The materials from WFAA and WBAP accumulated through the decades in which those stations employed live radio orchestras, and are a major resource for performance, study, and local and national broadcasting history. Don Gillis, whose collection is also housed in the UNT Music Library, assisted in the acquisition of the WBAP collection.
The popular song collection consists primarily of piano-vocal scores, often with chord symbols and even chord grids for guitar and/or ukulele. These materials are of interest from numerous angles, including the development of the American Songbook and canon of "standard" jazz tunes, propaganda from the two World Wars and Great Depression, the status of immigrant and ethnic groups, and other topics. Many titles are quite rare, and in many cases, the collection includes the more obscure works even of the better-known composers and lyricists.
