Writing an effective literature review is a prerequisite to publishing a quality scholarly article. Vital in academic publishing, literature reviews provide essential background context by summarizing existing work in the field and identifying gaps or inconsistencies in the literature.
A well-written literature review establishes the relevance of the research by showing how it builds upon and contributes new insights to the existing body of knowledge.
What is a Literature Review?
A literature review is an overview of key theories, concepts, definitions, methodologies, findings and debates published by researchers and scholars. A literature review surveys scholarly articles, books, dissertations, conference proceedings and other resources relevant to a particular area of research.
In journal publishing, the literature review appears near the beginning, generally after the introduction. The review provides a framework for establishing the importance of the research problem and situating the author’s study within existing knowledge, giving rise to the importance of writing an effective literature review.
Importance of Writing an Effective Literature Review
Writing an effective literature review is essential for several key reasons:
- It demonstrates your expertise and knowledge of the field by highlighting seminal works and major themes or perspectives.
- It provides context and background information needed to understand the research problem and rationale for the study.
- It identifies gaps, inconsistencies and unanswered questions in prior research to justify the need for new research.
- It synthesizes and evaluates previous work to reveal similarities, differences, and relationships between studies.
- It establishes the scholarly significance and relevance of the research problem.
In summary, an effective literature review demonstrates your grasp of the field and convinces readers of the importance and timeliness of the research study.
Understanding the Purpose of a Literature Review
A literature review is vital in academic publishing by synthesizing previous scholarly works related to the research topic or question. By reviewing and analyzing existing literature, researchers can identify gaps, inconsistencies, and contradictions in the current state of knowledge. This process enables them to establish a firm foundation for advancing new insights and perspectives through their original research.
Conducting a rigorous review of prior literature demonstrates that researchers have a comprehensive grasp of the key concepts, theories, findings, and debates that have shaped the topic area. This helps establish the background and rationale for the new study. Situating one’s work within the broader scholarly dialogue lends credibility and helps highlight the unique contributions the new research will make.
An effective literature review contextualizes the research topic and research problem. It shows readers how the new study builds upon, integrates, and departs from previous works. Rather than simply summarizing sources, you need to take a critical and analytical perspective to highlight relationships between different works, reveal areas needing further exploration, and identify promising avenues for future inquiry.
In addition to justifying the need for the present study, the literature review also informs the development of the theoretical framework, methodology, and data analysis plan. You can design the study by thoroughly reviewing established constructs, measures, and analytical techniques to draw from and expand the existing knowledge base. This further strengthens the validity and scholarly merit of the research.
Overall, a well-executed review of prior literature is invaluable for positioning new research within the landscape of existing knowledge. It demonstrates your grasp of the field and ability to integrate and synthesize large amounts of information. A thoughtful literature review establishes a solid empirical and theoretical foundation upon which to build new insights and make substantive contributions to the advancement of knowledge.
Identifying Relevant Literature
Conducting a thorough literature review requires casting a wide net to identify all relevant prior research on your topic. Here are some tips for finding pertinent sources:
Search Academic Databases
Databases like Google Scholar, Web of Science, and PubMed allow you to search thousands of reputable journals and publications simultaneously. The key is looking for recent, highly cited articles to ensure you find essential, up-to-date research.
Scan Reference Lists
Check the reference lists from articles you’ve already found. Authors typically cite the most meaningful prior research in their field, so tracing these connections backwards can uncover additional relevant sources.
Leverage Citation Indexes
Top journal databases allow you to see all the papers that have cited a particularly relevant article. This forward-tracing of citations helps you identify newer publications building on important earlier work.
Bibliographies from books and review articles in your area can point you to significant primary literature. These curated lists help surface foundational references you don’t want to miss.
Talk to Experts
Speaking with professors and researchers in your niche can provide personalized guidance on seminal publications and new developments they recommend reviewing, boosting your confidence in writing an effective literature review.
Manage Your Search
Use reference management software like EndNote or Zotero to organize your search results. Recording your search strategies will help you track where you’ve already looked.
Casting a broad net across multiple sources ensures you gather the most relevant background literature possible. This comprehensive approach is foundational to a rigorous, high-quality review.
Evaluating and Selecting Sources
In writing an effective literature review, it is essential to carefully evaluate and select the most relevant and reliable sources to include. Here are some critical criteria to consider when assessing the literature:
Reliability and Credibility of Sources
Focus on choosing sources from reputable, peer-reviewed journals and academic publishers. Be wary of citing websites, news articles, or other sources that may present biased or inaccurate information. Verify the author’s credibility by reviewing their qualifications and other publications.
Relevance to Your Research Topic
Closely evaluate how applicable each source is to your specific research aims and questions. Seek out literature that directly relates to your topic and aims to fill the knowledge gaps you have identified. Sources that are only peripherally related should be avoided or minimized.
Recency of Sources
When conducting a literature review, it is generally best to prioritize sources published within the last 5-10 years. This ensures your review covers the most current knowledge and findings in the field. Older sources may only be relevant if they represent seminal or landmark studies.
Analyze the methodology used in quantitative or qualitative studies to ensure the findings are based on rigorously designed research. Sources utilizing small sample sizes, flawed designs, or limited data should be excluded when higher-quality options are available.
Pay more attention to sources highly cited within the academic literature, which indicates they have strongly influenced thinking in the field. Databases such as Scopus and Web of Science allow you to view citation counts. However, also ensure sources align with the above criteria.
By systematically evaluating the literature using these criteria, you can select the most high-quality and relevant sources to include in your review. This strengthens the credibility and impact of your work.
Organizing Your Literature Review
When organizing your literature review, categorize and structure the sources you have identified logically. This helps establish a coherent flow and aids the reader in understanding how the sources relate to one another. There are several common organizational patterns used in literature reviews:
With this approach, sources are organized based on the publication date, starting with the earliest relevant studies and ending with the most recent. This allows you to demonstrate how the research has evolved and highlight seminal or landmark studies.
Here, sources are grouped by overarching themes or topics. For example, you may organize by theory, methodology, geographical location of the research, etc. This helps the reader see how different researchers have approached the same topic. Ensure a logical flow between themes and use transitional phrases to guide the reader through each.
In this case, studies using similar research methods are grouped, such as all qualitative studies in one section, quantitative studies in another, etc. This approach highlights differences in results based on the methods used. Be sure to explain why you chose this organizational pattern.
With this structure, you categorize sources by concepts or ideas such as assumptions, definitions, models, factors, variables, etc. You may have a section on conceptual frameworks, one on key variables, and another on hypotheses tested. This shows how researchers have conceptualized the topic differently.
In most cases, literature reviews use a combination of organizational patterns. For instance, you may use chronology within each thematic section. Regardless of the specific approach, the organization should emphasize key contributions and relationships between sources. Use transitions and topic sentences to guide readers through each section and tie the review together as a cohesive whole.
Writing the Literature Review
When writing the literature review section of a journal article, it is vital to provide clear and concise summaries of each source you have selected. Here are some tips for effectively summarizing your sources:
Focus on the Main Points
Do not try to cover every detail or finding from a study. Instead, highlight the main objective, methodology, key results, and conclusions. Identify the most relevant points to your research aims.
Avoid directly quoting long passages from your sources. Paraphrase important information in your own words instead. This demonstrates your understanding and allows you to condense complex details.
Aim to present each source objectively, even if you disagree with the methods or conclusions. You can critique limitations or biases later in the discussion section. In the literature review, stick to neutral and balanced descriptions.
Link summaries together with transitional phrases like “Similarly,” “In contrast,” or “Meanwhile.” This shows the relationships between different sources and highlights areas of agreement vs. disagreement.
Properly cite each source using the specified citation style, e.g., Chicago Manual of Style, APA Style, etc. This allows readers to locate the original articles if desired. Accuracy and attribution are critical.
Check for Clarity and Conciseness
Once you have summarized each source, read through the entire literature review section. Make sure your writing is clear, flows logically, and concisely captures the essence of each study. Refine wording as needed.
By following these tips, you can write literature review summaries that are informative, focused, well-structured, and reflect an objective perspective. This provides a solid foundation for the remaining sections of your journal article.
Editing and Proofreading Your Literature Review
After completing the first draft of your literature review, it is crucial to revise, edit, and proofread your work. A polished literature review is clear, coherent, and error-free. Following these strategies will help you achieve that goal.
Revise for Clarity and Coherence
Critically evaluate the ideas’ structure and logical flow when revising your draft. Make sure your literature review tells a clear, cohesive story by:
- Checking that the content is organized logically, with smooth transitions between topics.
- Verifying that each paragraph has a distinct purpose and focus.
- Assessing whether discussions of sources flow well from one to the next.
- Confirming that the review builds toward your research rationale.
Also, examine your language and style – simplify wording, reduce repetition, and break up long, dense paragraphs to improve readability.
Careful proofreading allows you to catch and correct any remaining writing issues, including:
- Grammatical, punctuation, and spelling errors.
- Incorrect citations or formatting issues.
- Lack of clarity or readability issues.
- Minor inconsistencies in terminology or style.
To proofread effectively:
- Read the review aloud to catch awkward phrasing.
- Check citations and references against the sources.
- Have a colleague review your work to provide feedback.
- Take a break before doing a final read-through.
Investing time to refine your literature review will result in a polished, scholarly overview of previous research – an invaluable part of your journal article.
