The South Dakota Farmers Union Records provide a comprehensive account of the organization’s history, advocacy, and role in shaping agricultural policy from the early 20th century to the early 2000s. The collection documents the Union’s efforts to support family farmers, promote cooperative enterprises, and influence state and national agricultural legislation. Materials include organizational records, correspondence, meeting minutes, financial statements, educational materials, photographs, audiovisual recordings, and publications.

A significant portion of the collection pertains to the Union’s legislative and political engagement, featuring records from state and national conventions, speeches, campaign materials, and lobbying efforts. These materials illustrate the Union’s role in advocating agricultural policy reforms, rural economic development, and cooperative business models. Key figures such as Ben Radcliffe, George McGovern, Hubert Humphrey, and Eleanor Roosevelt are represented in convention proceedings, recorded speeches, and radio broadcasts. The 1972 Supreme Court case on public school funding through property tax is also documented through clippings, correspondence, and legal evidence.

The audiovisual materials consist of 13 audiocassettes, 156 open reel tapes, 6 wire recordings, and 34 16mm motion picture films, spanning from 1948 to 1992. These recordings capture state and national conventions, radio programs, speeches, and advertisements, along with footage of state camp activities, tours, picnics, and parades. Many of the materials promote legislative initiatives and endorse political candidates. In 2018, the South Dakota Farmers Union audiovisual collection was digitized with the support of a Recordings at Risk grant from the Council on Library and Information Resources. Due to the fragile state of many recordings, the Archives partnered with George Blood L.P. to ensure high-quality digital preservation in sustainable formats.

The Cooperative Legacy Project, spearheaded by Chuck Groth, communications director for the South Dakota Farmers Union from 1972 to 2008, provides an in-depth oral history of the cooperative movement in South Dakota. This project includes over 110 hours of digital audio interviews with Farmers Union members, cooperative managers, and farm organization leaders. The interviews, recorded in MP3 and WAV formats, are supplemented by documents, scanned photographs, and rough transcriptions, offering insight into the history and impact of the cooperative movement.

The collection also includes publications from the National Farmers Union and various state organizations, as well as South Dakota Farmers Union-produced materials such as convention programs (1938-1983), policy statements (1954-1988), handbooks, and brochures. The photographic collection, comprising over 33,000 photographs and negatives, documents youth programs, conventions, picnics, tours, and key moments in the organization’s history, as well as images published in the South Dakota Union Farmer.

Records from local unions throughout South Dakota provide insight into grassroots organizing efforts, consisting of charter records, attendance logs, minutes, and correspondence, with some materials accompanied by photographs.
