More than 500,000 records generated since July 1976 are contained in the CGP and it is updated daily. The catalog will grow to include records for publications dating back to the late 1800s, making the CGP the central point for locating new and historical Government publications.
The CGP was originally the online counterpart of the Monthly Catalog of United States Government Publications, which had been printed since the passage of the Printing Act of 1895. The print version of the Monthly Catalog was discontinued with the December 2004 edition.
For publications issued prior to 1976, the printed Monthly Catalog should be consulted. Print editions of the Monthly Catalog and many of the publications indexed in it were distributed through the Federal Depository Library Program. The NNU Library documents collection no longer includes print copies of the Monthly catalog.
