When beginning research on a new topic, it’s often a good idea to start by reading one or several encyclopedia articles on it. This serves two purposes:

  1. Gives you an overview of the topic, plus some of the important terminology associated with it which you can then use when searching in databases, library catalogs, etc.
  2. Often provides a brief bibliography at the ends of the articles, i.e., sources specifically recommended for further research by the author of the article. It’s usually a very simple matter to track these down in ALICE or OhioLINK.
For more about the effective use of encyclopedias, see this page about types of research tools. Many of our Subject and Course Guides will also contain information on and links to encyclopedias on particular areas of research.

We recommend that you try using one or more of the sources below to find background information on a topic:
