A LITERATURE REVIEW is a formal survey of professional literature that is pertinent to your particular question. In this way you will find out exactly what others have learned in relation to your question. This process will also help frame and focus your question and move you closer to the hypothesis or focused question.

Once you have decide on a general research question, you need to read widely in that area. Use the same sources of information that you consulted when you came up with your general question, but now narrow your focus. Look for information that relates to your research question.
