This collection documents the activities and presence of a wide range of student organizations at South Dakota State University, representing academic, professional, cultural, religious, political, and recreational interests. Materials span more than a century of student life and showcase the diverse extracurricular landscape of the university.

This is an artificial collection composed of ephemeral and documentary material related to SDSU student organizations. It includes flyers, newsletters, charters, constitutions, programs, brochures, clippings, correspondence, and award certificates. The collection is not comprehensive, and materials have been added informally as discovered. Some items date as far back as the Class of 1891, while others represent 20th and 21st-century groups, such as cultural associations (e.g., Chinese Student Association, Black Student Alliance), professional and academic clubs (e.g., Agronomy and Conservation Club, Sigma Tau Delta), Greek organizations, and recreational or service groups (e.g., Habitat for Humanity, Karate Club). File size and completeness vary greatly across organizations.

This collection offers a snapshot of student engagement at SDSU across generations. It reflects changing student interests, identities, political affiliations, and social movements. Particularly valuable for those studying student activism, campus culture, and organizational development, it captures the evolving role of student leadership and extracurricular involvement in shaping the university's history.
