A good literature review
Literature review is like searching and arranging the scattered pieces of a jigsaw puzzle to create a picture and then describing the picture in segments (including both the clear and the fuzzy parts). It is essential that you succinctly highlight the fuzzy or the missing piece to build that up as your study hypothesis and create an alternate piece through the rest of your research document.
This was just some portion of what this resource would offer you. Read out more through the attached pdf, which tells key elements of literature review, questions that it must provide answers to, brief pointers on how to read critically while preparing a lit-review section and the process of drafting one.
