What is a Literature Review?
A literature review is a critical summary and evaluation of the existing research (e.g., academic journal articles and books) on a specific topic. It is typically included as a separate section or chapter of a research paper or dissertation, serving as a contextual framework for a study. Literature reviews can vary in length depending on the subject and nature of the study, with most being about equal length to other sections or chapters included in the paper. Essentially, the literature review highlights previous studies in the context of your research and summarizes your insights in a structured, organized format. Next, let’s look at the overall purpose of a literature review.

Literature reviews are considered an integral part of research across most academic subjects and fields. The primary purpose of a literature review in your study is to:
Provide a Foundation for Current Research
Since the literature review provides a comprehensive evaluation of the existing research, it serves as a solid foundation for your current study. It’s a way to contextualize your work and show how your research fits into the broader landscape of your specific area of study.
Define Key Concepts and Theories
The literature review highlights the central theories and concepts that have arisen from previous research on your chosen topic. It gives your readers a more thorough understanding of the background of your study and why your research is particularly significant .
Demonstrate Critical Evaluation
A comprehensive literature review shows your ability to critically analyze and evaluate a broad range of source material. And since you’re considering and acknowledging the contribution of key scholars alongside your own, it establishes your own credibility and knowledge.
Show How Research and Methodologies Have Evolved
Another purpose of literature reviews is to provide a historical perspective and demonstrate how research and methodologies have changed over time, especially as data collection methods and technology have advanced. And studying past methodologies allows you, as the researcher, to understand what did and did not work and apply that knowledge to your own research.
Identify Gaps in Existing Research
Besides discussing current research and methodologies, the literature review should also address areas that are lacking in the existing literature. This helps further demonstrate the relevance of your own research by explaining why your study is necessary to fill the gaps.
Support Your Argument
A good literature review should provide evidence that supports your research questions and hypothesis. For example, your study may show that your research supports existing theories or builds on them in some way. Referencing previous related studies shows your work is grounded in established research and will ultimately be a contribution to the field.

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.

Frequently asked questions
A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. 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. |

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

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.

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 .

Writing a Literature Review
Welcome to the Purdue OWL

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.
Where, when, and why would I write a lit review?
There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.
A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.
Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.
What are the parts of a lit review?
Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.
Introduction:
- An introductory paragraph that explains what your working topic and thesis is
- A forecast of key topics or texts that will appear in the review
- Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
- 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 sentence to draw connections, comparisons, and contrasts.
Conclusion:
- Summarize the key findings you have taken from the literature and emphasize their significance
- Connect it back to your primary research question
How should I organize my lit review?
Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:
- Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
- Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
- Qualitative versus quantitative research
- Empirical versus theoretical scholarship
- Divide the research by sociological, historical, or cultural sources
- Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.
What are some strategies or tips I can use while writing my lit review?
Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .
As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.
Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:
- It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
- Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
- Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
- Read more about synthesis here.
The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

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.

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.

Introduction to Literature ReviewsIntroduction.
A literature review is a written work that :
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. Olivia Whitfield | Graduate Reference Assistant | 2012-2015
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 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 literatureThe 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 chapterThe 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’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 knowledgeThe 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 fillThe 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 frameworkThe 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 methodologyThe 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. Example of a literature reviewIn the video below, we walk you through a high-quality literature review from a dissertation that earned full distinction. This will give you a clearer view of what a strong literature review looks like in practice and hopefully provide some inspiration for your own. Wrapping UpIn this post, we’ve (hopefully) answered the question, “ what is a literature review? “. We’ve also considered the purpose and functions of the literature review, as well as how to find literature and how to structure the literature review chapter.

A literature review is not only a summary of key sources, but has an organizational pattern which 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:

Conducting a Literature ReviewWhat is a literature review.
The literature of a literature review is not made up of novels and short stories and poetry—but is the collection of writing and research that has been produced on a particular topic. The purpose of the literature review is to give you an overview of a particular topic. Your job is to discover the research that has been done, the major perspectives, and the significant thinkers and writers (experts) who have published on the topic you’re interested in. In other words, it’s a survey of what has been written and argued about your topic. By the time you complete your literature review you should have written an essay that demonstrates that you:
Thus, a literature review synthesizes your research into an explanation of what is known and what is not known on your topic. If the topic is one from which you want to embark on a major research project, doing a literature review will save you time and help you figure out where you might focus your attention so you don’t duplicate research that has already been done. Just to be clear: a literature review differs from a research paper in that a literature review is a summary and synthesis of the major arguments and thinking of experts on the topic you’re investigating, whereas a research paper supports a position or an opinion you have developed yourself as a result of your own analysis of a topic. Another advantage of doing a literature review is that it summarizes the intellectual discussion that has been going on over the decades—or centuries—on a specific topic and allows you to join in that conversation (what academics call academic discourse) from a knowledgeable position. The following presentation will provide you with the basic steps to follow as you work to complete a literature review.

Types of Literature Review — A Guide for ResearchersTable of ContentsResearchers often face challenges when choosing the appropriate type of literature review for their study. Regardless of the type of research design and the topic of a research problem , they encounter numerous queries, including: What is the right type of literature review my study demands?
If you’re also dealing with such a hefty questionnaire, this article is of help. Read through this piece of guide to get an exhaustive understanding of the different types of literature reviews and their step-by-step methodologies along with a dash of pros and cons discussed. Heading from scratch! What is a Literature Review?A literature review provides a comprehensive overview of existing knowledge on a particular topic, which is quintessential to any research project. Researchers employ various literature reviews based on their research goals and methodologies. The review process involves assembling, critically evaluating, and synthesizing existing scientific publications relevant to the research question at hand. It serves multiple purposes, including identifying gaps in existing literature, providing theoretical background, and supporting the rationale for a research study. What is the importance of a Literature review in research?Literature review in research serves several key purposes, including:
Types of Literature ReviewLiterature review plays a crucial role in guiding the research process , from providing the background of the study to research dissemination and contributing to the synthesis of the latest theoretical literature review findings in academia. However, not all types of literature reviews are the same; they vary in terms of methodology, approach, and purpose. Let's have a look at the various types of literature reviews to gain a deeper understanding of their applications. 1. Narrative Literature ReviewA narrative literature review, also known as a traditional literature review, involves analyzing and summarizing existing literature without adhering to a structured methodology. It typically provides a descriptive overview of key concepts, theories, and relevant findings of the research topic. Unlike other types of literature reviews, narrative reviews reinforce a more traditional approach, emphasizing the interpretation and discussion of the research findings rather than strict adherence to methodological review criteria. It helps researchers explore diverse perspectives and insights based on the research topic and acts as preliminary work for further investigation. Steps to Conduct a Narrative Literature ReviewSource:- https://www.researchgate.net/figure/Steps-of-writing-a-narrative-review_fig1_354466408 Define the research question or topic:The first step in conducting a narrative literature review is to clearly define the research question or topic of interest. Defining the scope and purpose of the review includes — What specific aspect of the topic do you want to explore? What are the main objectives of the research? Refine your research question based on the specific area you want to explore. Conduct a thorough literature searchOnce the research question is defined, you can conduct a comprehensive literature search. Explore and use relevant databases and search engines like SciSpace Discover to identify credible and pertinent, scholarly articles and publications. Select relevant studiesBefore choosing the right set of studies, it’s vital to determine inclusion (studies that should possess the required factors) and exclusion criteria for the literature and then carefully select papers. For example — Which studies or sources will be included based on relevance, quality, and publication date? *Important (applies to all the reviews): Inclusion criteria are the factors a study must include (For example: Include only peer-reviewed articles published between 2022-2023, etc.). Exclusion criteria are the factors that wouldn’t be required for your search strategy (Example: exclude irrelevant papers, preprints, written in non-English, etc.) Critically analyze the literatureOnce the relevant studies are shortlisted, evaluate the methodology, findings, and limitations of each source and jot down key themes, patterns, and contradictions. You can use efficient AI tools to conduct a thorough literature review and analyze all the required information. Synthesize and integrate the findingsNow, you can weave together the reviewed studies, underscoring significant findings such that new frameworks, contrasting viewpoints, and identifying knowledge gaps. Discussion and conclusionThis is an important step before crafting a narrative review — summarize the main findings of the review and discuss their implications in the relevant field. For example — What are the practical implications for practitioners? What are the directions for future research for them? Write a cohesive narrative reviewOrganize the review into coherent sections and structure your review logically, guiding the reader through the research landscape and offering valuable insights. Use clear and concise language to convey key points effectively. Structure of Narrative Literature ReviewA well-structured, narrative analysis or literature review typically includes the following components:
Pros and Cons of Narrative Literature Review
Example of Well-Executed Narrative Literature ReviewsPaper title: Examining Moral Injury in Clinical Practice: A Narrative Literature Review Source: SciSpace While narrative reviews offer flexibility, academic integrity remains paramount. So, ensure proper citation of all sources and maintain a transparent and factual approach throughout your critical narrative review, itself. 2. Systematic ReviewA systematic literature review is one of the comprehensive types of literature review that follows a structured approach to assembling, analyzing, and synthesizing existing research relevant to a particular topic or question. It involves clearly defined criteria for exploring and choosing studies, as well as rigorous methods for evaluating the quality of relevant studies. It plays a prominent role in evidence-based practice and decision-making across various domains, including healthcare, social sciences, education, health sciences, and more. By systematically investigating available literature, researchers can identify gaps in knowledge, evaluate the strength of evidence, and report future research directions. Steps to Conduct Systematic ReviewsSource:- https://www.researchgate.net/figure/Steps-of-Systematic-Literature-Review_fig1_321422320 Here are the key steps involved in conducting a systematic literature review Formulate a clear and focused research questionClearly define the research question or objective of the review. It helps to centralize the literature search strategy and determine inclusion criteria for relevant studies. Develop a thorough literature search strategyDesign a comprehensive search strategy to identify relevant studies. It involves scrutinizing scientific databases and all relevant articles in journals. Plus, seek suggestions from domain experts and review reference lists of relevant review articles. Screening and selecting studiesEmploy predefined inclusion and exclusion criteria to systematically screen the identified studies. This screening process also typically involves multiple reviewers independently assessing the eligibility of each study. Data extractionExtract key information from selected studies using standardized forms or protocols. It includes study characteristics, methods, results, and conclusions. Critical appraisalEvaluate the methodological quality and potential biases of included studies. Various tools (BMC medical research methodology) and criteria can be implemented for critical evaluation depending on the study design and research quetions . Data synthesisAnalyze and synthesize review findings from individual studies to draw encompassing conclusions or identify overarching patterns and explore heterogeneity among studies. Interpretation and conclusionInterpret the findings about the research question, considering the strengths and limitations of the research evidence. Draw conclusions and implications for further research. The final step — Report writingCraft a detailed report of the systematic literature review adhering to the established guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). This ensures transparency and reproducibility of the review process. By following these steps, a systematic literature review aims to provide a comprehensive and unbiased summary of existing evidence, help make informed decisions, and advance knowledge in the respective domain or field. Structure of a systematic literature reviewA well-structured systematic literature review typically consists of the following sections:
*Important (applies to all the reviews): Remember, the specific structure of your literature review may vary depending on your topic, research question, and intended audience. However, adhering to a clear and logical hierarchy ensures your review effectively analyses and synthesizes knowledge and contributes valuable insights for readers.

Read this detailed article on how to use AI tools to conduct a systematic review for your research! 3. Scoping Literature ReviewA scoping literature review is a methodological review type of literature review that adopts an iterative approach to systematically map the existing literature on a particular topic or research area. It involves identifying, selecting, and synthesizing relevant papers to provide an overview of the size and scope of available evidence. Scoping reviews are broader in scope and include a diverse range of study designs and methodologies especially focused on health services research. The main purpose of a scoping literature review is to examine the extent, range, and nature of existing studies on a topic, thereby identifying gaps in research, inconsistencies, and areas for further investigation. Additionally, scoping reviews can help researchers identify suitable methodologies and formulate clinical recommendations. They also act as the frameworks for future systematic reviews or primary research studies. Scoping reviews are primarily focused on —
Steps to Conduct a Scoping Literature ReviewWhile Scoping reviews are not as rigorous as systematic reviews, however, they still follow a structured approach. Here are the steps: Identify the research question: Define the broad topic you want to explore. Identify Relevant Studies: Conduct a comprehensive search of relevant literature using appropriate databases, keywords, and search strategies. Select studies to be included in the review: Based on the inclusion and exclusion criteria, determine the appropriate studies to be included in the review. Data extraction and charting : Extract relevant information from selected studies, such as year, author, main results, study characteristics, key findings, and methodological approaches. However, it varies depending on the research question. Collate, summarize, and report the results: Analyze and summarize the extracted data to identify key themes and trends. Then, present the findings of the scoping review in a clear and structured manner, following established guidelines and frameworks . Structure of a Scoping Literature ReviewA scoping literature review typically follows a structured format similar to a systematic review. It includes the following sections:
Pros and Cons of Scoping Literature Review
In short, a scoping review helps map the literature on developing or emerging topics and identifying gaps. It might be considered as a step before conducting another type of review, such as a systematic review. Basically, acts as a precursor for other literature reviews. Example of a Well-Executed Scoping Literature ReviewPaper title: Health Chatbots in Africa Literature: A Scoping Review Check out the key differences between Systematic and Scoping reviews — Evaluating literature review: systematic vs. scoping reviews 4. Integrative Literature ReviewIntegrative Literature Review (ILR) is a type of literature review that proposes a distinctive way to analyze and synthesize existing literature on a specific topic, providing a thorough understanding of research and identifying potential gaps for future research. Unlike a systematic review, which emphasizes quantitative studies and follows strict inclusion criteria, an ILR embraces a more pliable approach. It works beyond simply summarizing findings — it critically analyzes, integrates, and interprets research from various methodologies (qualitative, quantitative, mixed methods) to provide a deeper understanding of the research landscape. ILRs provide a holistic and systematic overview of existing research, integrating findings from various methodologies. ILRs are ideal for exploring intricate research issues, examining manifold perspectives, and developing new research questions. Steps to Conduct an Integrative Literature Review

Rapid Literature ReviewA Rapid Literature Review (RLR) is the fastest type of literature review which makes use of a streamlined approach for synthesizing literature summaries, offering a quicker and more focused alternative to traditional systematic reviews. Despite employing identical research methods, it often simplifies or omits specific steps to expedite the process. It allows researchers to gain valuable insights into current research trends and identify key findings within a shorter timeframe, often ranging from a few days to a few weeks — unlike traditional literature reviews, which may take months or even years to complete.

There you go! Frequently Asked QuestionsNarrative reviews give a general overview of a topic based on the author's knowledge. They may lack clear criteria and can be biased. On the other hand, systematic reviews aim to answer specific research questions by following strict methods. They're thorough but time-consuming. A systematic review collects and analyzes existing research to provide an overview of a topic, while a meta-analysis statistically combines data from multiple studies to draw conclusions about the overall effect of an intervention or relationship between variables. A systematic review thoroughly analyzes existing research on a specific topic using strict methods. In contrast, a scoping review offers a broader overview of the literature without evaluating individual studies in depth. A systematic review thoroughly examines existing research using a rigorous process, while a rapid review provides a quicker summary of evidence, often by simplifying some of the systematic review steps to meet shorter timelines. A systematic review carefully examines many studies on a single topic using specific guidelines. Conversely, an integrative review blends various types of research to provide a more comprehensive understanding of the topic.

Boote and Baile 2005 Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review. Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected. The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions. Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research. It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them. For other researches, the literature review gives the direction to be headed for its success. The common perception of literature review and reality:As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic. But on the contrary, it uses published information from pertinent and relevant sources like

We also provide the following activities: Types of Literature Reviews [Refresher]Writing the literature review [refresher], the literature review [1]. Conducting a literary studies research project involves time and effort, with much of it going towards the development of a literature review . A literature review might fill several pages of your research paper and usually appears soon after an introduction but before you present your detailed argument. A literature review provides your audience with an overview of the available research about your area(s) of study, including the literary work, your theory, and methodology. The literature review demonstrates how these scholarly discussions have changed over time, and it allows you to position your research in relation to research that has come before yours. Your aim is to present the discussion up to this point. Depending on the nature of the assignment, you may also include your critical commentary on prior research, noting among this material the weaker and stronger arguments, breakthroughs and dead ends, blind spots and opportunities, the invention of key terms and methods, mistakes as well as misreadings, and so on. Once you have gathered the research materials you need for your literature review, you have another task: conducting an analysis on the research to see where your original contribution fits into the scholarly conversation. As the saying goes, “we are standing on the shoulders of giants.” Your job is to show a portrait of these giants to your audience, and to show how your work relates to the portrait. On many scholarly topics, literature reviews already exist. You may refer to such existing reviews within your own, indicating any materials might have been overlooked, new developments that have arisen since the publication of the existing literature review, and new perspectives or insights you have about the materials. Some beginning researchers try to tear down the work of other researchers in an effort to make their own work look good by comparison. It rarely works. First, it tends to make your audience skeptical of your claims. Second, it ignores the fact that even the mistakes, blind spots, and failures of other researchers contribute something to our knowledge. Albert Einstein didn’t disrespect Sir Isaac Newton by saying Newton’s theory of space was wrong and terrible and that Einstein’s own theory was great by comparison. He built upon Newton’s work, showing how it could be improved. If, however, a researcher willfully set out to deceive or distort or to tear down the work of other scholars without good reason, then their work does not deserve such deference. Most literature reviews appear after the introduction. It presents your reader with relevant information about the scholarly discussion up to now. Later in your paper, you discuss your contribution. Before you begin work on your literature review, let’s discuss what we mean by “literature”; understand the purpose and scope of the review; establish criteria for selecting, organizing, and interpreting your findings; and discuss how to connect your findings to your research question. Many students seek to “find sources that agree with my claim or idea.” That approach is too narrow, in our view. If we use such an approach, we may get the following results:
The literature review provides your reader with an overview of the existing research about your topic or problem. It provides the context necessary for your reader to catch up with the scholarly conversation and then to appreciate the value of your contribution to it. The literature review sharpens the focus of your research and demonstrates your knowledge and understanding of the scholarly conversation around your topic, which, in turn, helps establish your credibility as a researcher. Creating the literature review involves more than gathering citations. It is a qualitative process through which you will discover what is already known about your topic, and identify the key authorities, methods, and theoretical foundations, so you can begin to position your contributions within the scholarly conversation. Defining the scope of your review will also help you establish criteria to determine the relevance of the sources you are finding. At this stage, you are not reading in-depth; instead, you are skimming through what has already been published and identifying the major concepts, theories, methodologies, and methods present within these published works. You should also be identifying connections, tensions, and contradictions within the already published works of your topic or problem. This involves building on the knowledge of others and understanding what methods, measures, and models we have inherited from previous researchers in our field. Literature Reviews: Common Errors Made When Conducting a Literature Review [12 min 22 sec] Video provided courtesy of the Center for Quality Research (CQR) A literature review helps your reader understand the relationship of your research project to the work of other scholars. It covers the existing knowledge about a problem, and allows you to show the relevance/significance of your contribution to the discussion. Your reader may or may not have read scholarly literature about the theories, methodologies, and literary works you are discussing. But they want to know that you have read it and have thought about it. Your literature review provides not only a summary of the existing scholarship for readers; it also offers your perspective on it. Begin your work on the literature review by synthesizing the various sources in your annotated bibliography . For advice on Synthesizing Sources, consider the following from The Purdue Online Writing Lab: [2] Note that synthesizing is not the same as summarizing .
Not all humanities research projects contain literature reviews, but many do. Keep in mind that the type of literature review you choose (see list below) pertains to the secondary research – other scholarly sources – and not to the primary literary work. For instance, a literature review about Kate Chopin’s writing will be your thoughts about the scholarship on Chopin and not about Chopin’s text itself. You are summarizing what you see in the scholarly literature about Chopin’s writing. The literature review puts you in the position of authority not just on Chopin’s writing but on the scholarship about her writing. You are seeking to understand what scholars have said about her work. Scholars might belong to different schools of thought (psychoanalytic, feminist, Marxist, etc.). They might make different arguments about Chopin. They might use different methodological approaches. If your research involves two or more theories, such as psychology and genre studies, you may need to create multiple literature reviews, one for each theory or methodology. If the theories overlap with each other significantly (i.e., Marxism and Cultural Studies), you may combine them. Your literature review need not include everything about the subject area – you would need to write a book to cover a single theory – but only those concepts and methods that are most relevant to your research problem. Factors to Consider When Developing Your Literature Review
One piece of advice before starting: look for existing literature reviews on your area of scholarship. You can build on the work that other scholars have put into reviewing the scholarly literature. There’s no need to completely “reinvent the wheel” if some of the work is already done. Scholars sometimes publish “stand-alone” literature reviews that are not part of a larger work; such literature reviews are valuable contributions to the field, as they summarize the state of knowledge for other scholars. Maria J. Grant and Andrew Booth’s “A Typology of Reviews” identifies 14 distinct types of literature reviews. Further, the UCLA library created a chart to complement the article and for easy comparison of those 14 types of reviews. This section provides a brief summary of the most common literature reviews. For a more complete analysis, please see the full article and the chart . To choose the most appropriate structure, put yourself in your reader’s shoes and think through their need for information. The literature review is about providing context for your contribution. How much context do people need? Keep it to the minimum necessary; compressing a lot of information into a small amount of text is a must. These structures are not meant to be straightjackets but tools to help you organize your research. If you find that the tool is working, then keep using it. If not, switch tools or modify the one you are using. Keep in mind that the types of literature reviews are just different ways of organizing information. So, you can discuss literary trends without organizing your review of secondary literature by trend; your discussion can be organized by theory or theme, for examples. In our literature reviews, we are not recounting other scholars’ arguments at length but merely providing key concepts so we can summarize the discussion so far and position our own claims. You don’t have to adhere strictly to one structure or another. They are just organizing tools that help you manage your material (and help your reader make sense of it). Types of Reviews
An argumentative literature review presents and takes sides in scholarly arguments about the literary work. It makes arguments about other scholars’ work. It does not necessarily involve a claim that the literary work is itself making an argument. Likewise, a chronological literature review presents the scholarly literature in chronological order. You don’t need to keep strictly to one type. Scholars often combine features from various types of literature reviews. A sample review that combines the follow types –
– is the excellent work of Eiranen, Reetta, Mari Hatavara, Ville Kivimäki, Maria Mäkelä & Raisa Maria Toivo (2022) “ Narrative and Experience: Interdisciplinary Methodologies between History and Narratology , ” Scandinavian Journal of History , 47:1, 1-15 When writing your literature review, please follow these pointers:
Advice from James Mason University’s “Literature Reviews: An Overview”A note on synthesizing : Don’t make the common mistake of summarizing individual studies or articles one after the other. The goal is to synthesize — that is, to make observations about groups of studies. Synthesis often uses language like this:
Please see this sample annotated literature review from James Mason University. Structure of a literature review [2]
Literature reviews can be published as part of a scholarly article, often after the introduction and sometimes with a header, but they can also be published as a standalone essay. To find examples of what reviews look like in your discipline, choose an appropriate subject database (such as MLA for literary criticism) and conduct a keyword search with the term “Literature Review” added in quotes: Not only do these examples demonstrate how to structure different types of literature reviews, but some offer insights into trends and directions for future research. In the next section, we’ll take a closer look at some reading strategies to help guide you through this process. Since scholars already have produced literature reviews on various scholarly conversations, you don’t always need to “reinvent the wheel” (start a literature review from nothing). You can find a published literature review and update it or amend it; scholars do that all the time. However, you must properly cite work you incorporate from others.

Physical therapy students’ experiences of inappropriate patient sexual behavior: a narrative reviewArticle sidebar, main article content. Primary objective : The purpose of this study is to identify the extent to which inappropriate patient sexual behavior (IPSB) is directed toward student physical therapists (PTs) and how this phenomenon is described in the current literature. Review type : Narrative review. Summary of review method : A search of PubMed, CINAHL Plus, and Academic Search Complete was conducted using the Boolean phrase (‘sexual harassment’ OR ‘sexual assault’ OR ‘inappropriate sexual behavior’ OR ‘sexual behavior’) AND (‘physical therapy’ OR physiotherapy OR ‘physical therapist’ OR physiotherapist). After relevant articles were identified, references were searched for additional relevant material. Data and common themes were identified, extracted, and summarized. Primary results : Studies indicate that 84% to 92.9% of PTs have IPSBs directed at them during their careers. There is less information on the rate at which student PTs are targets of IPSB, but the available studies indicate 66.2% to 78% of them experience IPSB during their clinical experiences. In one study, over 22% of PT students experienced severe forms of IPSB during clinical experiences. Other studies show that student PTs and novice PTs respond to IPSB with techniques that are less effective than those used by experienced PTs. Qualitative reports indicate that student PTs feel that they and their clinical instructors are unprepared for IPSB and believe more training on the topic is necessary. Conclusion : The available literature indicates that most PT students have IPSB directed at them during their clinical experiences. Students report feeling unprepared and desire more training on this topic. Additional training may reduce IPSB.

BACKGROUND: While the diagnosis of frontotemporal dementia (FTD) is based mostly on clinical features, [18F]-FDG PET has been investigated as a potential imaging golden standard in ambiguous cases, with arterial spin labeling (ASL) MRI gaining recent interest. PURPOSE: The purpose of this study is to conduct a systematic review and meta-analysis on the diagnostic performance of ASL MRI in FTD patients and compare it to that of [18F]-FDG PET. DATA SOURCES: A systematic search of PubMed, Scopus and EMBASE was conducted until March 13, 2024. STUDY SELECTION: Inclusion criteria were: original articles, patients with FTD and/or its variants, use of ASL MR perfusion imaging with or without [18F]-FDG PET, presence of sufficient diagnostic performance data. Exclusion criteria were: meeting abstracts, comments, summaries, protocols, letters and guidelines, longitudinal studies, overlapping cohorts. DATA ANALYSIS: The quality of eligible studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. Pooled sensitivity, specificity, and diagnostic odds ratio (DOR) for [18F]-FDG PET and ASL MRI were calculated, and a summary receiver operating characteristic curve was plotted. DATA SYNTHESIS: Seven eligible studies were identified, which included a total of 102 FTD patients. Aside from some of the studies showing at worst an unclear risk of bias in patient selection, index test, flow and timing, all studies showed low risk of bias and applicability concerns in all categories. Data from 4 studies was included in our meta-analysis for ASL MRI and 3 studies for [18F]-FDG PET. Pooled sensitivity, specificity and DOR were 0.70 (95% CI: 0.59-0.79), 0.81 (95% CI: 0.71-0.88) and 8.00 (95% CI: 3.74-17.13) for ASL MRI, and 0.88 (95% CI: 0.71-0.96), 0.89 (95% CI: 0.43-0.99) and 47.18 (95% CI: 10.77-206.75) for [18F]-FDG PET. LIMITATIONS: The number of studies was relatively small, with a small sample size. The studies used different scanning protocols as well as a mix of diagnostic metrics, all of which might have introduced heterogeneity in the data. CONCLUSIONS: While ASL MRI performed worse than [18F]-FDG PET in the diagnosis of FTD, it exhibited a decent diagnostic performance to justify its further investigation as a quicker and more convenient alternative.
