So you run the risk of reproducing something that is copyrighted by someone else, butthe government has a license to reproduce.
The goverment is also able to hold a copyright that has been assigned to it by the original author. This can complecate things quite a bit.
But, if you make an honest (and well documented) attempt to find out if it is covered by a copyright, and you have every reason to believe that it a produced by the government, you are on reasonably safe ground.
