Encyclopedia of the Blues 2-Volume Set [PDF ebook] 

The Blues Encyclopedia is the first full-length authoritative Encyclopedia on the Blues as a musical form. While other books have collected biographies of blues performers, none have taken a scholarly approach. A to Z in format, this Encyclopedia covers not only the performers, but also musical styles, regions, record labels and cultural aspects of the blues, including race and gender issues. Special attention is paid to discographies and bibliographies.
