I don't mean to sound alarmist or anything, but Library of Congress must actually be letting their cataloging department fall by the wayside. I tried to call the CDS to order a subscription to the Cataloging Bulletin, and was greeted with nothing but transfers to mailboxes that were already full. It was really heartening, let me tell you.
I'm not a crazy cataloger, and I don't mind that much if Library of Congress decides to make changes to it's own library, but in case they didn't notice, LOC is basically the only source that librarians have for creating and maintaining organizational standards. They need to think about that before they decide to throw away their responsibilities towards the entire American library system.
