The focus of the David Sarnoff papers is the original David Sarnoff Collection assembled by Sarnoff to celebrate his career. However, the papers also include the extensive photographic, publicity, and administrative files created by his staff at RCA and a substantial audiovisual component. In contrast to the documents and photographs, which have a clear distinction between the original collection and later additions, the origins of the audiovisual material is poorly documented. They are there therefore described separately, but most were probably part of the original David Sarnoff Collection.
