Well, as a cataloging librarian, I can't resist responding to this one. Most thesauri are specific. They are usually produced by a specific group of subject specialists to control terminology in their field. For example, the National Library of Medicine (US) produces a thesauri of medical subject terms, and the National Agricultural Library (US) has one for agriculture and related subjects. You have mentioned the Getty products already, and the AAT. All have the experts structuring the subject terms that apply to their area. The Library of Congress has two specialized thesauri, one for graphic material another for the description of rare books. The most general lists are maintained by those generalists, libraries. Many public libraies use the Sears List of Subject Headings. The Library of Congress publishes lists of subject headings (not a true thesaurus--but a structured vocabulary), the National Library of Canada also publishes subject headings in English and French :-) To my knowledge, the library community is still working on subject thesauri in the field of theology. Yes, there are lists of thesauri, they are usually called bibliographies. Go to a library and ask, typically a bibliography of reference books will include a chapter on thesauri. Just bear in mind the fragmented nature of subject thesauri. One-stop shopping isn't always available. Marianne Cavanaugh Associate Librarian Saint Louis Art Museum
