Technology has changed considerably since the second edition of the guide was printed. While records continue to be a critical component of the operation of a law enforcement agency, the changes in technology are proving to be a welcome addition to the tools a records manager may have to keep pace with the increasing demands for records storage and retrieval. The manual will provide a glimpse of new technologies and systems that are available to law enforcement today. Since the last edition was published, there have been significant changes in the legislation, several of which require reporting of specific crimes to the California Department of Justice. Those legislative changes and case law decisions affecting records managers have been included in this edition. We have expanded the scope of our records manual and include information on new justice data systems which are available to all California law enforcement agencies.
