This collection documents the activities of Beta Omega Tau, a sorority on the Northern Michigan University campus in Marquette, Michigan. Records include correspondence, financial materials, photographs, and meeting minutes. Photographs are of a class reunion in the late 1980s and of a dinner in Lee Hall in the 1950s. The minutes of meetings are the most important component of the collection and include the constitution, pledge riturals, some lists of members, and regular lists of officers. The collection's materials date from 1929 to 1989.
