Besides enlarging your knowledge about the topic, writing a literature review lets you gain and demonstrate skills in two areas
- information seeking: the ability to scan the literature efficiently, using manual or computerized methods, to identify a set of useful articles and books
- critical appraisal: the ability to apply principles of analysis to identify unbiased and valid studies.
A literature review must do these things
- be organized around and related directly to the thesis or research question you are developing
- synthesize results into a summary of what is and is not known
- identify areas of controversy in the literature
- formulate questions that need further research
