A literature review is a critical component of academic writing across all fields, but its approach can vary significantly depending on the subject. Whether you’re delving into the hard sciences, social sciences, or humanities, each discipline has its own expectations and methodologies for conducting a literature review. In this article, we will explore ten literature review examples across diverse fields to give you a clearer understanding of the varying approaches. This will help you learn how to structure and write your own review, regardless of the subject matter.
What is a Literature Review?
Before we dive into examples, it’s essential to understand what a literature review is and why it’s crucial to academic research. A literature review is a comprehensive survey of existing research on a particular topic, summarizing key findings and providing critical analysis of the material. It’s not just a simple summary of past work—it’s an analysis of the trends, debates, and gaps in the research, offering a foundational context for new research.
The purpose of a literature review is twofold: first, it allows you to demonstrate your understanding of a field; second, it identifies areas for further investigation. This process also ensures that your research builds upon the work that has already been done, avoiding duplication and adding value to the existing body of knowledge.
Why Literature Reviews Differ by Field?
While the structure and purpose of a literature review remain consistent, the content and focus can vary depending on the discipline. This section will explore why literature reviews differ across fields.
Each academic discipline has different conventions regarding how research is presented and analyzed. For instance, the hard sciences often prioritize empirical data and experimental results, whereas the humanities might focus on theoretical frameworks and cultural critiques. Additionally, fields like business or economics might incorporate case studies, trends, and statistical analysis.
Field-specific expectations dictate how you approach the literature review process. In some fields, such as engineering, the review might emphasize technical details and advancements in technology. Meanwhile, in sociology, literature reviews may be centered around theories, methodologies, and social trends. Understanding these distinctions will help you tailor your review to the expectations of your specific discipline.

A medical literature review might follow a systematic review approach, which involves gathering all relevant studies and analyzing them for quality and consistency. This method ensures that the findings are robust and can be used to inform clinical decisions. The review might also discuss the limitations of current treatments and highlight areas for further research.
Example 2: Environmental Science
Literature reviews in environmental science focus on synthesizing research on environmental issues and solutions. Researchers may look into the impact of human activities on climate change, biodiversity, or resource management. An example could be a review of climate change’s effects on biodiversity, examining how rising temperatures have influenced species migration and extinction rates.
In environmental science, reviews often employ a combination of qualitative and quantitative data. Researchers may use meta-analyses to aggregate results from multiple studies and provide a more comprehensive picture of environmental trends. The focus tends to be on synthesizing large datasets and evaluating the effectiveness of conservation strategies.
Example 3: Physics and Engineering
In physics and engineering, literature reviews often examine theoretical foundations and technological advancements. A review in this field might explore the development of renewable energy technologies, such as solar panels, wind turbines, or battery storage systems. It would summarize the key innovations, compare performance metrics, and discuss challenges that remain unsolved.
Such a review would likely incorporate technical data and mathematical models to assess the feasibility of these technologies. The focus is usually on empirical findings and their application to real-world problems. The review could also compare different approaches or solutions and identify gaps in research that need to be addressed.
Literature Review Examples in the Social Sciences
Example 4: Psychology
Psychology literature reviews are crucial for understanding theories of behavior, cognition, and mental health. For instance, a review of cognitive-behavioral therapy (CBT) for anxiety disorders would look at various studies that measure the effectiveness of CBT in treating patients with generalized anxiety disorder, social anxiety disorder, and other related conditions.
Psychology reviews tend to focus on both theoretical frameworks and empirical evidence. Researchers synthesize various treatment approaches, assess their efficacy, and identify the most successful interventions. In addition, these reviews often highlight the underlying psychological mechanisms that explain why certain therapies work.
Example 5: Sociology
Sociology literature reviews often address societal structures, relationships, and the effects of culture and policy. An example might be a review of social media’s impact on youth behavior, exploring how platforms like Instagram or TikTok influence self-esteem, body image, and mental health.
Sociology reviews often incorporate qualitative studies, such as interviews or ethnographies, alongside quantitative research. This mixed-methods approach allows for a more comprehensive understanding of social phenomena, as researchers can explore both statistical trends and individual experiences.
Example 6: Education
Literature reviews in education explore teaching methods, curriculum development, and student outcomes. For example, a review on remote learning effectiveness during the COVID-19 pandemic would assess the impact of online education on student performance, engagement, and mental health.
In education, reviews often compare different instructional strategies, such as traditional classroom learning versus online learning, and evaluate their effectiveness. The review might also look at the influence of socio-economic factors on educational outcomes and identify areas for improvement in current teaching practices.
Literature Review Examples in the Humanities
Example 7: History
History literature reviews often synthesize primary and secondary sources to explore historical events and narratives. A review on the causes of the French Revolution, for instance, would analyze various scholarly interpretations, discussing economic, political, and social factors that contributed to the uprising.
In history, the focus is typically on the historiography—the way historians interpret and write about the past. A history literature review will highlight differing perspectives on key events and offer insights into how historical narratives evolve over time.
Example 8: Philosophy
In philosophy, literature reviews critically engage with foundational texts and philosophical debates. For example, a review of existentialism in 20th-century philosophy might examine key figures like Sartre, Heidegger, and Camus, analyzing how their ideas shaped existentialist thought.
