Addendum: The reason Federal projects are in public domain is that they are not (cannot be?) copyrighted. This is generally true for internal and commissioned projects. In the grant papers I've seen there is an explicit warning to the effect that the work done cannot be copyrighted. One can't take too seriously the credits on USArmy films of the 'forties. They are generic boilerplate similar to the credits on training manuals. Cal Pryluck <PRYLUCK@TEMPLEVM> Dept of Radio-Television-Film <[log in to unmask]> Temple University Philadelphia, PA 19122
