"The always-useful beSpacific blog has a posting on a new FAQ on copyright produced by CENDI, the interagency working group of senior Scientific and Technical Information managers from 12 U.S. federal agencies.

The FAQ is focused on issues relating to copyright in a government setting, and it is excellent. It includes discussion of when government works are copyrighted, what happens when government works are included in other publications, and the copyright status of work produced by Federal contracts and grants. It also has a very useful copyright glossary, and links to many of the copyright notice and permission pages from different federal agencies. And it doesn't avoid taking opinions. Highly recommended."
