“The Terminologies Service provides access to multiple controlled vocabularies to help you create consistent metadata for your library, museum, or archive collections. Now it’s as easy as copy-and-paste into a workform or template once you find a term to use in your description, improving the description of (and access to) your digital and hard copy materials.

“The Service can be integrated with Connexion or used as a standalone tool to copy terms into a variety of metadata editors including the one available in OCLC’s CONTENTdm software.”

The Terminologies Service currently incorporates 11 vocabularies, including AAT, GSAFD, MeSH, TGN, and TGM I and II. I haven’t used it, but it seems like a handy aid for institutions using multiple thesauri. Installation is free with Connexion, and there are several online tutorials for both installation and use.
