When bosses ruled Philadelphia : the emergence of the Republican machine, 1867-1933 by Peter McCaffery.
This is the most thoughtful and intensive analysis of the emergence of a political machine of any written in recent years. McCaffery has mastered the theory and historiography of the political machine in general and applied this to a wealth of sources in Philadelphia. His questions are rigorously formulated, exhaustively researched, and convincingly stated.- back cover, Terrence J. McDonald, University of Michigan
