"Ragtime: An Encyclopedia, Discography, and Sheetography" is the definitive reference work for this important popular form of music that flourished from the 1890s through the 1920s, and was one of the key predecessors of jazz. It collects for the first time entries on all the important composers and performers, and descriptions of their works; a complete listing of all known published ragtime compositions, even those self-published and known only in single copies; and a complete discography from the cylinder era to today. It also represents the culmination of a lifetime's research for its author, considered to be the foremost scholar of ragtime and early 20th century popular music. Rare photographs accompany most entries, taken from the original sheets, newspapers, and other archival sources. "Ragtime: An Encyclopedia, Discography, and Sheetography" will be a standard reference for anyone interested in the history of jazz.
