A step better than general Google searching or Wikipedia, try...
The library has a variety of online reference works that may contain relevant articles, including...
Also try general searches in the library catalog. You can search by keyword, subject heading, author name, etc. Don't forget that you can limit to online sources or by library location or availability. Very broad searches will yield very broad results, most of which will be irrelevant. Try to be specific, and once you find something relevant, it may lead you to additional relevant items (by the same author, in the same book series, with the same specific subject heading).
