Although presented here as a step by step process, the overall sequence of a literature search is not linear. It is more of a circular path in which you find some material, read it, then using the information you found, refine your search terms and go back and search again. That circle may need to be repeated more than once for each database and don't forget that the process must be used in every resource that you try.
The process will take time and you'll find that you can't do it all at once. You don't want to waste time repeating work you've already done, so as you go thru the process, keep track of what databases you've searched and what search strategies you've used in each database.
Three different methods are outlined below: Subject, Author and Citation. Although there will be overlap in the results you get, each method will find unique items that the other two searches couldn't.
Suggestions for keeping up with all the literature you'll be finding ...
