In this context, the "literature" refers published scholarly work in a field.
Literature includes journal articles, conference proceedings, technical reports, and books.
The literature review must be defined by a guiding concept (eg.
your research objective, the problem or issue you are discussing, or your argumentative thesis).
A poorly written question that is too broad will generate questionable hypotheses, and if your supervisor fails to catch it in time, even more questionable results.
Developing the right question requires a rock solid literature review that establishes your expertise as having been so immersed in the topic that you can rightfully vouch for the need for this research question to be asked.There are some simple rules that can be applied: The quality of your review will sink or swim on the efficacy with which you select your search keywords.Too many and you’ll be buried under results for months.Most researchers struggling to survive in the middle of a literature review tend to worry more about the currency of their data more than the quantity of it.They become paranoid at the prospect of missing the latest paper or opinion piece that an examiner will spring on them at their oral defenses and destroy their academic careers in one fell swoop. The introduction should define the topic and set the context for the literature review. Which areas have been identified as needing further research? The format is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.A literature review can also be a short introductory section of a research article, report or policy paper that focuses on recent research.In the anatomy of a scholarly research article example, the literature review is a part of the introduction.This landscape informs the reader that the author has indeed assimilated all (or the vast majority of) previous, significant works in the field into her or his research."In writing the literature review, the purpose is to convey to the reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are.
