The majority of the material contained in this series spans the years 1947-1981, the years Glen Lockery directed the choir, although there are a few programs from earlier concerts. The material is arranged by year, and the file cards list the material found in each folder. Below is a general description of the types of material found in this series.

The items include programs for the Christmas and spring concerts, and occasionally for other concerts given by the choir, itineraries for the annual spring tour, lists of Vandaleer members, correspondence, much of it from appreciative listeners, newspaper clippings, audition evaluations, an internal music department memos.

In 1971 the Vandaleers spent three weeks in Europe and the folders for that year contain correspondence related to the planning and fundraising, maps, itineraries, programs, posters, and press releases relating to that trip.

January 1975 found the Vandaleers in Latin America, and among the more interesting items in the folders for that trip is a scrapbook kept by Audrey Aaron of the University of Idaho foreign language department which contains newspaper articles on the Vandaleers and their concerts.

Three miscellaneous folders contain material relating to Vandaleer recordings, photocopies of material from Wm. E. Jorgensen who was a member of the group from 1936-1938, and music, including Alma Mater (Idaho), Oh, Let us Sing of Idaho, Here We Have Idaho, and Go, Vandals, Go.
