Literature Review Example: An Annotated Sample You Can Actually Follow
By Jess 10 min read
Here is the truth about literature reviews: nobody learns how to write one by reading instructions alone. You need to see one. You need to see how the sentences connect, how sources get woven together, and how a single paragraph can move from evidence to analysis without breaking a sweat.
That is exactly what this page gives you. Below you will find a real literature review paragraph, fully annotated, plus the patterns and templates you can steal for your own paper. No fluff, no theory-only lectures. Just a concrete example and a clear breakdown.
Why Examples Matter More Than Instructions
Think about it. Your professor hands you a rubric that says "synthesize the literature" and "critically evaluate sources." That sounds great on paper, but what does synthesis actually look like in a finished paragraph?
A good literature review example solves three problems at once. First, it shows you the target. You stop guessing what your professor expects and start seeing the standard. Second, it reveals the internal logic, the invisible moves experienced researchers make without thinking. Third, it gives you a scaffold you can fill in with your own sources.
So let us look at one. If you want the full step-by-step process first, start with our guide to writing a literature review.
Annotated Literature Review Example: Social Media and Adolescent Mental Health
Below is a sample paragraph from a literature review on the impact of social media on adolescent mental health. After the paragraph, callout boxes explain why each part works.
[1] The relationship between social media use and adolescent mental health has emerged as one of the most debated topics in developmental psychology over the past decade. [2] Twenge and Campbell (2018) analyzed two nationally representative surveys covering more than 500,000 adolescents and found that increased screen time was significantly associated with higher rates of depressive symptoms and suicidality, particularly among girls. [3] Similarly, a longitudinal cohort study by Coyne et al. (2020) tracked 500 participants over six years and reported that time spent on social media predicted increased anxiety and loneliness in early adulthood. [4] However, not all evidence supports a straightforward negative relationship. Orben and Przybylski (2019) re-analyzed three large-scale datasets using specification curve analysis and concluded that the association between digital technology use and well-being was negative but trivially small, accounting for less than 0.4% of the variation in well-being. [5] This discrepancy likely reflects differences in methodology: studies relying on self-reported screen time and cross-sectional designs tend to report larger effects than those using objective usage data or longitudinal frameworks (Odgers & Jensen, 2020). [6] Taken together, the current evidence suggests that the impact of social media on adolescent mental health is real but modest, and that future research must move beyond total screen time to examine specific activities, such as passive scrolling versus active communication, to produce actionable findings for clinicians and educators.
Note: Author names and findings above are illustrative. Always verify citations against original sources.
[1] Topic Sentence
Opens with the big-picture claim. It names the specific relationship under review and signals its importance. Notice it does not cite a source yet. The topic sentence is your framing, not someone else's.
[2] First Piece of Evidence
Introduces the strongest supporting study. Notice the specifics: the method (two national surveys), the sample size (500,000+), and the key finding. Vague summaries like "studies show" kill credibility. Concrete details build it.
[3] Corroborating Evidence
"Similarly" signals this study points in the same direction. A second source with a different design (longitudinal cohort) strengthens the argument. This is synthesis: grouping sources that agree and showing why they agree.
[4] Counter-Evidence (Critical Analysis)
"However" pivots to a contradicting study. This is where most student papers fall flat. They only present sources that agree. Including counter-evidence and engaging with it shows critical thinking, which is exactly what reviewers look for.
[5] Methodological Explanation
Instead of leaving the contradiction hanging, this sentence explains why the studies disagree. Comparing methodologies (self-reported vs. objective data, cross-sectional vs. longitudinal) is one of the highest-value moves in a literature review. It shows you understand the research, not just the results.
[6] Synthesis and Transition
"Taken together" pulls all the threads into a single, balanced conclusion. It also points forward, naming a specific gap (passive scrolling vs. active communication) that sets up the next section of the review. Never end a paragraph in a dead end.
The Four-Part Structure Inside Every Strong Paragraph
Look at that example again. Every high-scoring literature review paragraph follows the same underlying structure, even when the topic changes completely.
- Topic sentence. State the claim or theme this paragraph will address. Use your own voice. Do not open with a citation.
- Evidence synthesis. Present two or three sources that speak to the same point. Group them by agreement, methodology, or chronology. Include concrete details (sample size, design, key finding).
- Critical analysis. Introduce disagreement or limitations. Explain why findings differ. Compare methods, populations, or theoretical frameworks.
- Transition. Wrap up with a balanced takeaway and bridge to the next paragraph or section. Identify a gap, raise a question, or narrow the focus.

1. Group by Theme, Not by Source
The most common mistake in student literature reviews is the "source-by-source" approach: "Smith (2019) found X. Jones (2020) found Y. Lee (2021) found Z." That is a reading list, not a review. Instead, organize each paragraph around a theme or argument, then pull in multiple sources to support it. The example above organizes around the theme of effect size, not around individual papers. This thematic approach is also the most common structure in narrative literature reviews vs systematic reviews.
2. Compare Methodologies
When two studies disagree, do not just report the disagreement. Dig into why they disagree. Was one cross-sectional and the other longitudinal? Did one use self-reported data while the other used app-tracked usage? Explaining methodological differences is one of the fastest ways to show your professor you actually read the papers, and it almost always earns higher marks.
3. Identify and Name the Gap
Every literature review exists to justify your research question. The best way to do that is to explicitly name what the existing research has not done. In the example, the gap is the lack of research on specific social media activities. Naming the gap creates a logical bridge from your review to your methodology section.
Copy-Paste Template for Your Literature Review Paragraph
Use this template the next time you sit down to write a literature review paragraph. Fill in the brackets with your own content.
[Theme/claim this paragraph addresses]. [Author, Year] [method and sample] found that [key finding]. Similarly, [Author, Year] [different method or population] reported [corroborating result], suggesting that [brief synthesis of what these studies share]. However, [Author, Year] challenged this view by [contrary finding or methodological critique]. This discrepancy may reflect [explanation: different methods, populations, definitions, or timeframes]. Taken together, the evidence indicates that [balanced conclusion]. Further research is needed to [specific gap], which is the focus of the present study.
