Library of Congress Subject Headings (LCSH)

LCSH was originally developed to provide a controlled vocabulary for subject indexing the Library of Congress (LC) collection. It is now widely used by other libraries and indexing agencies and in online bibliographic databases.

Subject headings are established as they are needed to catalogue materials being added to the LC collection. Terms in current use are selected in establishing new headings. A single term is selected and synonymous and variant terms provide 'see' references to the preferred term.

Changes are made to maintain the currency and viability of the terms, although decisions on changes also take into account the need for stability of terms.
