rteeter writes “If you’re not a cataloger (and maybe even if you are), you might not have heard of SACO. Even if you knew that SACO is a cooperative system for proposing new Library of Congress Subject Headings, you’d probably think Web Resources for SACO Proposals would be really dull. But consider this: catalogers proposing new subject headings have to have be sure of their terms. They call it authority work; you might call it reference work.
“So Web Resources for SACO Proposals turns out to be a great place to find all kinds of online topical dictionaries, encyclopedias, and gazetteers.”
Authority Resources
Another great list for the reference folks is Authority Tools for Audiovisual and Music Catalogers: An Annotated List of Useful Resources available on the OLAC site. If you are a cataloger, you should know this group and be a member.
