The Catalog of U.S. Government Publications (CGP) is the finding tool for electronic and print publications from the legislative, executive, and judicial branches of the U.S. government. These publications make up the National Bibliography of U.S. Government Publications. The CGP contains descriptive records for historical and current publications and provides direct links to those that are available online. The CGP is the online counterpart of the Monthly Catalog of United States Government Publications, which dates from the passage of the Printing Act of 1895. At present the Monthly Catalog should be consulted for pre-1976 indexing. The Monthly Catalog and many of the publications indexed in it were distributed through the Federal Depository Library Program.
