Library Research Guide

Use subject terms

Many databases include subject terms or descriptors for each item they describe. For example:







If we know what subject terms a database uses to express a particular concept, we can use those terms to create precise searches.



So, how do you discover what subject terms the database uses?  One way is to do a broad keyword search and examine the records (description of the item) for the results you like best. If you notice that a particular subject term appears on several of the articles you like, use that term in a new search. Many databases provide another way to find subject terms: the thesaurus. A database’s thesaurus is a listing of the terms it uses. Many thesauri provide a brief description of what the term is used for, broader terms, narrower terms, and related terms. Each database has a different thesaurus.
