This guide is designed to be a general resource for researchers searching the literature as part of a PhD.
It will cover:
Always refer to the instructions and guidelines your supervisor has provided.
The literature review can be informal, a short introduction to the topic or more substantial, a chapter in a thesis or standalone piece of work. Either way, searching for existing research on a topic and writing this up is an essential part of the research process.
Being organised and having a plan when searching for material is essential. It will add structure, save you time and can also improve the relevancy of the results you find.
There are many reasons to carry out a literature review;
Demonstrate that you are aware of what is already known and understood about a topic.
Demonstrate that you are up to date with current/relevant research.
Identify main theories, arguments, ideas, conclusions and interpretations.
Identify any gaps in the research and potential directions for future research.
Place your research within the wider body of literature.
Provide context and evidence for your research.
To inform readers of your work and of what is happening in a particular research area.
