For those of you who are interested in the latest news from the Joint Steering Committee, their listing of Working Documents is a good place to get details on RDA.
All documents are in PDF. So far, I haven’t had any trouble opening the documents. The reading is a little slow going because of all of the details. However, it is a great insight into the process of RDA. It also is a good opportunity to learn more about the differences of how RDA will treat works, expressions, manifestations, and items.
Hopefully, this site will be regularly updated.
