[This is an extract of my class room notes,....] [As told by Prof.Dr.Amudavalli Ph.D.]

Literature survey is something when you look at a literature[publications]in a surface level or a bird's eye view, or an ariel view. It includes the survey of place people and publications is context of Research. It is a phase where the researcher tries to know of what are all the literatures related to his/her area of interest. And the relevant literatures are short-listed. And in general, a literature survey guides or helps the researcher to define/find out/identify a problem.
Whereas a literature review is going into the depth of the literatures surveyed. It is a process of re-examining, evaluating or assessing the short-listed literatures [literature survey phase]. Review of literatures gives a clarity & better understanding of the research/project, etc.

Thank You.
