What is a Literature Review?
A well-conducted literature review in research demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. It’s essential for answering the question: what is literature review in research and why is it a fundamental step in the academic writing process. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.
What is the Purpose of Literature Review?
A literature review in research serves several important purposes within academic and research contexts. Here are some key objectives and functions of a review of literature in research.[2]
- Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge.
- Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.
- Understanding Theoretical and Conceptual Frameworks: Review of literature in research helps researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research.
- Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered.
- Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research.
- Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature.

Frequently Asked Questions
Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic.
Focus on peer-reviewed journal articles, academic books, and reputable publishers. Evaluate each source for authority, accuracy, currency, and relevance to your research question. Avoid non-scholarly sites unless they offer essential context or primary data.
Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm.[3] A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods.
Citation management tools like Zotero, Mendeley, and EndNote can help you organize references and generate bibliographies. For a more integrated approach, Paperpal’s Cite lets you add papers discovered through AI research directly to your collection with one click. As you write, use Cite Text to select any claim and get relevant citation suggestions from academic literature, or generate citations in your required format (APA, MLA, Chicago) without switching tools, keeping your entire workflow in one place from research to final formatting.
A systematic review follows a strict, transparent protocol defining specific inclusion criteria and systematically searching all relevant studies. A narrative review is more flexible and thematic, offering a broad overview without strict selection rules. Other types, like scoping or meta-analysis, differ in scope and analytical depth scoping maps for broad topics, while meta-analyses use statistical methods to combine study results.
Start by grouping studies with similar themes or findings. Summarize key points, compare differing perspectives, and highlight patterns or contradictions. Use your own words to connect insights across sources, showing how they relate to each other and to your research focus.
Paperpal’s Chat PDF lets you upload up to 10 PDFs simultaneously and ask comparative questions like “What are the common themes across these studies?” or “Where do these researchers disagree?” Paperpal also maintains conversation context, so you can dig deeper into specific findings without re-uploading files.
