Monthly Catalog of U.S. Government Publications (Free)Commonly referred to as the Monthly Catalog or MoCat, this publication lists all of the publications produced by the U.S. Government Printing Office from 1895 to 2004. Initially intended to supplement the Documents Catalog, the Monthly Catalog served as the “comprehensive index” provided for in the Printing Act of 1895 after the Documents Catalog was discontinued in 1947. The Monthly Catalog was discontinued with the December 2004 edition
For publications issued prior to 1976, the online CGP does not provide comprehensive coverage and the Monthly Catalog of U.S. Government Publications should be consulted (see below)
