Publications Incorporating United States Government WorksWorks by the U. S. Government are not eligible for U. S. copyright protection. For works published on and after March 1, 1989, the previous notice requirement for works consisting primarily of one or more U. S. Government works has been eliminated. However, use of a notice on such a work will defeat a claim of innocent infringement as previously described provided the copyright notice also includes a statement that identifies either those portions of the work in which copyright is claimed or those portions that constitute U. S. Government material.
Example: copyright © 2000 Jane Brown.
Copyright claimed in Chapters 7-10, exclusive of U. S. Government maps
Copies of works published before March 1, 1989, that consist primarily of one or more works of the U. S. Government should have a notice and the identifying statement.
Unpublished WorksThe author or copyright owner may wish to place a copyright notice on any unpublished copies or phonorecords that leave his or her control.
Example: Unpublished work © 1999 Jane Doe
