What is an RRL?
An RRL (Review of Related Literature) is a summary of past research on a topic. It helps researchers understand what has already been studied and find gaps for new research.
A Review of Related Literature (RRL) is a critical analysis of existing studies that provides background, identifies research gaps, and supports the theoretical framework of a new study.
The Review of Related Literature (RRL) serves as an analytical synthesis of prior research, establishing a conceptual foundation, identifying methodological gaps, and justifying the significance of a study within an academic discourse.
What is an RRL?
A Review of Related Literature (RRL) is a critical section in research papers, theses, and dissertations. It involves summarizing, analyzing, and synthesizing previous studies relevant to your research topic. The primary purpose of an RRL is to:
- Understand the existing knowledge in your field.
- Identify gaps or areas that need further research.
- Establish a strong foundation for new research questions, hypotheses, and methodologies.
An effective RRL does more than just summarize past studies. It synthesizes different viewpoints and findings to guide future research.
Role in Research Papers, Theses, and Dissertations
The RRL is a fundamental part of academic writing. It serves several key purposes:
- Provides Context: It situates your study within the broader academic conversation.
- Identifies Gaps: It highlights areas where more research is needed.
- Supports Research Design: It helps you shape your research questions and methodology.
- Prevents Redundancy: It ensures that your research brings something new and original.
- Builds a Theoretical Framework: It connects your study to existing theories and models.
RRL vs. Book Review
Although both the RRL and a book review involve analyzing existing work, they serve different purposes:
- RRL: Focuses on synthesizing research across multiple studies to guide future research.
- Book Review: Focuses on critiquing a specific book or author.
| Feature | Review of Related Literature (RRL) | Book Review |
| Purpose | Summarizes and synthesizes research to inform new studies | Critiques a specific book |
| Scope | Covers multiple studies, articles, and scholarly sources | Focuses on one book or author |
| Approach | Objective and evidence-driven | Subjective and opinion-based |
| Use in Research | Essential for guiding research design | Literary analysis for critique |
| Tone | Neutral and fact-based | Often opinion-based |
