Other NCJRS services are the publication of 'NIJ Reports,' a bimonthly journal of news and announcements pertaining to criminal justice; the issuing of 'Books in Brief,' 4-page summaries of significant criminal justice publications; and topical searches that develop a list of documents on particular topics. In addition to the general data base on criminal justice, NCJRS collects specialized information on juvenile justice, alternative dispute resolution modes, and justice statistics.
