  • What findings or conclusions does the research present?
  • How does this work add to, support, or challenge what’s already known in your field?
  • Consider the strengths and weaknesses of the research.
  • How current is the information in the publication?

It’s also important to guarantee the reliability of your sources. Prioritize reading key studies and foundational theories relevant to your topic. This step is not only about collecting data but also about building a solid basis for your own research.

Recording and citing your sources

As you delve into the research for your literature review, it’s not just about reading and understanding the material, but also about organizing and documenting your findings effectively. This process is key to putting together a clear and well-supported literature review. Let’s look at some key steps to guarantee you effectively record and cite your sources.

  • Start writing while reading. Begin taking notes as you read, which will be instrumental for your literature review.
  • Track your sources. Consistently record your sources with proper citations to prevent plagiarism.
  • Make a detailed bibliography. For each source, write down all the reference information, a brief summary, and your comments. This helps keep your research organized and clear.
  • Use a plagiarism checker. Regularly check your literature review with a student-friendly plagiarism detection tool, like our platform, to support academic integrity.

Following these steps not only simplifies the process of collecting your literature review but also safeguards the credibility of your work. An organized approach to documenting sources and a watchful check against plagiarism are essential practices in academic writing. They guarantee that your literature review is both broad and ethically sound, reflecting your diligence and attention to detail.

Discovering themes, discussions, and gaps

As you move towards structuring your literature review, it’s important to learn how the sources you’ve read interconnect and relate to one another. Through your readings and the notes you’ve collected, start to identify:

  • Appearing trends. Follow if certain theories or methods have earned or lost popularity over time.
  • Regular themes. Note down any regular questions or ideas that appear throughout your sources.
  • Areas of discussion. Identify where there is disagreement or conflict between the sources.
  • Key publications. Look out for significant studies or theories that have notably influenced the field.
  • Uncovered gaps. Pay attention to what is not discussed in the literature and any potential weaknesses in the existing research.

Additionally, consider:

  • Research evolution. How has the understanding of your topic developed?
  • Author credibility. Consider the credibility and background of the authors contributing to your topic.

This analysis will not only form your literature review but also show where your research fits into the existing body of knowledge.

For example, in your review of the literature on remote work and its impact on employee productivity and well-being, you keep that:

  • A significant part of the research highlights productivity metrics and performance outcomes.
  • There’s growing attention to the psychological effects of remote work on employees.
  • However, there appears to be limited in-depth analysis of the long-term well-being and job satisfaction in remote work environments — this presents an opportunity for further exploration in your research.

Structuring your literature review

The way you organize your literature review is crucial and can vary depending on its length and depth. Consider combining different organizational strategies to create a structure that best supports your analysis.


This method tracks the evolution of your topic over time. Rather than just listing sources, delve into the changes and key moments that have influenced the topic’s development. Interpret and explain why these changes have happened.

For example, In examining the impact of remote work on employee productivity and well-being, consider a chronological approach:

  • Begin with early research focusing on the feasibility and initial adoption of remote work.
  • Examine studies that explore the initial effects of remote work on employee productivity and challenges.
  • Look at the latest research delving into the long-term impact of remote work on employee well-being and productivity, especially considering technological advancements.
  • Consider the significant growth in remote work dynamics and its understanding due to global events like the COVID-19 pandemic.


When your literature review includes sources from different areas or fields with various research methods, it’s useful to compare and contrast what they find. This way, you get a well-rounded view of your topic.

For example:

  • Analyze the differences and similarities in findings from qualitative research compared to quantitative studies.
  • Explore how empirical data contrasts with theoretical research in shaping understanding of the topic.
  • Categorize your sources based on their methodological approach, such as sociological, historical, or technological perspectives.

If your review focuses on how remote work affects employee productivity and well-being, you might contrast survey data (quantitative) with personal employee experiences (qualitative). This could reveal how statistical trends in productivity align with employees’ personal well-being. Comparing these different methodological insights can highlight effective remote work practices and pinpoint areas needing further research.


When your research reveals common themes, organizing your literature review into thematic subsections is a reasonable approach. This approach allows you to explore each aspect of the topic in depth.

For example, in a review focused on the effects of remote work on employee productivity and well-being, you could split your literature into themes like:

  • How digital tools and platforms help or obstruct remote work productivity.
  • Examining the impact of remote work on employees’ personal lives and overall well-being.
  • The influence of leadership and management styles on remote worker productivity.
  • How remote working situations affect employee motivation and engagement levels.
  • The psychological effects of long-term remote work on employees.

By breaking down the literature into these thematic categories, you can provide a complete analysis of how remote work impacts various dimensions of employee life and performance.


In a literature review, building a theoretical framework is a fundamental step. This involves a deep dive into various theories, models, and key concepts that are relevant to your topic.

For example, when exploring the topic of remote work and its effects on employee productivity and well-being, you might consider:

  • Examining organizational behavior theories to understand the structural changes and adaptations in remote working environments.
  • Discussing psychological theories to analyze the impact of remote work on employee mental health and job satisfaction.
  • Looking into communication theories to evaluate how virtual communication affects team dynamics and productivity.

Through this approach, you can set a theoretical basis for your research, combining different concepts to form a wide understanding of how remote work influences both organizational structures and employee well-being.


Starting your literature review

A literature review, much like any scholarly text, should be written with an introduction, body, and conclusion. The content within each section should unite with the goals and objectives of your review.


For your literature review’s introduction, ensure to:

  • Set clear focus and purpose. Clearly describe the main focus and objectives of your literature review.
  • Summarize your research question. If part of a larger work, briefly outline your central research question.
  • Overview of the research landscape. Provide a brief summary of the existing research in your field.
  • Highlight relevance and gaps. Emphasize why your topic is relevant at present and point out any significant gaps that your research seeks to fill.

This structured approach ensures that the introduction to your literature review effectively sets the stage for the detailed analysis that follows.


The body of your literature review should be organized effectively, especially if it’s lengthy. Consider splitting it into clear subsections based on themes, historical periods, or different research methodologies used in the sources. Subheadings are a great way to give structure to these sections.

In constructing the body of your review, keep in mind the following strategies:

  • Summarization and synthesis. Offer a concise overview of each source’s main points and twist them together to form a suitable narrative.
  • Analysis and personal insight. Go beyond simply repeating what others have said. Invest your analysis and insights, interpreting the significance of the findings about the overall field of study.
  • Critical assessment. Talk about the strengths and weaknesses of your sources. This fair approach is important for a complete and honest review.
  • Readable structure. Guarantee your paragraphs are well-structured and cohesive. Use transition words and topic sentences effectively to create a seamless flow of ideas.
  • Linking theory and practice. Where appropriate, connect theoretical concepts with practical examples or case studies from your sources.
  • Highlighting methodological differences. If relevant, discuss how different methodologies have impacted the conclusions of your sources.

Remember, the body of your literature review is where you lay out the groundwork of your research, so it’s important to be detailed, analytical, and methodical in your approach.


In your conclusion, bring together the important points from your literature review. Make sure to:

  • Highlight key takeaways. Sum up the main points you discovered from the literature and highlight why they’re important.
  • Address research gaps. Show how your review fills in missing pieces in the existing research and adds new insights.
  • Link to your research. Explain how your findings build upon or use current theories and methods, forming a base for your own research.

After finishing your draft, a careful review is essential. Go over your work to ensure it’s clear and well-organized. If proofreading isn’t your strength, getting help from professional proofreading services can be a good idea to make sure your literature review is polished and error-free.
