Since it was first published in 1993, the Sourcebook for Research in Music has become an invaluable resource in musical scholarship. The balance between depth of content and brevity of format makes it ideal for use as a textbook for students, a reference work for faculty and professional musicians, and as an aid for librarians. The introductory chapter includes a comprehensive list of bibliographical terms with definitions; bibliographic terms in German, French, and Italian; and the plan of the Library of Congress and the Dewey Decimal music classification systems. Integrating helpful commentary to instruct the reader on the scope and usefulness of specific items, this updated and expanded edition accounts for the rapid growth in new editions of standard works, in fields such as ethnomusicology, performance practice, women in music, popular music, education, business, and music technology. These enhancements to its already extensive bibliographies ensures that the Sourcebook will continue to be an indispensable reference for years to come.
