"The Sourcebook for Research in Music" - in this revised and greatly expanded second edition, is an invaluable guide to the researcher in navigating the vast proliferation of materials in music research. The editors emphasize English-language and recent sources, and also include essential materials in other languages. An opening chapter of introductory materials, including a list of common bibliographical terms with definitions, German and French bibliographical terms, and the plan of the Library of Congress and the Dewey Decimal music classification systems, is followed by seven bibliographical chapters, covering lists of sources as well as collective annotations that introduce and identify specific items.A reference tool containing varied information relating to research in music, the "Sourcebook" will serve as a classroom text and as a resource for individual music researchers, librarians, faculty members, students, performing and teaching musicians, and musical amateurs. Phillip D. Crabtree and Donald H. Foster are both retired from the faculty at the University of Cincinnati College-Conservatory of Music. D.Allen Scott is Associate Professor of Music History at Oklahoma State University.
