GUIDE: Elliker, Calvin, 1949- Early imprints in the Thomas A. Edison Collection of American Sheet Music; D-23158 This collection, from the Music Library of the University of Michigan, gathers printed music originally published ca. 1790-ca. 1860. Thomas Alva Edison was a prolific collector of sheet music to support the activities of his phonograph company. The microfilm collection is based on -- and supplements -- the bibliographies of Oscar George Theodore Sonneck (revised by William Treat Upton) and Richard J. Wolfe, two of the most prominent reference works on early American music imprints. Roughly 15,000 items (both vocal and instumental music) are represented in this set, one of the largest single collections of pre-1861 sheet music in the U.S.
