This means that almost everything on U.S. government websites is not subject to copyright, but there are important exceptions. For example, on the old whitehouse.gov website they had some nice biographies of all the Presidents.... except they didn't produce them, they were using them by permission from a copyright book. We would not be able to use those. In general, if the publication is a publication *of the government*, then it's legal to use it, unless it says otherwise. --Jimbo
