After choosing a topic, you will need to locate introductory sources that give basic background information about the subject. Finding background information at the beginning of your research is especially important if you are unfamiliar with the subject area, or not sure from what angle to approach your topic. Some of the information that a background search can provide includes:
An encyclopedia is a great starting point for researching a topic. In addition to providing a succinct overview of your topic, it will introduce key concepts, keywords, and subject terms that will be helpful as you begin your research.
Subject dictionaries can help with defining and understanding terminology common to the topic.
Handbooks, sourcebooks, and manuals are similar to subject encyclopedias or dictionaries in that they provide background information, facts, and figures about a field or industry.
Wikipedia can be an excellent starting point for collecting background research on your topic. Most instructors will tell you not to cite Wikipedia in your research paper (and rightly so) because pages can be written by anyone and can be subject to errors, bias, vandalism, etc. But even though you can't use Wikipedia as a citable source in your paper, it is still an excellent source for background information. For a better place to start with information that you can cite, try searching Credo Reference.
Tip: Scroll to the bottom of a Wikipedia entry to find a list of References or Notes leading to published sources of information on your topic.
