Introduction
Writing a dissertation is a monumental task, and one of the most crucial components is the literature review. But what exactly makes this section so important? Simply put, a literature review provides the foundation for your research, offering a comprehensive overview of what has already been done in your field and highlighting the gaps your work aims to fill.
Understanding What a Literature Review Is
Definition
A literature review is a scholarly analysis of the existing research on a particular topic. It involves summarising, evaluating, and synthesising the existing body of knowledge to provide context for your research.
Types of Literature Reviews
There are several types of literature reviews, including:
-
Narrative Literature Review: Provides a comprehensive overview of the existing research.
-
Systematic Literature Review: Focuses on a specific research question, using systematic methods to collect and analyse data.
-
Meta-analysis: Combines the results of multiple studies to arrive at a single conclusion.
The Purpose of a Literature Review in a Dissertation
Contextualising Your Research
A well-conducted literature review helps to contextualise your research within the larger body of work. It demonstrates your understanding of the field and shows how your research contributes to ongoing debates and developments.
Identifying Gaps in Existing Research
By reviewing the literature, you can identify gaps or areas where further research is needed. This justifies your study and positions it as a necessary addition to the field.
Planning Your Literature Review
Setting Objectives
Before diving into the literature, set clear objectives for your goal. This could be understanding the current state of research, identifying critical theories, or finding methodological approaches.
Creating a Timeline
A literature review can be time-consuming, so create a timeline to manage your tasks effectively. Allocate specific periods for searching, reading, organising, and writing.
Finding Relevant Literature
Using Academic Databases
Academic databases like JSTOR, PubMed, and Scopus are invaluable resources. They offer access to peer-reviewed journals, conference papers, and other scholarly materials.
Leveraging Google Scholar
Google Scholar is a free, user-friendly alternative to academic databases. It can help you find many scholarly articles, theses, books, and conference papers.
Organising Your Sources
Reference Management Software
Tools like EndNote, Mendeley, and Zotero can help you manage your references efficiently. They allow you to store, organise, and format citations automatically.
Manual Organization Techniques
If you prefer a hands-on approach, organise your sources manually using spreadsheets or note cards. This method can be effective for visual learners who benefit from physically handling their materials.
Critical Reading and Note-Taking
Identifying Key Themes and Arguments
As you read, identify key themes and arguments. Note how different authors approach the same topic and where they agree or disagree.
Annotating Effectively
Annotate your sources with summaries, key points, and personal reflections. This will help you keep track of important information and make the writing process more manageable.
Analysing and Synthesizing Information
Comparing Different Sources
Compare and contrast different sources to see how they relate to each other. Look for patterns, contradictions, and emerging trends.
Developing Your Argument
Use the insights gained from your analysis to develop your argument. Your literature review should explain why your research is necessary and how it will contribute to the field.
Structuring Your Literature Review
Common Structures
Common structures for a literature review include thematic, chronological, and methodological approaches. Choose the one that best suits your research question and objectives.
Creating an Outline
Create a detailed outline to organise your thoughts and ensure a logical flow in your literature review. This will make the writing process more straightforward and coherent.
Writing the Introduction of Your Literature Review
Setting the Scene
Begin your literature review with an introduction that sets the scene. Provide background information on your topic and explain the purpose of your review.
Highlighting the Importance of Your Research
Clearly state why your research is essential. Highlight the gaps in the existing literature and explain how your work will address them.
Writing the Main Body of Your Literature Review
Thematic Organization
Organise the main body of your literature review thematically. Group related studies together and discuss their findings with each other.
Chronological Organization
Alternatively, you can organise your literature review chronologically. This approach is helpful if you want to show research development over time.
Writing the Conclusion of Your Literature Review
Summarising Key Findings
In your conclusion, summarise the key findings from your literature review. Highlight the most important studies and their contributions to the field.
Linking to Your Research
Link the findings of your literature review to your research. Explain how your study will build on the existing knowledge and address the identified gaps.
Editing and Proofreading Your Literature Review
Checking for Coherence and Flow
Ensure your literature review has a logical structure and flows smoothly from one section to the next. Each paragraph should transition seamlessly into the next.
Grammar and Style Tips
Pay attention to grammar and style. Use clear, concise language and avoid jargon. Proofread your work to eliminate any errors or inconsistencies.
Common Mistakes to Avoid
Over-reliance on One Source
Avoid relying too heavily on one source. A diverse range of references shows a thorough understanding of the literature and strengthens your review.
Lack of Critical Analysis
Refrain from summarising sources; critically analyse them. Discuss their strengths and weaknesses and how they contribute to your understanding of the topic.
Conclusion
Conducting a thorough literature review is critical to writing a successful dissertation. By following these steps, you can create a comprehensive and insightful review that sets the stage for your research. Remember to plan your review, find and organise your sources, read critically, and write clearly. With careful attention to detail and a systematic approach, your literature review will be a solid foundation for your dissertation.
FAQs
How long should my literature review be?

What should I do if I need help finding enough literature on my topic?
If literature on your topic is scarce, broaden your search to include related areas. You can also discuss the lack of literature as a gap your research will address.
How often should I update my literature review?
