Most literature reviews by students present the highlights of a research area and are not truly exhaustive. There is no strict rule, but a short literature review generally requires about 7-12 research articles and is about 10-15 pages long.

There are three main steps:

(1) select a research topic,

(2) collect and read the relevant articles, and

(3) write the review article. This straightforward-sounding process in fact requires quite a bit of work. Suitable topics must be selected with care and discrimination. Finding the right articles can be a challenge. Finally, once you have selected your articles, you must read them and understand their implications before you can begin to write.
