A literature review is a critical analysis of existing scholarly literature on a particular topic. It is often required as part of academic assignments, such as research papers, theses, and dissertations. However, writing a good literature review can be challenging, especially for first-time students.
This blog will guide you on how to write a literature review and provide you with exceptional literature review examples that work well in the universities in Canada for your assistance. Let’s get started.
What Is A Literature Review?
Purpose Of A Literature Review
The purpose of a literature review is to:
- Demonstrate your knowledge of the existing literature on your topic.
- Identify the key themes, debates, and gaps in the literature.
- Position your own research in the context of the existing literature.
- Show how your research will contribute to the field.
How To Write A Literature Review Example
Writing a literature review involves a systematic and organized approach. Follow the research paper format stated by your organization. Here’s a step-by-step guide to help you write an effective literature review:
Step 1: Define The Scope And Purpose
- Clearly define the research question, thesis statement, or topic you want to address in your literature review.
- Determine the scope of your review by setting boundaries for the time period, geographic location, and specific aspects of the topic you want to cover.
- Identify the purpose of your literature review, such as providing an overview, identifying gaps in existing research, or evaluating the current state of knowledge.
Step 2: Conduct A Comprehensive Literature Search
- Use academic databases, library catalogues, and search engines to find relevant literature. Common databases include PubMed, Google Scholar, and specialized databases related to your field.
- Use a combination of keywords and controlled vocabulary to refine your search.
- Keep track of the sources you find, including bibliographic information, abstracts, and key findings.
- Read professionally written examples of literature review for better understanding.
Step 3: Evaluate And Select Sources
- Critically evaluate the quality and relevance of each source. Consider the credibility of the author, the publication venue, and the methodology used in the studies.
- Organize the selected sources into themes or categories based on commonalities and differences.
- Identify key theories, concepts, or methodologies that are central to your topic.
- For example, in a finance thesis, add sources that are only relevant to the specific topic of finance that you wish to explore.
Step 4: Synthesize Information
- Summarize the main findings and arguments of each source, highlighting key themes and trends.
- Identify areas of agreement and disagreement among the sources.
- Organize the information in a logical and coherent manner. You can use a chronological, thematic, or methodological approach, depending on the nature of your literature review.
Step 5: Write And Revise
- Start with an introduction that provides context for your literature review and clearly states the research question or purpose.
- Organize the body of your literature review based on the themes or categories you identified during the synthesis.
- Discuss each source in relation to your research question, highlighting key findings and their implications.
- Conclude by summarizing the main contributions of the literature to your research question and identifying any gaps or areas for future research.
- Revise and edit your literature review for clarity, coherence, and conciseness.
APA Literature Review Example
Whether you are writing a literature review in APA or MLA, follow the guidelines provided on the websites. Here is a comprehensive example of a literature review in APA that will provide a better understanding of how to write a literature review.
Types Of Literature Review
There are several types of literature reviews, each serving different purposes and objectives. Here are some common types:
Narrative Or Traditional Literature Review
- Provides a comprehensive overview of the existing literature on a particular topic.
- Summarizes and synthesizes information from various sources without a specific methodological approach.
Systematic Literature Review
- Follows a systematic and structured approach to identify, analyze, and synthesize relevant literature.
- Involves a clearly defined research question and a detailed search strategy.
- Aims to minimize bias and subjectivity in the selection and analysis of studies.
Systematic Literature Review Example
- A specialized form of systematic review that involves statistical analysis of quantitative data from multiple studies.
- Combines results from different studies to derive overall conclusions or effect sizes.
- Requires homogeneity in study design and outcome measures for accurate analysis.
- Meta-synthesis is a qualitative approach that synthesizes findings from multiple qualitative studies.
- Involves the interpretation and integration of themes, concepts, or qualitative data across different studies.
- A preliminary literature review on a broad topic to identify key concepts, gaps, and research areas.
- Provides an overview without necessarily synthesizing the evidence.
Scoping Literature Review Example
- Evaluates and critiques the strengths and weaknesses of existing literature.
- Focuses on the methodology, theoretical framework, and overall quality of the studies reviewed.
- Aims to provide a comprehensive understanding of a topic by integrating findings from different types of studies (quantitative, qualitative, or both).
- May include a range of research designs and methodologies.
- Conducted within a shorter timeframe, often for decision-making purposes.
- Involves a streamlined review process with limitations in terms of depth and comprehensiveness.
- A review of existing systematic reviews and meta-analyses on a specific topic.
- Provides a higher level of evidence synthesis by examining the findings of multiple reviews.
Mixed Methods Review
Incorporates both quantitative and qualitative research studies to gain a comprehensive understanding of a research question.
The literature review we write have:
- Precision and Clarity
- Zero Plagiarism
- High-level Encryption
- Authentic Sources
Tips For Writing A Good Literature Review
Here are a few additional tips for writing a good literature review in a dissertation or thesis:
Tip 1: Start Early
Do not wait until the last minute to start writing your literature review. It takes time to do a good job.
Tip 2: Read Widely
Do not just read the most recent articles on your topic. Be sure to read older articles as well.
Tip 3: Take Breaks
Do not try to write your literature review all at once. Take breaks to avoid getting burned out.
Tip 4: Get Feedback
Ask your professor or a classmate to read your literature review and give you feedback.
Common Mistakes To Avoid When Writing A Literature Review
While literature review examples can provide valuable guidance, it is equally important to be aware of common pitfalls that can undermine the effectiveness of your literature review.
- Lack of Focus: A literature review should have a clear focus and not attempt to cover an entire field. Define the boundaries of your review and concentrate on the most relevant and recent literature.
- Overreliance on Secondary Sources: While reviews of existing reviews can be informative, relying solely on secondary sources, such as newspapers, may lead to a lack of depth in your analysis. Strive to include primary research studies to strengthen the credibility of your literature review.
- Failure to Synthesize: Merely summarizing individual studies without synthesizing their findings can result in a disjointed and unconvincing literature review. Connect the dots between different sources to provide a cohesive narrative.
- Ignoring Contradictory Evidence: A robust literature review acknowledges and addresses conflicting findings in the existing literature. Ignoring contradictory evidence can weaken the overall credibility of your review.
