Controlled Authorities/Vocabularies

• LC Linked Data Service (http://id.loc.gov/) - Includes one-stop lookup access to:
  • Library of Congress Subject Headings (LCSH) - Used for subjects/topics/geographic subdivisions.
  • Library of Congress Name Authority Files (LCNAF) - Used for persons, organizations, events, places, and titles.
    • CHF is part of the Name Authority Cooperative (NACO), so can directly contribute to authorized name records.
  • Library of Congress Genre/Form Terms (LCGFT) - Used to describe what a work is (as opposed to LCSH) and its format.
    • For example, "Horror films" could be an LCSH subject for a book on about horror films, but can also be a LCGFT term for movies where "horror" is the genre and "film" is the form.
  • Thesaurus for Graphic Materials (TGM) - Used for visual materials. Includes specialized subject and genre/format terms for photographs, prints, design drawings, ephemera, and etc.

**LC Linked Data Service also contains many other vocabularies, but the above would be the most initially relevant for CHF.

**Less CHF relevant but still useful Getty Vocabularies:

• • Cultural Objects Name Authority (CONA - http://www.getty.edu/research/tools/vocabularies/cona/index.html) - Fairly new vocabulary (introduced 2011) containing title, location, and other descriptive information for cultural works. "In general, CONA does not include records for objects in natural history or scientific collections, although there are exceptions for works of particularly fine craftsmanship that are of the type collected by art museums."
  • Union List of Artist Names (ULAN - http://www.getty.edu/research/tools/vocabularies/ulan/index.html) - Used for artist and architect names, roles, and nationalities.
