Reference works -- like encyclopedias, handbooks, and dictionaries -- provide great overviews and background information.
In short, reference works are a great way to begin your research.

"Wikipedia? It's a great place to start, and a horrible place to end, at least that's what my professor says."
Wikipedia can be a great place to begin finding information on a topic, trend, or issue. You'll need to find additional sources, but Wikipedia articles may help you learn more about your topic. Use the citation list at the bottom of Wikipedia entry pages to lead you to more sources.
