Justice Information Center. This site of the National Criminal Justice Reference Service, the clearinghouse for the U.S. Department of Justice and the Office of National Drug Control Policy, lives up to its claim to be “one of the most extensive sources of information on criminal and juvenile justice in the world.” The site’s materials are organized by major categories, such as corrections, courts, crime prevention, criminal justice statistics, drugs, and juvenile justice. Within each category are libraries of documents and reports as well as links to related Web sites. Select “Drugs and Crime,” for example, and you can download any of a number of reports and fact sheets on drug-related crime.
