What are Subject Terms?

A subject term is a standardized word or phrase that describes a main idea in the article.

When an article is added to a database, the database will assign subject terms to it from the database's list of subjects. Most articles will have from 3 to 12 subject terms.

Each database has its own list of subject terms. They often use technical jargon and odd punctuation, so you won't be able to come up with the subject terms on your own. You will have to identify the subject terms in the database, and then use them in a search.

If you want to see all the subject terms used in a particular database, you can search the Subject Index.

Where do you find Subject Terms?

Most databases list subjects under each result.

In other databases you will need to click the article title. Then look for the subjects to the right of the abstract.
