Over 700 reference materials, songbooks, and recordings on pop, rock, country, folk, blues, and soul music from the 1950s to the present are listed. The bibliography was compiled because the study of popular music is becoming increasingly important to disciplines such as history, communications, and popular culture as well as music. Entries are listed alphabetically by author or artist under the following topics: reference works (encyclopedias, bibliographies, song sources, discographies, record reviews, record charts, and guides to rock collectibles), periodicals, history and criticism, literature by artists, songbooks, and the music business. Information under the topic of the music business includes music publishers' and distributors' addresses, careers in the music industry, and album cover and poster art. Library of Congress call numbers are included with the bibliographical information. An individual artist and group index is included. (KC)
