Faceted Application of Subject Terminology (FAST) is a general use controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by OCLC, Inc., with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as information about a document's form, chronological coverage, or geographical coverage.
Unlike LCSH headings, which are pre-coordinated (multiple terms are linked together by the cataloger in a specific order, e.g. "United States -- History"), FAST headings are post-coordinated (terms are singly assigned, so the user can mix and match, e.g. "United States" and "History").
