US federal government
Title 17 USC §105, Subject matter of copyright: United States Government works, provides that "Copyright protection is not available for any work of the United States Government," defined in Title 17 USC §101, as "a work prepared by an officer or employee of the United States Government as part of that person's official duties." Therefore, only those works solely authored by US Federal Government employees are not protected by copyright in the United States.
Works produced by contractors and grantees for the federal government are generally protected by copyright. In such cases, the Government is granted a nonexclusive, irrevocable, worldwide, royalty-free license in the work to reproduce, prepare derivative works, distribute copies to the public, and perform publicly and display publicly, and to allow others to do so, for US Government purposes. The Government's license does not place these works in the public domain. Additionally, a copyrighted work for which the copyright has been transferred to the Government by assignment or bequest is not in the public domain.
Look for copyright and permissions notices on US Federal Government publications and websites. However be cautioned that government agencies often advise that in the absence of a copyright notice, users may assume their information is not copyrighted. This contradicts the copyright law as amended in 1989, when the United States joined the Berne Convention for the purpose of harmonizing domestic copyright law with international copyright standards. While use of a copyright notice and registration was once required as a condition of copyright protection in the United States, it is now optional, and a work is not necessarily in the public domain simply because it does not have a copyright notice.
