The RDA Toolkit blog has an interesting post on RDA news coming out of the American Library Association Annual Conference. Here's a snippet:
It was a busy day at the ALA Conference for RDA and RDA Toolkit. The U.S. Test Committee met with vendors, testers, and the public, and summarized the results of the test and the reasoning behind their recent decision. The committee stated that the "rewrite" of RDA will actually be more of a rewording, intended to simplify and clarify some of the instructions. Cataloging practice will not be affected by the rewording. We also learned that the Library of Congress will begin partial RDA cataloging in November. They will catalog across all subject areas and expect RDA records to represent about 5% of the library's cataloging output. The National Library of Medicine and the National Agricultural Library will not catalog in RDA until full implementation begins.
