An area of research in which sociologists and historians would seem to share a rather obvious concern is that of social change. In his presidential address before the joint meeting of the Canadian Historical and Canadian Political Science Association, S. D. Clark emphasized this. "We cannot become students of change," he said, "without becoming historians. It is only by looking at what has happened to societies of the past, and over time, that the sociologist can derive the data on which to build his principles of social change." That is to say that the study of social change requires recognition of processes in time and must deal, insofar as time past is involved, with evidence that is historical. The student of social change must become a historian and the historian, insofar as he is interested in understanding and interpreting general processes, must become a social scientist. When, however, one searches the literature for particular studies of historical social change, one's findings are meager indeed, especially if one's standards, theoretically and methodologically, are reflective of those of contemporary social science, and one's historiographical standards, of contemporary history. If, in addition, one is searching for social change studies of a particular national history, then the material is even more limited. For this reason I have expanded this review, which was originally concerned with the American nineteenth century only, to include two studies of English history, because these two studies include important theoretical and methodological contributions to the study of history and social change in America.
