This book is an ambitious attempt to map the main changes in the criminal justice system in the Victorian period through to the twentieth century. Chapters include an examination of the growth and experience of imprisonment, policing, and probation services; the recording of crime in official statistics and in public memory; and the possibilities of research created by new electronic and on-line sources; an exploration of time, space and place, on crime, and the growth internationalisation and science-led approach of crime control methods in this period.Unusually, the book presents these issues in a way which illustrates the sources of data that informs modern crime history and discusses how criminologists and historians produce theories of crime history. Consequently, there are a series of interesting and lively debates of a thematic nature which will engage historians, criminologists, and research methods specialists, as well as the undergraduates and school students that, like the author, are fascinated by crime history.
