional book that is typically longer than 300 pages. It tells a story, usually in chronological order, and has characters and settings that are developed over the course of the story. Novels are often divided into chapters, which help to break up the story and make it easier to read.
Novels are one of the most popular genres of literature, and there are many different types of novels that you can read. Whether you’re looking for a romance novel, a mystery novel, or a historical fiction novel, there’s sure to be a book out there that you’ll love.
Examples of Novels in Literature

A novella is a work of fiction that is shorter than a novel but longer than a short story. The word “novella” comes from the Italian word for “new”, which is fitting because this type of story is often seen as being between the old and the new. In terms of length, a novella typically has about 20,000 to 40,000 words.
While novels are usually about one main plot with several subplots, novellas are usually focused on one central conflict. This conflict is usually resolved by the end of the story. However, because novellas are longer than short stories, there is more room to develop characters and explore themes in depth.
Examples of Novella in Literature

It is a cautionary tale about the dangers of totalitarianism and propaganda.
A short story is a work of fiction that typically can be read in one sitting and focuses on a self-contained incident or series of linked incidents.
The short story is one of the oldest forms of literature and has been found in oral cultures as well as in written form. In terms of length, it is much shorter than the novel, typically ranging from 1,000 to 20,000 words.
The short story has often been described as a “perfect form” because it allows for greater compression and variety than either the novel or poem. It also allows writers to experiment with different styles and genres.
Examples of Short Story in Literature

It follows the story of a woman who is confined to her bedroom and becomes obsessed with the yellow wallpaper on the walls.
A graphic novel is a book that tells a story through the use of illustrations and text. Graphic novels can be based on true stories, or they can be fictional. They are usually longer than traditional books, and they often have more complex plots.
Graphic novels first gained popularity in the 1970s, when publishers began releasing collections of comics that had been previously published in magazines. Since then, the genre has grown to include original works, as well as adaptations ofexisting stories.
Graphic novels are now widely respected as a form of literature, and they have been adapted into many different mediums, including movies, television shows, and stage plays.

Universal Themes and Human Experience:
Literature explores universal themes and the complexities of the human experience. Whether it’s love, loss, identity, or the pursuit of meaning, these themes resonate with readers across time and cultures. Literary works offer insights into the depths of human emotions, dilemmas, and aspirations, creating a shared understanding and connecting individuals across generations.
Intellectual and Personal Development:
Reading literature stimulates intellectual growth and personal development. It encourages critical thinking, analytical skills, and the ability to empathize with diverse perspectives. Literary works challenge readers to reflect on their own lives, values, and beliefs, promoting self-discovery and personal growth.
Enduring Literary Characters:
Iconic literary characters have a lasting impact on popular culture and the collective imagination. Characters like Sherlock Holmes, Hamlet, or Elizabeth Bennet have become archetypes, influencing the portrayal of similar characters in other works and becoming a part of our cultural lexicon.
Preservation of History and Memory:
Literature plays a crucial role in preserving historical events, experiences, and cultural memories. Historical novels, memoirs, and eyewitness accounts provide valuable insights into past eras, allowing future generations to learn from and connect with the past.

How to Write a Research Proposal: A Complete Guide
![research literature def Research Proposal](https://cdn.prod.website-files.com/5e98914ac6941ec9f6417987/66cc371aac16d69dd7f9c8f7_banner%20How%20to%20Write%20a%20Research%20Proposal-(Compressify.io).webp)
A research proposal is a piece of writing that basically serves as your plan for a research project. It spells out what you’ll study, how you’ll go about it, and why it matters. Think of it as your pitch to show professors or funding bodies that your project is worth their attention and support.
This task is standard for grad students, especially those in research-intensive fields. It’s your chance to showcase your ability to think critically, design a solid study, and articulate why your research could make a difference.
In this article, we'll talk about how to craft a good research proposal, covering everything from the standard format of a research proposal to the specific details you'll need to include.
Feeling overwhelmed by the idea of putting one together? That’s where DoMyEssay comes in handy. Whether you need a little push or more extensive guidance, we’ll help you nail your proposal and move your project forward.
Research Proposal Format
When you're putting together a research proposal, think of it as setting up a roadmap for your project. You want it to be clear and easy to follow so everyone knows what you’re planning to do, how you’re going to do it, and why it matters.
Whether you’re following APA or Chicago style, the key is to keep your formatting clean so that it’s easy for committees or funding bodies to read through and understand.
Here’s a breakdown of each section, with a special focus on formatting a research proposal:
- Title Page : This is your first impression. Make sure it includes the title of your research proposal, your name, and your affiliations. Your title should grab attention and make it clear what your research is about.
- Abstract : This is your elevator pitch. In about 250 words, you need to sum up what you plan to research, how you plan to do it, and what impact you think it will have.
- Introduction : Here’s where you draw them in. Lay out your research question or problem, highlight its importance, and clearly outline what you aim to achieve with your study.
- Literature Review : Show that you’ve done your homework. In this section, demonstrate that you know the field and how your research fits into it. It’s your chance to connect your ideas to what’s already out there and show off a bit about what makes your approach unique or necessary.
- Methodology : Dive into the details of how you’ll get your research done. Explain your methods for gathering data and how you’ll analyze it. This is where you reassure them that your project is doable and you’ve thought through all the steps.
- Timeline : Keep it realistic. Provide an estimated schedule for your research, breaking down the process into manageable stages and assigning a timeline for each phase.
- Budget : If you need funding, lay out a budget that spells out what you need money for. Be clear and precise so there’s no guesswork involved about what you’re asking for.
- References/Bibliography : List out all the works you cited in your proposal. Stick to one citation style to keep things consistent.
Get Your Research Proposal Right
Let our experts guide you through crafting a research proposal that stands out. From idea to submission, we've got you covered.
![research literature def](https://cdn.prod.website-files.com/5e98914ac6941ec9f6417987/659fd7099f06ab78b0fdf8a2_image%2010.png)
Research Proposal Structure
When you're writing a research proposal, you're laying out your questions and explaining the path you're planning to take to tackle them. Here’s how to structure your proposal so that it speaks to why your research matters and should get some attention.
Introduction
An introduction is where you grab attention and make everyone see why what you're doing matters. Here, you’ll pose the big question of your research proposal topic and show off the potential of your research right from the get-go:
- Grab attention : Start with something that makes the reader sit up — maybe a surprising fact, a challenging question, or a brief anecdote that highlights the urgency of your topic.
- Set the scene : What’s the broader context of your work? Give a snapshot of the landscape and zoom in on where your research fits. This helps readers see the big picture and the niche you’re filling.
- Lay out your plan : Briefly mention the main goals or questions of your research. If you have a hypothesis, state it clearly here.
- Make it matter : Show why your research needs to happen now. What gaps are you filling? What changes could your findings inspire? Make sure the reader understands the impact and significance of your work.
Literature Review
In your research proposal, the literature review does more than just recap what’s already out there. It's where you get to show off how your research connects with the big ideas and ongoing debates in your field. Here’s how to make this section work hard for you:
- Connect the dots : First up, highlight how your study fits into the current landscape by listing what others have done and positioning your research within it. You want to make it clear that you’re not just following the crowd but actually engaging with and contributing to real conversations.
- Critique what’s out there : Explore what others have done well and where they’ve fallen short. Pointing out the gaps or where others might have missed the mark helps set up why your research is needed and how it offers something different.
- Build on what’s known : Explain how your research will use, challenge, or advance the existing knowledge. Are you closing a key gap? Applying old ideas in new ways? Make it clear how your work is going to add something new or push existing boundaries.
Aims and Objectives
Let's talk about the aims and objectives of your research. This is where you set out what you want to achieve and how you plan to get there:
- Main Goal : Start by stating your primary aim. What big question are you trying to answer, or what hypothesis are you testing? This is your research's main driving force.
- Detailed Objectives : Now, break down your main goal into smaller, actionable objectives. These should be clear and specific steps that will help you reach your overall aim. Think of these as the building blocks of your research, each one designed to contribute to the larger goal.
Research Design and Method
This part of your proposal outlines the practical steps you’ll take to answer your research questions:
- Type of Research : First off, what kind of research are you conducting? Will it be qualitative or quantitative research , or perhaps a mix of both? Clearly define whether you'll be gathering numerical data for statistical analysis or exploring patterns and theories in depth.
- Research Approach : Specify whether your approach is experimental, correlational, or descriptive. Each of these frameworks has its own way of uncovering insights, so choose the one that best fits the questions you’re trying to answer.
- Data Collection : Discuss the specifics of your data. If you’re in the social sciences, for instance, describe who or what you’ll be studying. How will you select your subjects or sources? What criteria will you use, and how will you gather your data? Be clear about the methods you’ll use, whether that’s surveys, interviews, observations, or experiments.
- Tools and Techniques : Detail the tools and techniques you'll use to collect your data. Explain why these tools are the best fit for your research goals.
- Timeline and Budget : Sketch out a timeline for your research activities. How long will each phase take? This helps everyone see that your project is organized and feasible.
- Potential Challenges : What might go wrong? Think about potential obstacles and how you plan to handle them. This shows you’re thinking ahead and preparing for all possibilities.
Ethical Considerations
When you're conducting research, especially involving people, you've got to think about ethics. This is all about ensuring everyone's rights are respected throughout your study. Here’s a quick rundown:
- Participant Rights : You need to protect your participants' rights to privacy, autonomy, and confidentiality. This means they should know what the study involves and agree to participate willingly—this is what we call informed consent.
- Informed Consent : You've got to be clear with participants about what they’re signing up for, what you’ll do with the data, and how you'll keep it confidential. Plus, they need the freedom to drop out any time they want.
- Ethical Approval : Before you even start collecting data, your research plan needs a green light from an ethics committee. This group checks that you’re set up to keep your participants safe and treated fairly.
You need to carefully calculate the costs for every aspect of your project. Make sure to include a bit extra for those just-in-case scenarios like unexpected delays or price hikes. Every dollar should have a clear purpose, so justify each part of your budget to ensure it’s all above board. This approach keeps your project on track financially and avoids any surprises down the line.
The appendices in your research proposal are where you stash all the extra documents that back up your main points. Depending on your project, this could include things like consent forms, questionnaires, measurement tools, or even a simple explanation of your study for participants.
Just like any academic paper, your research proposal needs to include citations for all the sources you’ve referenced. Whether you call it a references list or a bibliography, the idea is the same — crediting the work that has informed your research. Make sure every source you’ve cited is listed properly, keeping everything consistent and easy to follow.

Meditation has a history that goes back thousands of years, and many meditative techniques began in Eastern traditions. The term “meditation” refers to a variety of practices that focus on mind and body integration and are used to calm the mind and enhance overall well-being. Some types of meditation involve maintaining mental focus on a particular sensation, such as breathing, a sound, a visual image, or a mantra, which is a repeated word or phrase. Other forms of meditation include the practice of mindfulness, which involves maintaining attention or awareness on the present moment without making judgments.
Programs that teach meditation or mindfulness may combine the practices with other activities. For example, mindfulness-based stress reduction is a program that teaches mindful meditation, but it also includes discussion sessions and other strategies to help people apply what they have learned to stressful experiences. Mindfulness-based cognitive therapy integrates mindfulness practices with aspects of cognitive behavioral therapy.

Meditation and mindfulness practices usually are considered to have few risks. However, few studies have examined these practices for potentially harmful effects, so it isn’t possible to make definite statements about safety.

A 2020 review examined 83 studies (a total of 6,703 participants) and found that 55 of those studies reported negative experiences related to meditation practices. The researchers concluded that about 8 percent of participants had a negative effect from practicing meditation, which is similar to the percentage reported for psychological therapies. The most commonly reported negative effects were anxiety and depression. In an analysis limited to 3 studies (521 participants) of mindfulness-based stress reduction programs, investigators found that the mindfulness practices were not more harmful than receiving no treatment.

According to the National Health Interview Survey, an annual nationally representative survey, the percentage of U.S. adults who practiced meditation more than doubled between 2002 and 2022, from 7.5 to 17.3 percent. Of seven complementary health approaches for which data were collected in the 2022 survey, meditation was the most popular, beating out yoga (used by 15.8 percent of adults), chiropractic care (11.0 percent), massage therapy (10.9 percent), guided imagery/progressive muscle relaxation (6.4 percent), acupuncture (2.2 percent), and naturopathy (1.3 percent).
For children aged 4 to 17 years, data are available for 2017; in that year, 5.4 percent of U.S. children used meditation.

In a 2012 U.S. survey, 1.9 percent of 34,525 adults reported that they had practiced mindfulness meditation in the past 12 months. Among those responders who practiced mindfulness meditation exclusively, 73 percent reported that they meditated for their general wellness and to prevent diseases, and most of them (approximately 92 percent) reported that they meditated to relax or reduce stress. In more than half of the responses, a desire for better sleep was a reason for practicing mindfulness meditation.

Meditation and mindfulness practices may have a variety of health benefits and may help people improve the quality of their lives. Recent studies have investigated if meditation or mindfulness helps people manage anxiety, stress, depression, pain, or symptoms related to withdrawal from nicotine, alcohol, or opioids.
Other studies have looked at the effects of meditation or mindfulness on weight control or sleep quality.
However, much of the research on these topics has been preliminary or not scientifically rigorous. Because the studies examined many different types of meditation and mindfulness practices, and the effects of those practices are hard to measure, results from the studies have been difficult to analyze and may have been interpreted too optimistically.

- A 2018 NCCIH-supported analysis of 142 groups of participants with diagnosed psychiatric disorders such as anxiety or depression examined mindfulness meditation approaches compared with no treatment and with established evidence-based treatments such as cognitive behavioral therapy and antidepressant medications. The analysis included more than 12,000 participants, and the researchers found that for treating anxiety and depression, mindfulness-based approaches were better than no treatment at all, and they worked as well as the evidence-based therapies.
- A 2021 analysis of 23 studies (1,815 participants) examined mindfulness-based practices used as treatment for adults with diagnosed anxiety disorders. The studies included in the analysis compared the mindfulness-based interventions (alone or in combination with usual treatments) with other treatments such cognitive behavioral therapy, psychoeducation, and relaxation. The analysis showed mixed results for the short-term effectiveness of the different mindfulness-based approaches. Overall, they were more effective than the usual treatments at reducing the severity of anxiety and depression symptoms, but only some types of mindfulness approaches were as effective as cognitive behavioral therapy. However, these results should be interpreted with caution because the risk of bias for all of the studies was unclear. Also, the few studies that followed up with participants for periods longer than 2 months found no long-term effects of the mindfulness-based practices.
- A 2019 analysis of 23 studies that included a total of 1,373 college and university students looked at the effects of yoga, mindfulness, and meditation practices on symptoms of stress, anxiety, and depression. Although the results showed that all the practices had some effect, most of the studies included in the review were of poor quality and had a high risk of bias.

Few high-quality studies have examined the effects of meditation and mindfulness on blood pressure. According to a 2017 statement from the American Heart Association, the practice of meditation may have a possible benefit, but its specific effects on blood pressure have not been determined.
- A 2020 review of 14 studies (including more than 1,100 participants) examined the effects of mindfulness practices on the blood pressure of people who had health conditions such as hypertension, diabetes, or cancer. The analysis showed that for people with these health conditions, practicing mindfulness-based stress reduction was associated with a significant reduction in blood pressure.

Studies examining the effects of mindfulness or meditation on acute and chronic pain have produced mixed results.
- A 2020 report by the Agency for Healthcare Research and Quality concluded that mindfulness-based stress reduction was associated with short-term (less than 6 months) improvement in low-back pain but not fibromyalgia pain.
- A 2020 NCCIH-supported analysis of five studies of adults using opioids for acute or chronic pain (with a total of 514 participants) found that meditation practices were strongly associated with pain reduction.
- Acute pain, such as pain from surgery, traumatic injuries, or childbirth, occurs suddenly and lasts only a short time. A 2020 analysis of 19 studies examined the effects of mindfulness-based therapies for acute pain and found no evidence of reduced pain severity. However, the same analysis found some evidence that the therapies could improve a person’s tolerance for pain.
- A 2017 analysis of 30 studies (2,561 participants) found that mindfulness meditation was more effective at decreasing chronic pain than several other forms of treatment. However, the studies examined were of low quality.
- A 2019 comparison of treatments for chronic pain did an overall analysis of 11 studies (697 participants) that evaluated cognitive behavioral therapy, which is the usual psychological intervention for chronic pain; 4 studies (280 participants) that evaluated mindfulness-based stress reduction; and 1 study (341 participants) of both therapies. The comparison found that both approaches were more effective at reducing pain intensity than no treatment, but there was no evidence of any important difference between the two approaches.
- A 2019 review found that mindfulness-based approaches did not reduce the frequency, length, or pain intensity of headaches. However, the authors of this review noted that their results are likely imprecise because only five studies (a total of 185 participants) were included in the analysis, and any conclusions made from the analysis should be considered preliminary.

Mindfulness meditation practices may help reduce insomnia and improve sleep quality.
- A 2019 analysis of 18 studies (1,654 total participants) found that mindfulness meditation practices improved sleep quality more than education-based treatments. However, the effects of mindfulness meditation approaches on sleep quality were no different than those of evidence-based treatments such as cognitive behavioral therapy and exercise.

Several clinical trials have investigated if mindfulness-based approaches such as mindfulness-based relapse prevention (MBRP) might help people recover from substance use disorders. These approaches have been used to help people increase their awareness of the thoughts and feelings that trigger cravings and learn ways to reduce their automatic reactions to those cravings.
- A 2018 review of 37 studies (3,531 total participants) evaluated the effectiveness of several mindfulness-based approaches to substance use disorder treatment and found that they significantly decreased participants’ craving levels. The mindfulness-based practices were slightly better than other therapies at promoting abstinence from substance use.
- A 2017 analysis specifically focused on MBRP examined 9 studies (901 total participants) of this approach. The analysis concluded that MBRP was not more effective at preventing substance use relapses than other treatments such as health education and cognitive behavioral therapy. However, MBRP did slightly reduce cravings and symptoms of withdrawal associated with alcohol use disorders.

Studies have suggested that meditation and mindfulness may help reduce symptoms of post-traumatic stress disorder (PTSD).
- A 2018 review supported by NCCIH examined the effects of meditation (in 2 studies, 179 total participants) and other mindfulness-based practices (in 6 studies, 332 total participants) on symptoms of PTSD. Study participants included veterans, nurses, and people who experienced interpersonal violence. Six of the eight studies reported that participants had a reduction of PTSD symptoms after receiving some form of mindfulness-based treatment.
- A 2018 clinical trial funded by the U.S. Department of Defense compared the effectiveness of meditation, health education, and prolonged exposure therapy, a widely accepted treatment for PTSD recommended by the American Psychological Association. Prolonged exposure therapy helps people reduce their PTSD symptoms by teaching them to gradually remember traumatic memories, feelings, and situations. The study included 203 veterans with PTSD as a result of their active military service. The results of the study showed that meditation was as effective as prolonged exposure therapy at reducing PTSD symptoms and depression, and it was more effective than PTSD health education. The veterans who used meditation also showed improvement in mood and overall quality of life.

Mindfulness-based approaches may improve the mental health of people with cancer.
- A 2019 analysis of 29 studies (3,274 total participants) of mindfulness-based practices showed that use of mindfulness practices among people with cancer significantly reduced psychological distress, fatigue, sleep disturbance, pain, and symptoms of anxiety and depression. However, most of the participants were women with breast cancer, so the effects may not be similar for other populations or other types of cancer.

Studies have suggested possible benefits of meditation and mindfulness programs for losing weight and managing eating behaviors.
- A 2017 review of 15 studies (560 total participants) looked at the effects of mindfulness-based practices on the mental and physical health of adults with obesity or who were overweight. The review found that these practices were very effective methods for managing eating behaviors but less effective at helping people lose weight. Mindfulness-based approaches also helped participants manage symptoms of anxiety and depression.
- A 2018 analysis of 19 studies (1,160 total participants) found that mindfulness programs helped people lose weight and manage eating-related behaviors such as binge, emotional, and restrained eating. The results of the analysis showed that treatment programs, such as mindfulness-based stress reduction and mindfulness-based cognitive therapy, that combine formal meditation and mindfulness practices with informal mindfulness exercises were especially effective methods for losing weight and managing eating.

Several studies have been done on using meditation and mindfulness practices to improve symptoms of attention-deficit hyperactivity disorder (ADHD). However, the studies have not been of high quality and the results have been mixed, so evidence that meditation or mindfulness approaches will help people manage symptoms of ADHD is not conclusive.

Some research suggests that meditation and mindfulness practices may affect the functioning or structure of the brain. Studies have used various methods of measuring brain activity to look for measurable differences in the brains of people engaged in mindfulness-based practices. Other studies have theorized that training in meditation and mindfulness practices can change brain activity. However, the results of these studies are difficult to interpret, and the practical implications are not clear.

GCSE results day 2024: Everything you need to know including the number grading system
![research literature def](https://educationhub.blog.gov.uk/wp-content/uploads/sites/185/2024/08/GCSE_Results_Hubheader_0824b.png)
Thousands of students across the country will soon be finding out their GCSE results and thinking about the next steps in their education.
Here we explain everything you need to know about the big day, from when results day is, to the current 9-1 grading scale, to what your options are if your results aren’t what you’re expecting.
When is GCSE results day 2024?
GCSE results day will be taking place on Thursday the 22 August.
The results will be made available to schools on Wednesday and available to pick up from your school by 8am on Thursday morning.
Schools will issue their own instructions on how and when to collect your results.
When did we change to a number grading scale?
The shift to the numerical grading system was introduced in England in 2017 firstly in English language, English literature, and maths.
By 2020 all subjects were shifted to number grades. This means anyone with GCSE results from 2017-2020 will have a combination of both letters and numbers.
The numerical grading system was to signal more challenging GCSEs and to better differentiate between students’ abilities - particularly at higher grades between the A *-C grades. There only used to be 4 grades between A* and C, now with the numerical grading scale there are 6.
What do the number grades mean?
The grades are ranked from 1, the lowest, to 9, the highest.
The grades don’t exactly translate, but the two grading scales meet at three points as illustrated below.
![research literature def The image is a comparison chart from the UK Department for Education, showing the new GCSE grades (9 to 1) alongside the old grades (A* to G). Grade 9 aligns with A*, grades 8 and 7 with A, and so on, down to U, which remains unchanged. The "Results 2024" logo is in the bottom-right corner, with colourful stripes at the top and bottom.](https://educationhub.blog.gov.uk/wp-content/uploads/sites/185/2024/08/results-day.png)
The bottom of grade 7 is aligned with the bottom of grade A, while the bottom of grade 4 is aligned to the bottom of grade C.
Meanwhile, the bottom of grade 1 is aligned to the bottom of grade G.
What to do if your results weren’t what you were expecting?
If your results weren’t what you were expecting, firstly don’t panic. You have options.
First things first, speak to your school or college – they could be flexible on entry requirements if you’ve just missed your grades.
They’ll also be able to give you the best tailored advice on whether re-sitting while studying for your next qualifications is a possibility.
If you’re really unhappy with your results you can enter to resit all GCSE subjects in summer 2025. You can also take autumn exams in GCSE English language and maths.
Speak to your sixth form or college to decide when it’s the best time for you to resit a GCSE exam.
Look for other courses with different grade requirements
Entry requirements vary depending on the college and course. Ask your school for advice, and call your college or another one in your area to see if there’s a space on a course you’re interested in.
Consider an apprenticeship
Apprenticeships combine a practical training job with study too. They’re open to you if you’re 16 or over, living in England, and not in full time education.
As an apprentice you’ll be a paid employee, have the opportunity to work alongside experienced staff, gain job-specific skills, and get time set aside for training and study related to your role.
You can find out more about how to apply here .
Talk to a National Careers Service (NCS) adviser
The National Career Service is a free resource that can help you with your career planning. Give them a call to discuss potential routes into higher education, further education, or the workplace.
Whatever your results, if you want to find out more about all your education and training options, as well as get practical advice about your exam results, visit the National Careers Service page and Skills for Careers to explore your study and work choices.

1. From Nutrients to Foods: The Emergence of the Food Matrix
2. dairy foods as examples of food matrices: the dairy matrix, 3. the application of the food matrix and dairy matrix concepts in the literature, 4. definitions of the food and the dairy matrices, 5. implementing the food/dairy matrix concept into nutrition policies and practices, 6. conclusions, author contributions, conflicts of interest.
Definition/Relevant Snippets | References |
---|---|
Some aspects of a food matrix: “the understanding of digestion mechanisms of major nutrients gained from the studies that use individual ingredients will be useful in reaching another level of complexity—the microstructural organizationof a real food matrix.” | [ ] |
“Food matrix effect is the difference between the effects of a sum of nutrients and those of a food. It reflects the fact that beyond nutrients there is non nutritive components, physico-chemical structures, interactions between nutrients, different bioavailability, which may explain some specific effects of foods, particularly when they are whole or not refined foods.” | [ ] |
“The nature of the food structure and the nutrients therein (i.e., the food matrix)” | [ ] |
“The matrix effect of a food goes beyond the individual nutrients, suggesting that the physical structure, created by a combination of nutritive components, can act independently of its individual components during digestion and metabolism” | [ ] |
“The food matrix describes foods in the context of both their structure, and their nutrient content, with the goal of understanding how these interact together” | [ ] |
The food matrix is referred to as “the nutrient and nonnutrient components of foods and their molecular relations.” | [ ] |
The food matrix is defined as whole foods | [ ] |
The food matrix is defined as whole foods | [ ] |
The food matrix is described as “the physical domain that interacts with specific constituents of a food” | [ ] |
“The food matrix, in essence the entire structure and composition of nutrients consumed by an individual, is gaining scientific recognition for its role in modulating the properties and metabolism of any single nutrient it contains.” | [ ] |
The food matrix is defined as “the food structure and nutrients therein” | [ ] |
“Overall composition and structure of foods needs to be considered, i.e., the food matrix effects.” | [ ] |
“The term ‘food matrix’ therefore describes the overall structure of a food, the spatial organisation of the nutrients and structures within it, and how these interact with each other.” | [ ] |
“This concept—referred to as the food matrix—considers all the attributes of food, including its microstructure, texture, and form (e.g., solid, gel, liquid), and how the nutrients and bioactive compounds are packaged and compartmentalized. Collectively, these attributes interact in ways that influence the digestion of food, the absorption of nutrients and bioactive compounds, and the physiological functions that impact health.” | [ ] |
“Whole food, i.e., its form and matrix, beyond the traditional approach of its individual nutrients and bioactive constituents” | [ ] |
Some relevant snippets: “evidence is increasing that the nutritional properties of a food ares not only determined by its single nutrients, but also by the complex food structure in which the nutrients are embedded. Thus, studies indicate that the food matrix can affect digestion and absorption of the nutrients in a given food.” | [ ] |
“Whole-food products contain multiple nutrients incorporated in a complex structure that can modulate food digestion and subsequent nutrient absorption, which is referred to as the food matrix. Consequently, this food matrix can strongly affect the metabolic impact of consumed nutrients.” | [ ] |

“Consumption of isolated dairy-derived nutrientshas been found to impact the risk of cardiometabolic disease differently compared to a whole dairy matrix. Dairy products considerably differ in the complexity of their food matrix due to processing methods (e.g., milk vs. cheese), which alters their nutrient types and composition, as well as physicalstructure.” | [ ] |

“The health impact of dairy fats and dairy foods must take into account their complex matrix (e.g., milk oligosaccharides, calcium, live and active cultures in yogurt, milk fat globule membranes and polar lipids, and bioactive peptides), which contribute to the gastrointestinal (GI) tract milieu of diet-derived factors that influence the host and microbiome.” | [ ] |

“The dairy matrix is not only the composition of nutrients, bioactive constituents, and other compounds present in milk and other dairy products but also how they are packaged and compartmentalized. It reflects the processing that the product undergoes, including changes in physical state of the product, altered endogenous constituents, and addition of inert and live chemicals or microorganisms.” | [ ] |

As mentioned previously, there are a number of existing guidelines for literature reviews. Depending on the methodology needed to achieve the purpose of the review, all types can be helpful and appropriate to reach a specific goal (for examples, please see Table 1).These approaches can be qualitative, quantitative, or have a mixed design depending on the phase of the review.
A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research. There are five key steps to writing a literature review: Search for relevant literature. Evaluate sources. Identify themes, debates and gaps.
Literature Review is a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.. Also, we can define a literature review as the collected body of scholarly works related to a topic:
A literature review is a written work that: Compiles significant research published on a topic by accredited scholars and researchers; Surveys scholarly articles, books, dissertations, conference proceedings, and other sources; Examines contrasting perspectives, theoretical approaches, methodologies, findings, results, conclusions.
