Federal Government Publications
Catalog of U.S. Government Publications (CGP) by GPO, for materials published from 1976 to the present. The database contains information about publications of all types issued by the federal agencies, including monographs, periodicals, bulletins, reports, congressional documents, etc. It also provides links to full-text of many publications.
Monthly Catalog of United States Government Publications (MOCAT) can be used to find bibligraphic records for federal documents published by the federal government agencies from 1895 to 1975. This print version was discontinued in 2004, but is still available through Federal Depository Libraries.
A paid version of the Monthly Catalog is available from ProQuest.
U.S. State Publications
Like the Federal Depository Library Program for Federal documents, state depository library systems exist for documents issued by states. State depository systems are often part of the programs at state libraries. Documents can be found online or listed in the catalogs of individual depository libraries.
Worldcat from OCLC is one of the largest listings of library holdings around the world, with an emphasis on North America. Federal, state, and local documents cataloged by all types of libraries can be found here.
