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.

✍️ Literature Review Writing Tips

Speaking of a literature review , the definition is too broad to be used as writing guidance. It is an overview of credible materials on a particular research question. A literature review usually becomes chapter 1 in dissertations and theses , allowing to explore the current knowledge on the topic. It evaluates academic and professional articles, journal publications, books, and web-based resources.

A literature review is an indispensable part of a research paper. It serves many purposes, some of which are not evident.

What Is the Purpose of a Literature Review?

• To draw the background context;
• To compare your results with previous research;
• To justify your research methods;
• To frame research gaps and show the scientific novelty of your project;
• To explain the social value of your work;
• To demonstrate your knowledge of the referenced literature;
• To train your analytical thinking.

Types of Literature Review

Below you’ll find the 6 types of literature reviews.

Systematic Review

A systematic literature review is a most comprehensive and data-oriented type. It defines the timeframe of the selected literature and is subdivided into two categories:

• Meta-analysis ( deductive research through standardized statistical procedures)
• Meta-synthesis (inductive study by non-statistical qualitative methods)

Narrative Review

It is also called a traditional or critical literature review. The purpose is to summarize the available material, critique it, and identify the gaps and inconsistencies. This type works well for almost any research question, provided it is sufficiently focused and limited in time or subject matter.

Scoping Review

As the name implies, it estimates the scope of available literature on a literature review topic. Unlike a systematic literature review, which aims to find the most specific research question, this type looks for the most general one. It answers the question of what else can be researched in the field.

Theoretical Review

A theoretical literature review explores the pool of theories that have so far accumulated on a concept. It lists the existing ideas, their relationships, and gaps. The purpose is to develop hypotheses to be tested in the experimental section.

Argumentative Review

This type provides the most selective literature review to prove or refute an argument already established in the research literature. However, this is also the most biased review among all types.

Integrative Review

This literature review integrates, synthesizes, and critiques the available secondary data to develop new research frameworks and perspectives.

Systematic Review vs. Literature Review vs. Annotated Bibliography

• Purpose: Eliminate bias and answer a focused question.
• Structure: Introduction – Methodology – Discussion – Conclusion – List of References.
• Number of sources: 3+
• Scope: Clearly defined (narrow) research question.
• Relationship between so urces: How do they answer my research question?
• Organization: Evidence-based inductions or deductions.
• Purpose: Summarize the most significant sources on the topic.
• Structure: Intro – Methods – Discussion – Conclusion – References.
• Number of sources: 1+
• Scope: Either a general topic or a specific question.
• Relationship between sources: Do they agree or disagree?
• Organization: Cause-and-effect, comparison or contrast, and classification.
• Purpose: List the most suitable sources for additional reading with brief explanations.
• Structure: Numbered list according to a formal citation style (APA, MLA, or Chicago) plus a brief explanation of relevance and credibility of sources.
• Number of sources: 15-20
• Scope: General topic.
• Relationship between sources: How do they relate to the topic?
• Organization: Alphabetical order.

What Are the Four Stages of Literature Review?

The process of conducting a literature review can be divided into four stages:

• Formulating the problem. Choose a topic and its specific aspects.
• Searching the literature. Make up the preliminary bibliography list to be described in the literature review.
• Evaluating the data. Decide which sources are the most significant in understanding the topic.
• Analyzing and interpreting the essential findings.

Literature Review Outline

How long should a literature review be? It depends on the assignment requirements and your outline.

A literature review is often used as a part of a more general research paper. In such a case, you can limit yourself to the standard introduction –main body – conclusion formula.

In all the other situations, use the following literature review outline.

• Introduction Trace the scope and highlight the importance of your review. Why did you choose the given topic or research question? How does it contribute to the previous study?
• Methodology We have listed the types of literature review above. Depending on your purposes, select one and explain why your choice is the best. You can also specify which logic you used while choosing the sources for your review.
• Discussion It is the central part of the text which compares, contrasts, and explains the relationships between various ideas you found in the bibliography items.
• Conclusion Are you satisfied with the result of your work? How will it help further research? Which gaps have you spotted, and which hypothesis could you generate?
• List of references As in any research paper, this is an indispensable part of your literature review. Be sure to follow the format requirements as provided below.

Literature Review Format

All citation styles require you to indicate the author’s name, book title, publication year, number of pages, and volume or issue number. This data is available in any printed edition, as publishers use it to identify their products.

It may sound simple until you discover that each citation style has a multi-page list of nuanced details specific to this format and inapplicable to any other.

Browse the guides for each of the most popular types below.

APA style is a format for scholarly documents. It is particularly popular in the fields of social and behavioral sciences. APA is well-known for its simplicity in source references. Thus, a vast majority of American universities and colleges prefer this format.

MLA style manual is an abridged version of the MLA Handbook published by the Modern Language Association. It was created for students to assist in their research aspirations. Its 8 th edition is addressed to secondary-school and undergraduate university and college teachers and students. The style is popular in humanities (modern languages, literature, cultural studies, and related disciplines).

Chicago style (also called CMS or CMOS) is a style guide for American English. The University of Chicago Press first published it in 1906. Since then, it has had 17 editions and has become one of the most popular citation styles in the US. The guide instructs on editorial practice, grammar, document preparation, formatting, and even the use of the singular “they.”

Learn about our Editorial Process

Literature reviews are a necessary step in a research process and often required when writing your research proposal . They involve gathering, analyzing, and evaluating existing knowledge about a topic in order to find gaps in the literature where future studies will be needed.

Ideally, once you have completed your literature review, you will be able to identify how your research project can build upon and extend existing knowledge in your area of study.

Generally, for my undergraduate research students, I recommend a narrative review, where themes can be generated in order for the students to develop sufficient understanding of the topic so they can build upon the themes using unique methods or novel research questions.

If you’re in the process of writing a literature review, I have developed a literature review template for you to use – it’s a huge time-saver and walks you through how to write a literature review step-by-step:

Literature Review Examples

For the following types of literature review, I present an explanation and overview of the type, followed by links to some real-life literature reviews on the topics.

1. Narrative Review Examples

Also known as a traditional literature review, the narrative review provides a broad overview of the studies done on a particular topic.

It often includes both qualitative and quantitative studies and may cover a wide range of years.

The narrative review’s purpose is to identify commonalities, gaps, and contradictions in the literature .

I recommend to my students that they should gather their studies together, take notes on each study, then try to group them by themes that form the basis for the review (see my step-by-step instructions at the end of the article).

Example Study

Title: Communication in healthcare: a narrative review of the literature and practical recommendations

Citation: Vermeir, P., Vandijck, D., Degroote, S., Peleman, R., Verhaeghe, R., Mortier, E., … & Vogelaers, D. (2015). Communication in healthcare: a narrative review of the literature and practical recommendations. International journal of clinical practice , 69 (11), 1257-1267.

Source: https://onlinelibrary.wiley.com/doi/pdf/10.1111/ijcp.12686  

Overview: This narrative review analyzed themes emerging from 69 articles about communication in healthcare contexts. Five key themes were found in the literature: poor communication can lead to various negative outcomes, discontinuity of care, compromise of patient safety, patient dissatisfaction, and inefficient use of resources. After presenting the key themes, the authors recommend that practitioners need to approach healthcare communication in a more structured way, such as by ensuring there is a clear understanding of who is in charge of ensuring effective communication in clinical settings.

• A narrative review on burnout experienced by medical students and residents (Dyrbye & Shanafelt, 2015) – read here

2. Systematic Review Examples

This type of literature review is more structured and rigorous than a narrative review. It involves a detailed and comprehensive plan and search strategy derived from a set of specified research questions.

The key way you’d know a systematic review compared to a narrative review is in the methodology: the systematic review will likely have a very clear criteria for how the studies were collected, and clear explanations of exclusion/inclusion criteria. 

The goal is to gather the maximum amount of valid literature on the topic, filter out invalid or low-quality reviews, and minimize bias. Ideally, this will provide more reliable findings, leading to higher-quality conclusions and recommendations for further research.

You may note from the examples below that the ‘method’ sections in systematic reviews tend to be much more explicit, often noting rigid inclusion/exclusion criteria and exact keywords used in searches.

Title: The importance of food naturalness for consumers: Results of a systematic review  

Citation: Roman, S., Sánchez-Siles, L. M., & Siegrist, M. (2017). The importance of food naturalness for consumers: Results of a systematic review. Trends in food science & technology , 67 , 44-57.

Source: https://www.sciencedirect.com/science/article/pii/S092422441730122X  

Overview: This systematic review included 72 studies of food naturalness to explore trends in the literature about its importance for consumers. Keywords used in the data search included: food, naturalness, natural content, and natural ingredients. Studies were included if they examined consumers’ preference for food naturalness and contained empirical data. The authors found that the literature lacks clarity about how naturalness is defined and measured, but also found that food consumption is significantly influenced by perceived naturalness of goods.

3. Meta-analysis

This is a type of systematic review that uses statistical methods to combine and summarize the results of several studies.

Due to its robust methodology, a meta-analysis is often considered the ‘gold standard’ of secondary research , as it provides a more precise estimate of a treatment effect than any individual study contributing to the pooled analysis.

Furthermore, by aggregating data from a range of studies, a meta-analysis can identify patterns, disagreements, or other interesting relationships that may have been hidden in individual studies.

This helps to enhance the generalizability of findings, making the conclusions drawn from a meta-analysis particularly powerful and informative for policy and practice.

Title: Cholesterol and Alzheimer’s Disease Risk: A Meta-Meta-Analysis

Citation: Sáiz-Vazquez, O., Puente-Martínez, A., Ubillos-Landa, S., Pacheco-Bonrostro, J., & Santabárbara, J. (2020). Cholesterol and Alzheimer’s disease risk: a meta-meta-analysis. Brain sciences, 10(6), 386.

Source: https://doi.org/10.3390/brainsci10060386  

O verview: This study examines the relationship between cholesterol and Alzheimer’s disease (AD). Researchers conducted a systematic search of meta-analyses and reviewed several databases, collecting 100 primary studies and five meta-analyses to analyze the connection between cholesterol and Alzheimer’s disease. They find that the literature compellingly demonstrates that low-density lipoprotein cholesterol (LDL-C) levels significantly influence the development of Alzheimer’s disease.

Other Types of Reviews

• Scoping Review: This type of review is used to map the key concepts underpinning a research area and the main sources and types of evidence available. It can be undertaken as stand-alone projects in their own right, or as a precursor to a systematic review.
• Rapid Review: This type of review accelerates the systematic review process in order to produce information in a timely manner. This is achieved by simplifying or omitting stages of the systematic review process.
• Integrative Review: This review method is more inclusive than others, allowing for the simultaneous inclusion of experimental and non-experimental research. The goal is to more comprehensively understand a particular phenomenon.
• Critical Review: This is similar to a narrative review but requires a robust understanding of both the subject and the existing literature. In a critical review, the reviewer not only summarizes the existing literature, but also evaluates its strengths and weaknesses. This is common in the social sciences and humanities .
• State-of-the-Art Review: This considers the current level of advancement in a field or topic and makes recommendations for future research directions. This type of review is common in technological and scientific fields but can be applied to any discipline.

How to Write a Narrative Review (Tips for Undergrad Students)

Most undergraduate students conducting a capstone research project will be writing narrative reviews. Below is a five-step process for conducting a simple review of the literature for your project.

• Search for Relevant Literature: Use scholarly databases related to your field of study, provided by your university library, along with appropriate search terms to identify key scholarly articles that have been published on your topic.
• Evaluate and Select Sources: Filter the source list by selecting studies that are directly relevant and of sufficient quality, considering factors like credibility , objectivity, accuracy, and validity.
• Analyze and Synthesize: Review each source and summarize the main arguments  in one paragraph (or more, for postgrad). Keep these summaries in a table.
• Identify Themes: With all studies summarized, group studies that share common themes, such as studies that have similar findings or methodologies.
• Write the Review: Write your review based upon the themes or subtopics you have identified. Give a thorough overview of each theme, integrating source data, and conclude with a summary of the current state of knowledge then suggestions for future research based upon your evaluation of what is lacking in the literature.

Literature reviews don’t have to be as scary as they seem. Yes, they are difficult and require a strong degree of comprehension of academic studies. But it can be feasibly done through following a structured approach to data collection and analysis. With my undergraduate research students (who tend to conduct small-scale qualitative studies ), I encourage them to conduct a narrative literature review whereby they can identify key themes in the literature. Within each theme, students can critique key studies and their strengths and limitations , in order to get a lay of the land and come to a point where they can identify ways to contribute new insights to the existing academic conversation on their topic.

How to Write a Literature Review with Examples

Writing a literature review is a necessary and important step in academic research. You’ll likely write a lit review for your Master’s Thesis and most definitely for your Doctoral Dissertation. It’s something that lets you show your knowledge of the topic. It’s also a way to show off yourself as an expert in the area. The literature review establishes the fact that you’ve done your due diligence.

For your reader, it is a good way to communicate just what is out there in terms of existing knowledge about your research topic. The lit review allows you to summarize and assess the current state of research, by bringing together and synthesizing available studies on the matter.

Ultimately, the literature review lets you present a summary of the body of knowledge and use that to identify research gaps that you can then try to fill. It is incredibly helpful in setting up a theoretical framework and justification for your own study.

This guide will help you understand what is a literature review so that you’ll know its value and importance, as well as how to write one effectively.

• Key Takeaways
• A literature review synthesizes existing research, identifies gaps, and establishes a foundation for new studies.
• A clear structure (Introduction, Body, and Conclusion) is essential for effectively presenting findings and insights.

Literature Review FAQ

What is a literature review.

A literature review is a synthesis and critical analysis of research relevant to a specific topic or research question that you have raised for study. It is more than a summary of sources; it is a critical evaluation that weaves together current and past literature to reveal patterns, theoretical insights, research directions, and research gaps.

The main point of a literature review is to show a well-rounded understanding of the state of the topic with regard to existing studies. It helps researchers position their work in the context of what is already known, how it fits, why it is necessary, or how it extends the current understanding.

It also serves to build a solid foundation for further research, by acting as a backdrop against which new research contributions can be made.

Importance of a Literature Review in Academic Research

A literature review is necessary as it will serve several purposes for your research:

• Understanding the Field : First, the literature review provides an overview of the existing body of knowledge, which helps researchers understand the scope of previous studies and what has already been uncovered in the field.
• Identifying Gaps : Second, when they look at existing literature, researchers can more easily identify where research is lacking or where questions remain unanswered. These gaps form the justification for new investigations.
• Critical Analysis : Third, a literature review allows the researcher to critically analyze how previous studies have been conducted, what methodologies were used, what evidence was uncovered, whether they sufficiently addressed the research problem, or what areas of research are still needed.
• Theoretical Framework : Fourth, the literature review acts as support for the development of a theoretical framework with which the research can be conducted and interpreted, as it grounds the study in ideas based existing data.

There are different types of literature reviews for different purposes. Knowing when to use each type will help you shape your own review.

Narrative Review

A narrative review gives an overview of the topic by focusing on the development of theories and concepts over time. It is often descriptive and used when only a brief review is possible. Its weakness is that it lacks the systematic methodology of more structured reviews. However, narrative reviews are useful for obtaining a quick understanding of the topic and where research has focused in the past.

Systematic Review

A systematic review is more rigorous than a narrative review. It has a very methodical approach to searching for and reviewing existing literature. This type of review is characterized by its well-defined research question and a detailed, reproducible methodology that allows for the collection, critical appraisal, and synthesis of all relevant evidence. Inclusion and exclusion criteria are stated. Due to their structured and transparent nature, systematic reviews are particularly prevalent in fields like healthcare and social sciences, where evidence-based conclusions are needed for guiding practice and policy decisions.

The methodology of a systematic review begins with the precise formulation of a research question, which serves as the foundation for the entire review process.

Next, a fully detailed search strategy is developed so that all relevant studies are identified. The researcher will usually require access to multiple databases and literature types (white and grey papers, etc.). The inclusion and exclusion criteria must be explicitly defined to show which studies will be considered and which will be excluded, based on predetermined factors like study design, population, year published, language, and relevance to the research question.

Finally, the data extraction and analysis phase involves systematically gathering data from the selected studies and conducting a detailed analysis, which may include quantitative synthesis (like meta-analysis) or a qualitative assessment of the evidence. This approach allows the researcher to make sure the findings are robust, reliable, and can be replicated in future research.

Theoretical Review

A theoretical review looks at theories relevant to a particular area of study. It focuses on conceptual frameworks that have been developed to explain phenomena, analyze theories’ strengths and limitations, and propose new theoretical approaches if necessary. These reviews are helpful when the research is going to explore or challenge existing theoretical assumptions.

Integrative Review

An integrative review synthesizes existing research to generate new perspectives or frameworks. Unlike systematic reviews, integrative reviews will use both qualitative and quantitative studies and offer a broader analysis of the literature. This type is helpful for researchers who want to develop new and deeper insights and more holistic theories by integrating a wider array of research findings.

Writing a literature review can seem like a lot to take on. However, it is a very manageable process when you break it down into simple steps. Here’s our step-by-step guide on how to write a literature review.

Step 1: Select a Topic

The first step in writing a literature review is to choose a topic that is relevant and interesting to your research field. It should align with your research objectives. It should be specific and focused. Don’t make it too broad—but also don’t make it so narrow that you can’t find any research on it at all. You want there to be ample literature available to review. Your research will build on that.

Tip : Focus on a specific research question that your literature review will address. Try using field relevant keywords when you search ideas in literature databases.

Step 2: Search for Relevant Literature

Once your topic is chosen, conduct a thorough search for academic sources. Use databases like PubMed, JSTOR, or Google Scholar to find peer-reviewed articles, books, and conference papers.

• Use keywords related to your topic.
• Apply filters like publication date and research area.
• Search in libraries, academic journals, and trusted repositories.

Step 3: Evaluate and Analyze the Sources

Not all sources are created equal. Critically evaluate the quality and relevance of the literature. Consider the credibility of the author, the validity of the research methods, and the significance of the findings.

Criteria for Evaluation

• Author’s credentials and publication source
• Research design and methodology
• The study’s contribution to the field

Step 4: Organize the Literature

Organize your sources based on common themes, methodologies, findings, or the chronological development of ideas. A well-structured literature review outline can help. For example, you may categorize studies based on:

• Theoretical concepts
• Methodological approaches
• Historical progression

Organization Tips

• Use thematic or chronological order to maintain a coherent review.
• Identify major trends and seminal works in the field.

Step 5: Write the Literature Review

When writing, strive for a balanced discussion. Do not just summarize; synthesize and analyze. Critique the sources. Discuss the findings in a way that brings information in from multiple studies. Point out agreements, contradictions, and unanswered questions among the various sources.

Writing Tips

• Start each section with a strong topic sentence.
• Use clear and concise language.
• Maintain an objective tone, and do not inject personal opinions.

Literature Review Format

• Introduction: Present your research question and explain the purpose of the review.
• Body: Discuss studies in a structured manner.
• Conclusion: Summarize key findings and suggest future research directions.

A literature review typically follows a standard structure.

Introduction

Introduce your topic and explain the review’s purpose. Clearly define the scope and outline the organization of the review.

The body is where you organize your sources. This can be done thematically (grouping similar studies together) or chronologically (presenting research in order of publication). Integrate studies by discussing their contributions and limitations.

Important Reminders

• Use transition words to maintain a logical flow.
• Highlight influential works and major shifts in the research.

Summarize the insights gained from your review. Highlight research gaps and suggest directions for future study. This section also emphasizes the significance of your research within the broader academic context.

The Impact of Social Media on Adolescent Mental Health

Here is our literature review example to show you how yours can look.

Social media usage among adolescents has sparked concern among mental health professionals (Uhls et al., 2017). Given that young people today are among the most active social media users, it is important to know how these platforms impact their psychological well-being. Adolescents are at a developmental stage where identity and role confusion represent the major conflict of their age according to Erikson’s psychosocial model. Social media platforms provide a space for this dramatic conflict to play out in ways that researchers are still trying to understand (Best et al., 2014).

Numerous studies have explored the relationship between social media engagement and various mental health outcomes (Maktelow & Taylor, 2014; Przybylski et al., 2013; Uhls et al., 2017). However, the findings are often mixed, and show both beneficial and harmful effects. This literature review focuses on the positive aspects of social media, such as peer support, the negative outcomes like heightened anxiety and depression, and the limitations inherent in the methodologies used by these studies.

Positive Impacts of Social Media: Peer Support and Connection

Research on the positive implications of social media for adolescent mental health indicates that these platforms have a lot to do with how social connections are established and the extent to which peer support is obtained (Best et al., 2014). Social media can promote a sense of belonging and provide adolescents with emotional support from their peers (Best et al., 2014). These online interactions can be beneficial for adolescents who experience social isolation or struggle with face-to-face interactions (Uhls et al., 2017). The ability to connect with peers who share similar experiences or interests can give a level of emotional affirmation that traditional offline interactions sometimes lack.

Uhls et al. (2017) described the importance of online communities in providing adolescents with opportunities for social engagement and self-expression, suggesting that these platforms allow teens to seek advice, share personal experiences, and receive encouragement, which can contribute positively to their self-esteem. Adolescents experiencing challenges such as bullying or family issues often turn to social media communities for support and validation, where they feel understood and less alone. In this way, the social connectivity afforded by platforms like Facebook, Instagram, and Snapchat can enhance adolescents’ overall well-being and promote resilience.

Negative Consequences of Social Media: Anxiety, Depression, and Self-Esteem Issues

Even though social media can offer emotional benefits, extensive evidence also points to its potential to harm adolescent mental health. One of the most frequently documented adverse outcomes is increased anxiety and depression linked to excessive social media use (Twenge & Campbell, 2018). Twenge and Campbell (2018) conducted a large-scale study that revealed a correlation between high levels of social media engagement and rising rates of depressive symptoms among teenagers. The researchers argued that the constant exposure to curated and often idealized representations of others’ lives led to feelings of inadequacy, poor self-image, and heightened anxiety. Adolescents may feel pressured to project a perfect image of themselves online, which can be exhausting and detrimental to their self-esteem.

Moreover, the concept of “fear of missing out” (FOMO) has emerged as a significant factor contributing to adolescent anxiety. FOMO refers to the pervasive apprehension that others are having rewarding experiences from which one is absent (Przybylski et al., 2013). Adolescents who experience FOMO are more likely to engage in compulsive social media checking, which disrupts their daily routines, sleep patterns, and academic performance (Przybylski et al., 2013). This behavior creates a cycle of anxiety and stress, as constant comparison and the need to remain connected exacerbate feelings of inadequacy.

Another area of concern is the impact of cyberbullying, which has become increasingly common with the advent of social media. Patchin and Hinduja (2015) found that victims of online harassment are more likely to experience severe psychological distress, like suicidal ideation and self-harm. Unlike traditional bullying, cyberbullying can occur at any time and is often anonymous, making it particularly relentless and damaging. The permanence of online interactions means that harmful content can be shared and viewed repeatedly, amplifying the psychological toll on victims. As a result, the mental health repercussions of cyberbullying can be profound and long-lasting.

Methodological Limitations in Existing Research

Despite the wealth of research on the relationship between social media and adolescent mental health, several methodological limitations complicate the interpretation of findings. One significant challenge is the reliance on self-reported data, which can be subject to bias. Adolescents may not accurately recall or may choose to underreport the extent of their social media use or the severity of their psychological symptoms (Keles et al., 2020). Reliance on self-reported measures makes it difficult to establish causal relationships between social media use and mental health outcomes.

Furthermore, many studies use cross-sectional designs, which cannot determine the directionality of the relationship between social media use and mental health (Patchin & Hinduja, 2015). It remains unclear whether increased social media use leads to poorer mental health or if adolescents struggling with mental health issues are more likely to seek out social media as a coping mechanism. Longitudinal research is needed to better understand the temporal dynamics of this relationship. The heterogeneity of social media platforms also complicates research, as different platforms may have unique features that affect users differently.. For example, visual platforms like Instagram may have a different psychological impact than text-based platforms like Twitter, and few if any studies have accounted for these nuances.

Another limitation involves the cultural context of social media use. Much of the research is conducted in Western countries, primarily the United States and Europe, which may not fully capture the full experience of adolescent social media engagement. Cultural differences in social norms, values, and access to technology can influence how adolescents use social media and how it affects their well-being. Thus, a culturally diverse research approach may be necessary to draw the most applicable conclusions.

The impact of social media on adolescent mental health has positive and negative dimensions. Social media platforms offer adolescents opportunities to seek peer support and partake of social engagement. At the same time there is the risk of excessive use and negative experiences, such as cyberbullying and FOMO, which are linked to increased anxiety, depression, and self-esteem issues. Existing research reveals methodological limitations such as self-reported data, cross-sectional designs, and a lack of cultural diversity in studies. Future research should focus on longitudinal studies and culturally sensitive approaches for a fuller understanding of how social media influences adolescent mental health. Moreover, intervention strategies that teach adolescents healthy social media habits and provide resources for coping with online stressors may be needed.

When writing in APA style, an APA literature review must follow specific guidelines for citation and formatting.

APA Formatting Guidelines

• Title Page : Include the title, author’s name, and institutional affiliation.
• Abstract : A brief summary of your review (usually 150-250 words).
• In-text Citations : Use the author-date citation method (e.g., Smith, 2020).
• Reference List : Provide full citations for all referenced works in alphabetical order.

Tips : Always adhere to the latest APA manual for formatting rules.

A literature review template can simplify the process of organizing your review. You can find templates for APA, MLA, or Harvard formats at Purdue OWL . These templates provide a ready-to-use framework, so that your review is well-structured.

Common Mistakes to Avoid When Writing a Literature Review

Even experienced researchers can fall into common pitfalls. Here’s what to avoid:

• Lack of Focus : Make sure your review addresses a clear research question.
• Poor Organization : Avoid a scattered presentation. Use an outline to maintain structure.
• Failure to Synthesize : Do not just list sources. Instead, integrate and compare studies to show meaningful conclusions.
• Outdated Sources : Always use recent and relevant research unless discussing foundational theories.

How long should a literature review be?

The length depends on the purpose and scope of your study. A literature review for a dissertation is typically longer than one for a research paper.

Can I include non-academic sources in a literature review?

Generally, it’s best to prioritize peer-reviewed and scholarly sources. However, in some cases, reputable non-academic sources may be used to provide additional context.

How do I structure a literature review for a dissertation?

Follow a detailed outline that includes an introduction, a well-organized body (thematic or chronological), and a concise conclusion. Discuss theories, methodologies, and identify research gaps.

120 Fresh and Thought-Provoking Topics for Literature Reviews in Different Disciplines

A literature review is an account of the scholarly works published on a topic. It is different from an annotated bibliography – and far more interesting at that. Instead of being just a list of summaries, a literature review synthesizes the information from all available sources in an overall relationship to your guiding concept. This may be the problem you are discussing, a statement you are arguing, a theory you are verifying, etc.

The goals of a literature review may vary:

• giving a historical overview of the research in the field
• summarizing the existing state of the topic
• finding a problem or a gap in the research field
• developing a new theory, etc.

That is why good literature review topics are often formulated as research questions. This type of paper is not an easy writing. You will need to parse immense volumes of information, synthesize and summarize coherently. You also need to devote plenty of time to reading.

This post contains a list of literature review topics suggested for various subjects. However, when choosing the most fitting one to dig into, ask yourself, what are the passions that you can apply to this research? This assignment will take a while, so you will need more than just a good study discipline to soldier on. A bit of enthusiasm and intrinsic motivation will get you much farther.

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: 

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. 

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. 

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. 

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.

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:

Literature Review – Types Writing Guide and Examples

Table of Contents

A literature review is an essential part of research that surveys existing studies on a topic, providing a foundation and context for new research. It identifies gaps, highlights trends, and establishes a basis for the study’s research questions. This guide explains the types of literature reviews, offers a step-by-step writing guide, and includes examples to help you write a comprehensive and effective review.

Literature Review

A literature review synthesizes and evaluates previous research on a topic. It involves collecting relevant studies, analyzing their findings, and summarizing the knowledge gained. By conducting a literature review, researchers can establish their research within the broader academic conversation, showing how their study builds on or diverges from existing work.

Purposes of a Literature Review :

• Establish Context : Show the current state of research in the field.
• Identify Gaps : Highlight areas that need further investigation.
• Support Research Goals : Provide a foundation for research questions or hypotheses.
• Prevent Redundancy : Avoid duplicating existing studies by understanding what has already been done.

Types of Literature Reviews

1. narrative (traditional) literature review.

• Provides a comprehensive summary of the literature on a topic without a specific research question.
• Commonly used to establish context, it discusses broad themes and trends.
• Example : A narrative review on mental health might cover various treatment approaches and outcomes without a specific focus.

2. Systematic Literature Review

• Involves a structured, replicable process to collect, evaluate, and summarize relevant studies.
• Includes specific criteria for selecting studies and aims to answer a focused research question.
• Example : A systematic review on the effects of cognitive-behavioral therapy on anxiety would detail the selection process, inclusion criteria, and statistical findings.

3. Meta-Analysis

• A subtype of a systematic review that uses statistical methods to combine findings from multiple studies, providing quantitative insights.
• Example : A meta-analysis of studies on the impact of exercise on stress relief might provide an average effect size across all studies.

4. Theoretical Literature Review

• Focuses on evaluating theoretical frameworks, models, and key concepts rather than empirical data.
• Useful for exploring theories that guide research in specific fields.
• Example : Reviewing theories of motivation in education to understand which are most applicable to modern teaching practices.

5. Scoping Review

• Maps the breadth of literature on a broad topic without the rigor of a systematic review.
• Used to identify research gaps and potential areas for future study.
• Example : A scoping review of digital marketing practices in e-commerce might explore various strategies and technologies without evaluating outcomes.

6. Integrative Literature Review

• Integrates and synthesizes both qualitative and quantitative studies to provide a broad understanding of a topic.
• Useful for establishing new theoretical frameworks or identifying broad trends.
• Example : An integrative review on employee engagement could analyze surveys, interviews, and case studies to create a cohesive view of engagement factors.

Writing Guide for a Literature Review

Step 1: define your research scope and purpose.

Start by clarifying the purpose and scope of your literature review. Determine whether you are conducting a broad overview or focusing on specific questions or theories.

Example : “This literature review examines the relationship between social media use and mental health, focusing on how social media impacts self-esteem and anxiety.”

Step 2: Search for Relevant Literature

Use academic databases like PubMed, JSTOR, and Google Scholar to locate relevant articles. Define your search terms and criteria, and prioritize recent studies or key papers in the field.

• Keywords : Use specific keywords and phrases that are central to your topic.
• Inclusion/Exclusion Criteria : Define parameters for the studies you will include, such as publication date, sample size, or methodology.

Example : For a review on employee motivation, keywords might include “employee engagement,” “motivation in the workplace,” and “job satisfaction.”

Step 3: Organize and Summarize Key Themes

Read each study carefully and take notes on significant findings, methodologies, and limitations. Identify recurring themes, patterns, or controversies and organize the literature based on these insights.

Example : Themes in a review on remote work might include productivity, work-life balance, and mental health.

Step 4: Develop an Outline

Structure your literature review to maintain logical flow and readability. A typical outline includes:

• Introduction : Briefly introduce the topic, purpose, and scope of the review.
• Thematic Sections : Divide the review into sections based on themes or research approaches.
• Conclusion : Summarize findings, highlight research gaps, and suggest future research directions.

Example Outline for a Literature Review on Mental Health :

• Introduction
• Impact of Social Media on Self-Esteem
• Social Media’s Role in Anxiety and Depression
• Gaps in the Literature and Future Directions

Step 5: Analyze and Synthesize the Literature

Go beyond summarizing by comparing studies, analyzing their results, and synthesizing insights. Highlight consistencies, contradictions, or unique findings that contribute to a comprehensive understanding of the topic.

Example : Discuss how different studies on cognitive-behavioral therapy report varying levels of effectiveness for depression, based on factors like sample size or intervention duration.

Step 6: Write the Literature Review

Following your outline, write each section of the literature review. Ensure that each paragraph flows logically and builds on previous sections. Use direct quotes sparingly and focus on paraphrasing findings to maintain your narrative.

• Introduction : Present an overview of the topic, importance, and objectives.
• Body : Detail each theme, comparing and contrasting findings.
• Conclusion : Summarize the main findings, acknowledge gaps, and suggest areas for further study.

Step 7: Cite Sources and Format Properly

Use consistent citation style (APA, MLA, Chicago, etc.) and include a reference list of all sources. Proper referencing gives credit to authors and strengthens the credibility of your review.

Example of a Literature Review Excerpt

Title : Literature Review on the Effects of Social Media on Adolescent Mental Health

Introduction Social media has become an integral part of adolescents’ lives, influencing their mental health and well-being. This literature review explores how social media affects self-esteem and anxiety among adolescents, summarizing studies conducted over the past decade.

Social Media and Self-Esteem Several studies have found that social media can have both positive and negative effects on adolescent self-esteem. For instance, Valkenburg and Peter (2019) observed that positive interactions on social media platforms boost self-esteem, while negative comments contribute to lower self-worth. Conversely, a study by Jackson (2020) indicated that adolescents who frequently compare themselves to others on social media report lower self-esteem overall.

Social Media and Anxiety Anxiety is another psychological issue linked to social media use. Research by Smith et al. (2018) suggests that excessive use of platforms like Instagram is associated with increased anxiety levels, particularly among girls. A meta-analysis by Johnson and Allen (2021) revealed a correlation between time spent on social media and higher levels of anxiety, although it acknowledged that causation could not be definitively established.

Conclusion The reviewed studies highlight both the positive and negative impacts of social media on adolescent mental health. However, gaps remain, particularly regarding longitudinal studies that track these effects over time. Future research should focus on examining the long-term psychological effects of social media use to guide effective interventions.

Tips for Writing an Effective Literature Review

• Be Objective : Avoid personal biases and represent the literature fairly.
• Stay Focused : Stick to the main research question and relevant studies.
• Use Clear Transitions : Ensure a logical flow between sections and ideas.
• Critique, Don’t Just Summarize : Analyze and evaluate studies to highlight strengths and weaknesses.
• Revise and Proofread : Ensure clarity, coherence, and consistency in writing style.

Common Mistakes to Avoid

• Over-Reliance on Direct Quotes : Paraphrase to keep your voice consistent.
• Lack of Structure : Use an outline to organize the literature review logically.
• Not Addressing Contradictory Findings : Acknowledge and discuss differing results.
• Ignoring Methodological Differences : Consider how study designs or sample sizes affect findings.
• Failure to Update Sources : Use the most recent and relevant studies to ensure your review is current.

A literature review is a critical component of research that establishes the foundation for your study. By understanding the types of literature reviews and following a structured writing guide, you can create a comprehensive, insightful review that supports your research goals. Whether conducting a systematic review, meta-analysis, or narrative review, a well-crafted literature review not only summarizes existing knowledge but also contributes to academic discourse by identifying research gaps and future directions.
