The Charles E. Krosse Collection contains films produced and/or distributed by a Peoria film production company, C.L. Venard Productions, a company that became known for its educational films dealing with agricultural subject matter. The collection contains both 16mm and 35mm films, a number of which may also be titles that Venard employees collected. Included in the collection are promotional and in-house training films made for Caterpillar, a fundraising film made for the city of Peoria, some soft-core erotic shorts, unrelated animated shorts, silent film comedies, and unidentified home movies.

The Chuck Olin Collection is comprised of films made by Chuck Olin from his work at two Chicago area film production companies from the mid-60s to the late 1990s: first with the Film Group/Mike Gray Associates and after 1974 with his own Chuck Olin Associates. Included are political documentaries made by the Film Group on the 1968 Democratic National Convention; television commercials for a variety of clients including Sears, Blue Cross Blue Shield, and politicians running for election; sponsored films for the Art Institute of Chicago, the National Medical Association, and Eli Lilly; educational films for Encyclopaedia Britannica; and a documentary by Olin on the Jewish Brigade in World War II.
