Review of Related Literature (RRL)

What is a Review of Related Literature?

A Review of Related Literature (RRL) is a critical analysis of existing research, studies, and information relevant to your topic. It helps you understand what has already been studied, identify research gaps, and establish a foundation for your work.

Where to Find Credible Sources

When conducting an RRL, it's essential to use reliable and scholarly sources. Here are some recommended platforms:

✔ Google Scholar (scholar.google.com) – A free search engine for academic papers, theses, and journals.
✔ ScienceDirect (www.sciencedirect.com) – A database for scientific and technical research papers.
✔ IEEE Xplore (ieeexplore.ieee.org) – A reliable source for IT, engineering, and technology-related studies.
✔ PubMed (pubmed.ncbi.nlm.nih.gov) – Best for medical, healthcare, and bioinformatics research.
✔ ACM Digital Library (dl.acm.org) – A great resource for computing and software development research.
✔ Industry Reports & White Papers – Available from companies like Gartner, McKinsey, and IBM. These provide insights into business and technology trends.
✔ Government and Institutional Websites – Official sources such as the World Bank, UNESCO, or local business bureaus often have high-quality research publications.

How to Identify and Evaluate Sources

When selecting sources for your RRL, consider the following factors:

✔ Relevance – Does the source directly relate to your research topic?
✔ Credibility – Is the author reputable? Is the source from a peer-reviewed journal or a well-known institution?
✔ Timeliness – Is the research recent? (Preferably within the last 5-10 years for most fields, unless historical analysis is needed.)
✔ Objectivity – Does the source provide balanced information, or is it biased?
✔ Methodology – Does the study use reliable and valid research methods?

How to Structure Your RRL

A well-structured RRL follows these steps:

Introduction – Briefly introduce your research topic and why reviewing literature is important.
Body – Categorize sources based on themes or concepts. Compare findings, highlight similarities, and point out gaps.
Conclusion – Summarize key insights and explain how your research will contribute to the field.

Example: Data-Driven Decisions in Businesses

Research Question: How do businesses use data analytics to improve decision-making?

Journal Articles – Studies from Google Scholar show how predictive analytics helps companies forecast sales.
Industry Reports – McKinsey’s research on how big data improves operational efficiency.
Case Studies – Amazon’s use of AI for personalized recommendations.
Tech Blogs – Analysis of real-world applications from reputable sites like TechCrunch and Harvard Business Review.

By critically reviewing these sources, researchers can form a solid foundation for their study and identify innovative approaches to problem-solving.
