You may be surprised what you can find here!
At the earliest stages, you may want to consult encyclopedias, dictionaries, handbooks, or other reference sources which offer brief introductions to or summaries of a topic. Wikipedia is often a good place to start, but you can also use Credo Reference, a large collection of published academic sources, or select from a list of subject specific online reference sources.
If you want to go straight to finding books, articles, video and sound recordings, images, etc., you can use OneSearch, a Google-like search engine that searches most (but not quite all) of Wesleyan's library resources (both online and offline materials). Or select a subject specific index or database which can offer deeper and more specific coverage of a particular topic. Whatever search tool you use, make sure you use effective searching techniques to get the best results for your efforts.
Also remember you can ask a librarian at any point during your research for more specific and detailed assistance.
