A criminal law library offers a wide range of resources, including information concerning federal and state statutes, criminal law procedures, codes, treatises, and judicial practices, according to the Judicial Council of California and the Georgetown Law Library. Electronic criminal law libraries are available from the CEB program of the University of California.
Online criminal law libraries are repositories of criminal law that make law documents available for public viewing. The contents of these libraries include the actual laws applicable to a specific jurisdiction, criminal procedure, court rules pertaining to arrests, evidence and legal proceedings in a criminal case, and specific case law in the state, as the Massachusetts Court System reports. Libraries also provide students, professionals and the general public with legal resources pertaining to criminal justice, including research papers, policy documents, forensics information, police and criminal justice statistics, and supplementary resources about legal ethics and legal education, as is the case with the Criminal Law Library of New York City.
Some law libraries provide users with several supplemental publications, such as law journals, government reports, penal codes and commentaries, according to the D'Angelo Law Library of the University of Chicago. Electronic law libraries serve as compendiums of legal cases, codes and forms applicable to state or federal criminal law, as is the case with the CEB program of the University of California.
