Audio Cassettes Collection consists of 53 boxes of audio recordings dating from 1914-2008, by various creators and relating to various aspects of Northwestern University life and faculty and alumni careers.

This compilation documents student movements at Northwestern University between 1978 and 1986 which, in protest of apartheid in South Africa, called for Northwestern to divest from companies with economic ties to South Africa. The compliation consists of clippings, reports, flyers, and other documents from a variety of sources.

Acquired over decades from a variety of sources, principally Northwestern University’s public relations units and as separations from the manuscript collections of Northwestern faculty and administrators, the photographic negatives in nitrate format date to the period of that format’s popularity, circa 1890 to circa 1950.
