Under each subject heading, the citations are listed by publication date and accession number. Some citations may appear in more than one subject category. However, some documents are added to the data base regardless of publication date because they are regarded as classics in the criminal justice field. There are also no date restrictions on reports of Government-funded research. Paper copies of the list are available upon request, but most subscribers prefer to receive copies by e-mail.
Visitors can make appointments by calling the library during normal business hours.
Due to the specialization of the collection, professional library staff are on duty to assist patrons and locate materials. A photocopy machine is available for visitors who wish to make photocopies of library materials. Staff are available to answer questions regarding search strategies, downloading, or linking with other data bases. There is a fee for interlibrary loans. This fee is waived for Federal and State government libraries, criminal justice agencies, and law enforcement officers.
