Research 101: Subject Terms

Information on the research process.

Subject Terms or Descriptors

If you are not finding relevant resources using keyword searches, try using subject terms, also know as descriptors. These are terms assigned to resources by catalogers using a standardized vocabulary. They are conducive to more precise searching. You will often find subject terms or descriptors in a resource's full record. Some databases also have a thesaurus where you can look up subject terms.
