Library of Congress Subject Headings (LCSH) is a widely used controlled vocabulary by libraries around the world, but like any controlled vocabulary, it comes with limitations. Come learn about other controlled vocabularies to consider using in your library catalog to help your patrons find the resources they're looking for. Controlled vocabularies to be covered include FAST (Faceted Application of Subject Terminology), AAT (Art and Architecture Thesaurus), and LCTGM (Library of Congress Thesaurus for Graphic Materials).
