The Fissinger papers are arranged into three series, selected sacred works of Antonio Caldara, publications and compositions. The work of Antonio Caldara was the subject of Fissinger's Ph. D. dissertation and represents his research notes and copies of Caldara's music. There are also publications that included compositions by Fissinger or items he edited. Included is his work, Workbook of Music Fundamentals, published in 1959. The original compositions constitute the great majority of the collection and have been organized alphabetically. Almost all are handwritten works by Fissinger, with only an ocassional draft or final printed version. Much of the compositions are for sacred music.
