Subject Searching

Most periodical indexes organize their records using a list of approved subject headings. This allows you to find all the articles about your topic under one term.

How do you find the approved subject headings? Some indexes provide a list of subject headings. This list is called a subject guide or a thesaurus. If you search for a word that is not in the index, it may suggest an approved subject heading you could use.
