The collection contains approximately 250 musical works, of which more than 100 are manuscript facsimiles. Many works in the collection remain unpublished. Composers from both the Americas and Europe (particularly East Europe and Russia) are represented. Most of the pieces were composed by contemporaries of Cramer, and many were composed as a direct result of Dr. Cramer's activity. Many of the scores are inscribed by the composer or Dr. Cramer, or both. Most works are for piano and trombone; however, there are also pieces accompanied by organ, orchestra or band, as well as pieces for trombone alone. Also included in the collection are four boxes of correspondence with with composers, publishers, and other musicians, dating from 1947-1989.
