• More about this feature

The Library of Congress Subject Headings (LCSH) is perhaps the most widely adopted subject indexing language in the world, has been translated into many languages, and is used around the world by libraries large and small. LCSH has been actively maintained since 1898 to catalog materials held at the Library of Congress. Proposals for additions and changes are reviewed regularly at staff meetings in the Policy and Standards Division (PSD) and an approved list is published.
