The Ambassador Auditorium Collection contains the files of the various organizational departments of the Ambassador Auditorium as well as audio and video recordings. The materials cover the entire time period of April 1974 throughMay 1995 when the Ambassador Auditorium was fully operational as an internationally recognized concert venue. The materials in this collection cover all aspects of concert production and presentation, including documentation of the concert artists and repertoire as well as many business documents, advertising, promotion and marketing files, correspondence, inter-office memos and negotiations with booking agents. The materials are widely varied and include concert program booklets, audio and video recordings, concert season planning materials, artist publicity materials, individual event files, posters, photographs, scrapbooks and original artwork used for publicity. Many of the print materials include handwritten comments from office personnel and administrators, and many of the artist photographs are autographed. Since the various office personnel maintained their own files, and the same information was often needed in more than one office at a time, the collection contains duplicate copies of many items. Although efforts were made to eliminate duplicate material from the same file or the same series, duplicate copies of items exist among the files from different offices. In an effort to maintain the original content of these files, the cross-file duplicate items were retained in the collection.

The collection was processed under the auspices of the Council on Library and Information Resources and is generously supported by the Andrew W. Mellon Foundation.
