In many of the library's databases, you will find the list of assigned subject headings (sometimes called descriptors) in the record for the article. See the below image as an example of where you can find the subject headings:
Some databases offer a thesaurus that lists related subject headings. Usually, you can find a link to this list near the top of the page.

AND narrows your search
OR broadens your search
NOT excludes terms
