The authors use their particular program as an empirical blueprint for principles undergirding the successful use of volunteers as extensions of professional social service staff. The case-aide handbook appended to the volume provides a "quick prescription" formula for how this volunteer program was made viable and how these techniques can be adapted to other programs. In the new and enlarged edition of , the authors tell about "whatever happened to..." the case aides in their program, based on the responses to a questionnaire they designed and mailed to 100 of these men and women. Models for Volunteer/Professional Partnerships are defined and illustrated with creative and innovative volunteer programs reviewed by Feinstein and Cavanaugh. These programs serve many different populations, including: alcoholics, the elderly, the mentally ill, the retarded, abusive parents, and the terminally ill.
