Many service systems have fundamentally reoriented services by creating infrastructures that link resources from many parts of the community. This paper reviews 50 comprehensive community-based initiatives and describes their costs, results, and methods of finance. The overview defines comprehensive community-based initiatives and outlines governance arrangements, financing strategies, and accountability systems. All the models present potentially promising models for community change. For the most part, however, their experiences have not been documented in ways that will help policymakers or community leaders draw well-informed conclusions about costs, benefits, and the feasibility of implementation on a larger scale. A matrix of the initiatives highlights the 50 programs' arrangements for financial support and evaluation. Specific information on each program is provided. Information was gathered from descriptive information about the initiatives, evaluations conducted by or for the initiatives, and phone conversations with participants and evaluators. Appendices describe the methodology and list selected sources for the review of the initiatives. Information on the Finance Project and its available resources are included. (Contains 21 references.)
