United States Government Information

Since the 19th century, various finding aids or indexes for U.S. Government information have been compiled by the U.S. Government Printing Office (previous agency name of the U.S. Government Publishing Office), other Federal agencies, or at the direction of Congress. These indexes allowed users to locate publications primarily by title, author, and/or subject.
