Library of Congress Subject Headings are assigned to every title (with a few exceptions) in our catalog, usually more than one subject heading is assigned to each title. Only one determines its call number, but all are helpful tools for navigating the catalog and confirming what the most effective keywords for your topic are. Searching using words from the Subject Heading's controlled vocabulary is a great practice to get in the habit of doing.
