The Pendergast Machine
Dorsett, Lyle W. The Pendergast Machine. New York: Oxford University Press, 1968.
The Pendergast Machine is an expansion on Lyle Dorsett's master's thesis from the University of Kansas City, and is the earliest scholarly work to offer a comprehensive examination of the machine from its earliest days to its emerging statewide influence and its eventual collapse in 1939. Also included is a short but helpful bibliographic essay and ward maps that clarify the locations where the machine built its power base.
