This bibliography was compiled as part of the United States Agricultural Information Network's National Preservation Program, a National-Endowment-for-the-Humanities-funded effort to identify and preserve state and local literature relating to agriculture and rural life in America between 1820 and 1945. It is being made available for research use as a searchable database.

Included are references to books, pamphlets, serial publications, and theses and dissertations published by state and local entities prior to 1946. Federal publications, legislative documents, compilations of laws, maps, county histories, and manuscripts and archival materials have been excluded.

Thanks to NEH funding, a number of the most significant publications have been microfilmed for preservation; additional funding is needed to preserve a greater number of these titles that serve to document the nation's rich agricultural heritage.
