Literature Review – How to
What is a Literature Review
A literature review serves as a comprehensive and critically assessed summary of existing research focused on a specific topic or question. The primary aim is to provide a thorough overview, analysis, and evaluation of current research, pinpointing gaps, identifying trends, resolving conflicts, or highlighting areas warranting further investigation.
Systematically examining scholarly works, including articles, books, theses, and other authoritative sources, a literature review synthesizes the present state of knowledge on the selected subject. This synthesis is essential to establish the relevance of existing research to your project.
Beyond being a mere summary, a literature review showcases your understanding of the published material related to your research question. It illustrates your ability to synthesize existing knowledge, forming a cohesive perspective on the subject.
The literature review analysis and synthesis goes beyond a simple aggregation of information; it involves a nuanced analysis of research findings from authoritative and credible authors.

Writing a literature review is a crucial academic skill that involves systematically examining existing research on a specific topic. A well-crafted literature review not only summarizes relevant literature but also analyzes, evaluates, and synthesizes the information, providing a foundation for further research.
Here are steps to follow to write a literature review:
Step 1: Define your Research Question
Clearly define the scope and focus of your literature review. What specific research question or topic will you address?
Set the purpose of your literature review. Are you aiming to identify gaps in existing research, evaluate methodologies, or provide a comprehensive overview?
Step 2: Develop your Search Strategy
Develop a search strategy to identify relevant sources.
Use keywords, phrases, advanced search operators to refine your search strategy.
Document your search strategies and results, keeping a record of effective strategies aids future searches, saving valuable time.
Step 3: Shortlist Relevant Sources
Use the library catalogue to find sources to answer you research question.
Read abstracts and the skim titles to narrow your source selection.
Create a shortlist of articles for your review.
Step 4: Evaluate the Source Shortlist
Create an annotated bibliography to refine and evaluate your shortlist.
Skim-read each source to make notes that describe content and evaluate the article.
Consider factors like the intended audience, study purpose, recentness, sponsorship, independence of researchers, and any observed limitations.
Step 5: Take & Organise Your Notes
Read and make notes in your own words, summarizing the key findings, arguments, and methodologies of each source. Take note of the main themes and concepts.
Focus on key themes, theories, methodologies, research gaps, weak methodologies, contradictory evidence, and any biases present.
Organize your notes based on one of four approaches: chronological, methodological, thematic, or theoretical framework.
Step 6: Write Your Review
Analyze the strengths and weaknesses of each source. Evaluate the reliability and validity of the research.
Synthesize the information from various sources to develop overarching themes or concepts. Discuss how each source contributes to the overall understanding of the topic.
Write your literature review in a coherent and organized manner. Clearly present the information, ensuring a smooth flow between different sources and ideas.
When to write a Literature Review
A literature review is an integral step for students advancing beyond a basic understanding of a topic. It is typically done as part of the research process when working on academic assignments, research projects, or scholarly articles.
Before embarking on any original research, students must conduct a literature review. This crucial step allows them to assess opportunities, identify gaps, and reconcile contradictory evidence within the existing body of knowledge.
In essence, a literature review serves as the intellectual foundation, guiding students as they navigate the landscape of their chosen subject, ultimately leading them towards contributing meaningfully to their academic field.
Literature reviews are commonly found in academic research papers, theses, dissertations, and scholarly articles.
Here are some common scenarios when you might need to write a literature review:
Original research: Before embarking on your own research, it's essential to review existing literature to understand what is already known and identify gaps or areas for further exploration.
Thesis or dissertation: Literature reviews are a crucial component of more extensive research projects, helping situate your work within the broader scholarly conversation.
Essays and papers: In academic writing, especially at higher education levels, instructors may require literature reviews as part of assignments. This helps students demonstrate their understanding of existing research on a topic.
Systematic review: In fields like medicine and social sciences, researchers may conduct systematic reviews, which involve a comprehensive analysis of existing literature on a specific topic.
Benefits of writing a Literature Review
A literature review offers a multitude of benefits, making it a crucial element in academic research and scholarly endeavors.
