This collection contains sketches, manuscripts, printed music and writings by George Cacioppo, American composer, founder of the ONCE group, and faculty member at the University of Michigan.
The collection contains sketches, manuscripts, printed music and writings by George Cacioppo, as well as correspondence (business and family), press clippings, programs and ONCE Festival memorabilia. The materials were arranged in logical sequence rather than "original order" so that research and performance of the materials would be facilitated. Details of the series arrangement have been provided below. Books and music by others have been removed from the collection, but lists of these materials have been retained. Many of Cacioppo's manuscripts were reproduced in different ways. The term "reproductions" was used in the finding aid to refer to ozalid copies and photocopies. Duplicates of the reproductions were removed.
