The US Copyright Office now has RSS feeds for The Copyright Office Homepage, Copyright NewsNet (presumably duplicating the free e-mail version), Copyright Office Federal Register entries, and copyright legislation. Presuming that these feeds get kept up to date, together the constitute an excellent resource for those trying to keep up with developments in US copyright law.

It's sort of ironic that the Copyright Office has done so much better a job with computing resources than has the Patent and Trademark Office. But that's for another time.
