I don't think the inclusion of non-NAF headings in Identities is a flaw, it's a benefit to the purpose of Identities not to be held back by the somewhat glacial pace of change in NAF. But you're right, the right tool for the job, I don't know that any of the existing OCLC "free" (or included with other OCLC membership/services) services are the right tool to replace any existing purchased authorities tools or sources. It depends on what you're using them for, of course. I agree that the brochure statement was potentially misleading, but these (Identities, Terminologies, Research Terminologies) are still very interesting and useful services. ________________________________________ From: Code for Libraries [[log in to unmask]] On Behalf Of Ya'aqov Ziso [[log in to unmask]] Sent: Friday, March 19, 2010 2:14 PM To: [log in to unmask] Subject: Re: [CODE4LIB] WorldCat Terminologies Karen, Seems like pulling-teeth was worth it. Thank you for these updates and for making them available for all interested. Essentially, given your 6 months latency compared to http://id.loc.gov) and the inclusion of NAF and non-NAF headings in Identities, both Terminologies and Identities are not yet at a level of databases that libraries can go for, forgoing what they currently need to buy, load, and maintain locally. Your withdrawal of the brochure statement is justified and apology accepted.
