The literature review provides a comprehensive review for your research area and is necessary to identify works that have been published and to identify gaps in the literature.
It enables you to:
- investigate previous research, find out what’s been done before
- consider theoretical frameworks
- identify ‘gaps’ in existing knowledge to find out if your study is worth doing
- identify seminal works
- determine/clarify/justify your research question/problem
- select the most appropriate methodology and research techniques.
A literature review sets the context for your research and provides the framework for interpreting the results of your research.
