This resource guide, prepared by the Cook County Sheriff's Youth Services Department in Maywood, Illinois, contains information about five evolving styles of youth service delivery strategies, i.e., youth participation, youth advocacy, development of a comprehensive youth policy, youth development policy design, and delinquency prevention through community development. The guide is divided into three sections: (1) Strategies: Descriptions and Bibliographies, defining the concepts providing an overview, and suggesting related resources; (2) Information Resources, including a list of clearinghouses and youth-oriented newsletters; and (3) Supplementary Bibliographies, focusing on the areas of planning, assessment, evaluation, research, training, and funding.
