Larsen, Lawrence H. and Nancy Hulston. Pendergast! Columbia: University of Missouri Press, 1997.
Although published more than 20 years ago, Pendergast! offers the most complete and best-documented biography of Tom Pendergast. It utilizes prison records and family correspondence that had not been publicly available for reference in prior publications. Beyond merely recounting the activities of the machine, the authors characterize important aspects of "Boss Tom's" family background, personality, and business connections. The work also incorporates numerous photographs.
