Finding Reference Sources

Why Reference Sources?

Is your research topic too big to cover in a short paper?  Is your topic so specific that sources will be hard to find?

Before you even begin your research, start the process with reference sources-- in the Library's Reference Section or online in our databases.  Reference books, like subject encyclopedias, can give you a head start and make your research easier in the long run.  Use reference sources to:

  • find a topic
  • narrow your topic
  • find keywords
  • get background information on your topic

Use the menu to the right to find the reference tool that will best help you start the research process.
