Wisconsin Center for Film and Theater Research
The Wisconsin Historical Society and the University of Wisconsin-Madison have joined together to create the Center's tremendous Film, Theater, & Radio and TV collections (including the Ed Sullivan Collection) which contain many prized treasures from the past. You can get an idea of their immense holdings via their archives catalog (ArCAT) - the link is found to the bottom left of the page. As an online viewer, while most of these resources will not be accessible to you, certain selections have been digitized for you via the "Featured Collections" link with its aim to " provide authoritative scholarly websites focused on WCFTR collections that combine well-researched information with digitized selections of primary-source materials from our archives." Some examples of these "Featured Collections" include "The Golden Age of Television", "The Early Career of Robert Altman", "The Papers of Edith Head" (costume designer), among others.
