A Thorough Guide to Crafting and Organizing Literature Reviews for Research Success

What is a Literature Review (LR)?

A literature review (LR) is a comprehensive examination of existing online or print literature—such as papers, pamphlets, and articles—relevant to your research topic. It is an objective summary of the current knowledge in the field, and it does not include your personal opinions. Instead, the focus is on reviewing and analyzing recent literature, typically from the last five years, that is closely aligned with your research.

In a literature review, your task is to summarize the key findings and then reorganize and synthesize this information. This process may involve comparing older literature with more recent studies to provide a thorough understanding of the topic. By critically evaluating these sources, you present your audience with relevant insights and developments in the field.

Literature reviews are commonly written for scientific papers, though they are also used in humanities research. In some cases, a literature review can stand alone as a scholarly paper, providing a detailed overview of a specific area of study.

A Signpost of Credibility:

Literature reviews (LRs) serve as a crucial guidepost for specific subjects, offering a valuable resource for understanding and navigating a particular topic. By compiling and analyzing existing research, LRs keep professionals updated with the latest developments in their field. A well-conducted literature review not only provides a comprehensive overview of the topic but also reflects the author’s expertise and scholarly rigor, enhancing their credibility. In many scientific disciplines, an in-depth literature review is essential, as it demonstrates the author’s thorough understanding of the subject and their ability to critically engage with existing research.

How Does a Literature Review Differ from Other Writing?

An academic research paper typically presents a new argument, with the literature review (LR) serving as one of its key components. Unlike other sections of a research paper, the LR does not introduce original ideas but rather summarizes and reorganizes existing information to support the new research. Its purpose is to provide a solid foundation by reviewing relevant literature, thus setting the stage for the proposed research.

Focus on a Specific Title:

Before diving into your literature review, it’s crucial to have a clear understanding of your research focus. Discuss your research topic with your advisor to ensure it is sufficiently specific. You’ll also need to determine the number and type of references required to support your citations, whether they be web pages, published books, online journals, or other sources. Decide if your review will include definitions, historical context, or both, to further narrow your scope.

Review Similar Works:

Examining existing literature related to your topic is essential for refining your title and organizing your literature review. This process can also provide inspiration for structuring your final draft. Your bibliography serves as a useful indicator of the breadth of research you’ve conducted, and can help you gauge how well you’ve covered the topic.

Narrow Down Your Topic:

Given the vast amount of literature available on various subjects, it’s important to narrow your focus to a specific area of interest. This approach will help you filter the sources you plan to use, making your task more manageable. Remember, your research guide does not expect you to review 100% of the literature on your topic. Consult your professor to gain further insights and ask specific questions to ensure your literature search is thorough and well-directed.

Use Recent Sources:

In certain fields, particularly those that are rapidly evolving, it’s important to use the most current sources. For example, in medical research, new developments occur frequently, and information from even two years ago may be outdated. Conversely, in the humanities, you may need to explore historical perspectives and demonstrate how concepts have evolved over time. Reviewing bibliographies from other works can provide valuable insights into the scope of your research and suggest new or existing topics of interest to scholars in your field.

Tactics for Writing a Better Literature Review (LR)

Focus Your LR on a Theme:

To create a structured and coherent literature review, it’s important to select a central theme. Rather than organizing your review around individual sources, center it on key ideas and concepts related to your research topic. As you connect these various sources in your LR, consider identifying any gaps in the existing research, noting whether they suggest single or multiple solutions to the problem. 

Additionally, look for patterns or trends within the literature you’ve collected. These considerations will help you develop a more focused and insightful review as you explore a wide range of material.

Communicate Clearly to Your Audience:

Unlike other sections of an academic paper, a literature review does not contain a central argument or thesis statement. Instead, your goal is to guide your readers through the key themes and findings in the literature. Establish clear learning outcomes for your audience and use these as a guiding framework for organizing your review.

Organize Your Work Effectively:

Clarity and organization are crucial when writing a literature review. Present your findings in a clear and direct manner, ensuring that your readers can easily follow the structure of your review. Divide your LR into well-defined topics and sub-topics, and consider both local and global trends related to your research area. This systematic approach will help your readers grasp the full scope of your review.

Categorize Your Work:

Like any academic or scientific paper, your literature review should be divided into several key sections: Introduction, Body, and Conclusions. 

Here’s a brief overview of these categories:

• Introduction: Introduces the main theme and structure of your LR, setting the stage for the discussion.

• Body: Analyzes and discusses various sources, organized methodologically, thematically, or chronologically. This is where you explore the key ideas and connections between different studies.

• Conclusions: Summarizes the key findings from your review, provides recommendations, and reflects on what you have learned from the literature. This section should highlight the insights and potential directions for future research.

Methods to Organize Your Literature Review:

Chronological Order:

Organizing your literature review chronologically involves arranging the sources based on their publication dates. In this method, you start with the earliest published materials, even if the subjects are not closely connected. However, this approach may sometimes cause the chronological focus of the review to become less coherent if the sources do not naturally link together.

Publication Order:

When you observe a significant trend or development over time, you can organize your literature review by the order of publication. This method helps to highlight the progression of ideas and the evolution of thought within a particular field.

Trending Topics:

Another way to arrange sources chronologically is to group them by trending topics or themes that emerge over different time periods. For example, if you’re studying the history of tigers, you might organize your sources according to distinct historical periods to reveal how perspectives on the species have changed over time.

Thematic Order:

A thematic organization classifies your literature review based on topics or themes rather than time. While time can still play a role in these thematic reviews, the primary focus is on the subject matter itself. Thematic reviews often include various subsections, which can illustrate the transition of ideas or themes across different time periods. The key difference between a thematic and a chronological organization is which aspect—time or theme—is emphasized more prominently.

Methodological Order:

In a methodological approach, the organization of your literature review centers on the research methods used in the studies you’re reviewing. This approach allows you to highlight the different methodologies applied in the research, how they influenced the results, and how these documents were discussed. Within this method, you might consider the following sections:

• Existing Situation: Provide background information necessary to understand the topic or focus of the literature review.

• Chronology: If your literature review isn’t organized chronologically, you might still include a section that covers the history of the literature or ideas essential for understanding the topic.

• Standards: List the criteria you used to select the literature, such as specifying that you only included peer-reviewed articles and journals.

• Questions: Address whether the literature review has raised further questions or if there’s a need for additional research on the topic.

Each of these organizational methods offers a different lens through which to view the literature, helping you to present your findings in the most effective way for your specific research focus.

Once you’ve established the structure of your LR, you can begin writing. Here are some additional guidelines to help you through the process:

Refer to Sources:

As with any academic research paper, your literature review should refer to a range of sources to support your points. Just like in the provided example, citing multiple sources strengthens your arguments and demonstrates the validity of your research. Use current sources to back up your interpretations and ensure your work is up-to-date.

Be Selective:

Carefully select the most relevant points from each source for your LR. Focus on information that directly relates to your chosen approach, whether it’s methodological, thematic, or chronological. This will keep your review concise and on-topic.

Limit the Use of Quotations:

A literature review is generally concise and focuses on summarizing key points rather than lengthy discussions. While it’s acceptable to include a few quotations to emphasize important points, use them sparingly. If you’re unsure about the use of quotes, consult your university guide or experts at PhD Assistance. Prefer paraphrasing over quoting, especially when you can rephrase an author’s ideas in your own words.

Summarize and Connect Sources:

In each section of your LR, summarize the sources you’ve reviewed and clearly link their relevance to your own work. This can be done by rephrasing and emphasizing the importance of the studies in relation to your research.

Maintain Your Voice:

Your voice and perspective should be the central focus of your literature review. As you integrate the research of others, make sure to weave their findings into your own narrative, starting and ending each discussion in your own words and views. This keeps your review cohesive and reflective of your analysis.

Paraphrase Carefully:

When paraphrasing, ensure that you accurately convey the original author’s ideas in your own words. Be meticulous in citing sources according to your university’s style guide, and familiarize yourself with your institution’s plagiarism guidelines to avoid any issues.

Review and Revise Your Work:

After drafting your LR, take the time to revise thoroughly. Your main objective is to present the material clearly and concisely, not to argue a specific point. Revisit your work to ensure it aligns with your assignment and outline. 

Consider reworking the language to be as clear and concise as possible, using terminology familiar to your audience. Eliminate unnecessary jargon or slang, and ensure all sources are correctly cited and formatted according to the standards of your discipline. For additional tips on revising and editing, refer to resources like handouts on revising drafts.

Refer to Books and Style Guides:

Conduct thorough research to identify the most recent publications on your subject. Adhere to your university’s referencing style requirements, and consult the relevant style guides to ensure your citations and formatting are accurate.
