The Raymond Scott Collection was donated to the University of Missouri-Kansas City by Mitzi Scott, Raymond Scott’s widow, in 1993.

Housed in LaBudde Special Collections, the original manuscript collection, which encompasses much of Scott’s career until 1980, is organized into 11 series: manuscript music scores; published music; correspondence; news clippings; journals, diaries and scrapbooks; production notes; personal; engineering and inventions; miscellaneous; oversized schematics; and photographs. The strength of the collection lies in over 400 manuscript scores by Scott. They are in various stages of development including sketches, fragments and completed scores, which provide opportunities to see the progress of a work from a copy to a completed, published score. This is especially true with The Lute Song manuscripts. The collection also gives insight into the other side of Scott’s career – that of inventor and electronic music pioneer. There are 20 spirals and 36 disclosures to indexed inventions. Additionally, there are miscellaneous invention and engineering notes, and schematic drawings and diagrams. Other items of interest include journals, diaries and scrapbooks of Scott and his second wife, Dorothy Collins; personal and business correspondence; and several hundred photographs, including publicity and candid shots.

Addendum 1 consists of additional materials donated by Mitzi Scott in March 2012. Inclusive dates range from the 1930s through the 1980s with the bulk of material concentrated during the 1930s and 1940s. The addendum comprises biographical data, correspondence, professional career, projects and activities, notebooks, miscellaneous, music manuscripts, and photographs.

Addendum 2 consists of additional materials donated by Irwin Chusid in 2008-2009 (but processed after the first addendum was added). The addendum comprises a 1938 magazine with an article about Scott (and his brother Mark Warnow); a page from an unknown scrapbook documenting Scott playing at two dances in Summit, New Jersey; a photograph of Raymond Scott and His Quintet and the Pearl Sisters at the studio lot for Ali Baba Goes To Town; and color copies of a 1939 brochure featuring Scott’s drummer Johnny Williams.

Addendum 3 consists of additional materials donated by Irwin Chusid in 2017. The addendum comprises copyrights and contracts from Gateway Music for Scott and other musicians, magazines with articles about Scott, a few music scores, and additional photographs.

The audiovisual materials contain audio of the works and personal recordings of composer Raymond Scott. Spanning Scott's entire career, the collection contains recordings of his "Quintette", Your Hit Parade which featured Scott as orchestra leader, and his ground-breaking works in electronic sounds that have been used for the albums Manhattan Research and Three Willow Park: Electronic Music from Inner Space. Scott's work with Dorothy Collins is well represented in the collection. The collection also includes interviews with Scott and conversations that he recorded.
