Learn the difference between using keywords vs. subject headings to build your search.
Keyword searches look for your terms anywhere in the record -- e.g., in the title, abstract, subject heading, or other notes. Keyword searches may be less precise or relevant than searches using subject terms.
Subject headings (sometimes known as descriptors) describe the content of each item in a database. Use these headings to find relevant items on the same topic. Searching by subject headings is often the most precise way to search databases.
Tips on how to locate subject headings
Start with a keyword search.
Browse your results until you find 2 or 3 relevant titles.
Look at the "subject" or "descriptor" assigned to the titles and re-do your search using the terms listed.
Look to see if the database has an online thesaurus to browse for subjects that match your topic. (Check the Help screens)
