Explore the Quick Search or the recommended Databases (see the box below) to choose a topic and read about it, so you can refine it and get instructor's approval.
Create a list of keywords and other information to use when you search. Use different variations of your keywords (synonyms), and try terms that are more specific or more general, to get different results.
Some databases include a "Citation Tool" that helps you cite their sources. If you use it, be careful: remember to not COPY+PASTE, but instead COPY+PASTE+CORRECT.
