Five research reports are presented as key components of a comprehensive inquiry into the feasibility of expanding nonprison correctional options in California. The companion volume to this sourcebook is 'A New Correctional Policy for California: Developing Alternatives to Prison,' which presents recommendations. The specific objectives of the sourcebook are to (1) review existing programs which serve as alternatives to prison, including victim restitution and community service options; (2) assess the appropriateness and suitability of these alternatives, especially in the context of present prison populations and custody status necessary to ensure public safety; (3) identify the types of persons best served by these alternative programs; (4) recommend statutory changes needed to accomplish the expanded use of community alternatives; and (5) identify related costs of these alternatives and the relationship of these costs to benefits derived. The five research projects consisted of a review of existing and proposed alternatives to prison at the national and international levels; analysis of crime, criminal justice, and prison population trends in California; survey of existing postconviction alternatives in California, with emphasis on those available for convicted felons; survey of attitudes toward alternatives by local and State officials; and analysis of relevant legislation in California and other States. The data assembled is essential in clarifying policy issues and defining limits of various strategies to increase the use of nonprison sentencing and correctional options. The sourcebook also provides a useful compendium of information for those desiring basic data on alternatives to prison. Data and references accompany each research presentation.
