As Howard Gillette Jr. points out in his introduction to our first selection in this review, "Central to the timing of this book is the transitional nature of urban history as a distinctive field of study"(l). And yet, from the time of its dramatic growth in the 1960s, American urban historiography has always been in a state of transition. Innovative methodologies and theories are still being advanced by those on the forefront of pioneering efforts. But despite the multiplicity of hypotheses, directions and conclusions which were pursued in the 1970s, most urban historians felt increasingly secure about the legitimacy of their collective endeavour as the decade progressed. The birth in 1974 of the Journal of Urban History, the numerous serial publications in urban studies launched by academic presses, and the advent of a variety of university programs in the field all seemed to be more than hopeful signs. Urban historians were already consolidating their positions and gathering into rival schools of thought. Back in 1971, when Stephan Thernstrom boldly challenged the very legitimacy of urban studies, his voice stood out as one of lonely dissent. But now, it appears, the academic consolidation which urban history achieved in the 1970s is facing formidable criticism from several fronts. Notable practitioners such as Theodore Hershberg of the once- thriving Philadelphia History Project, or Sam Bass Warner Jr., who formerly was dedicated to the reformist potential of urban history, have reached bleak conclusions concerning the survival of their respective approaches. Stephan Thernstrom's critique is no longer quite so isolated. But this new collection of fourteen essays has not been compiled to examine a sub-discipline entering a period of crisis or decline; instead, these articles serve to identify, through their retrospective examinations of past work, new methodological and ideological directions for American urban historiography. The authors' respective messages strike an optimistic chord. Their advocacy of new interpretative approaches seeks to build on past accomplishments rather than to abandon failed efforts.
