Below is graphic that I have used in several presentations and in different workshops. This graphic has been created by Kentucky Virtual Library and is meant to walk students throught the process of doing research from A to Z.
How to Do Research is basically a search map that is centered around web research and also includes a good section about using library catalogs, books, and magazines. I recommend that you print it off and use it with your students in the classroom. Enjoy
