Several encyclopedias overview the contemporary system of criminal justice in America, but full understanding of current social problems and contemporary strategies to deal with them can come only with clear appreciation of the historical underpinnings of those problems. Thus, this four-volume work surveys the history and philosophy of crime, punishment, and criminal justice institutions in America from colonial times to the present. It covers the whole of the criminal justice system, from crimes, law enforcement and policing, to courts, corrections and human services. Among other things, this encyclopedia will: explicate philosophical foundations underpinning our system of justice; chart changing patterns in criminal activity and subsequent effects on legal responses; identify major periods in the development of our system of criminal justice; and explore evolving debates and conflicts on how best to address issues of crime and punishment. Its signed entries provide the historical context for students to better understand contemporary criminological debates and the contemporary shape of the U.S. system of law and justice.
