This thoughtful collection of original work by eminent sociologists and criminologists was compiled to honor Henry D. McKay, the pioneer investigator and collaborator with Clifford R. Shaw. Among the traditions most basic to both continuity and change in criminological research and theory, one of the most important is that associated with Shaw and McKay and the "Chicago school" of urban sociology. So great has been its impact that even the most recent theoretical formulations draw upon it for support or in criticism. Reassessing the "Shaw and McKay tradition," the contributors to this volume pursue critical and emerging issues in the study of crime and delinquency.
