The Alpha Gamma Sigma Sorority existed on the UW-RF campus from 1979 to 1989, and later it then became Lambda Delta Phi. The collection consists of activity files, constitutions and bylaws, correspondence, minutes, a pledge book, rush information, photographs, and scrapbooks that detail different activities of the sorority.

This collection is comprised of records relating to Greek societies on the River Falls campus. This collection mostly contains records of Fraternities and Sororities, at local and national levels. Also included are some academic and honor societies. Most of the Greek organizations were focused on civic involvement, leadership, and life-long friendships, others also focused on specific subject areas such as Agriculture. The records in this series include but are not limited to, constitutions and by-laws, meeting minutes, events and activities, member lists, and correspondence.
