Introduction to literature reviews
Introduction - Literature Reviews - GSU Library Research Guides at Georgia State University
Literature reviews can be stand-alone documents, or they can form part of a research proposal or project. A stand-alone literature review aims to summarise and evaluate the current knowledge of a specific topic, whereas a literature review that forms part of a research proposal or project also describes the gaps in the current knowledge that the project aims to address. This module is intended as an introductory guide to writing stand-alone literature reviews. A graduate literature review module is also available in the graduate research and writing section of the Research and Learning Online site. The graduate literature review module is particularly useful if you are writing a literature review that forms part of a research project, including an Honours, Master by Research or PhD project. The purpose of a stand-alone literature review is to provide a summary, synthesis and critical evaluation of the literature relevant to your specific research question or aim.
How to write a literature review
A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study. Fink, Arlene.
In essence, a literature review identifies, evaluates and synthesises the relevant literature within a particular field of research. It illuminates how knowledge has evolved within the field, highlighting what has already been done, what is generally accepted, what is emerging and what is the current state of thinking on the topic. In addition, within research-based texts such as a Doctoral thesis, a literature review identifies a research gap i. However, your literature review does not need to be inclusive of every article and book that has been written on your topic because that will be too broad. Rather, it should include the key sources related to the main debates, trends and gaps in your research area.
