There have been three accruals. The first and principal accrual of the collection was compiled by his close friend and admirer, Frank Holliday. During the 1960s the composer agreed to allow Holliday to tape record him playing his own compositions. Their correspondence over a forty year period as well as the audio reels and cassettes are the core of this collection. The reels have been reproduced on audio cassettes for use by researchers. The number of audio cassettes listed above refers only to original cassettes.
