This guidebook is part of a series of publications about public/private partnerships. The guidebook has a three-fold goal: (1) Spark the aging network's interest in developing and expanding public/private partnerships in volunteerism; (2) Provide guidance on how to create such partnerships; and (3) Share examples of partnerships that other aging network organizations have tried. The book is organized into four chapters. Chapter 1 introduces the world of volunteerism partnerships and the benefits of these arrangements. Chapter 2 discusses the types and ranges of partnership formats, while chapter 3 looks at the challenge of enlisting volunteers to work with seniors and describes the steps involved in designing a partnership strategy. Chapter 4 provides fuller descriptions of some of the successful partnerships in volunteerism. Although the majority of examples used throughout the guidebook are of programs and partnerships with businesses, much of the information and advice can apply to other potential partners, including schools, religious institutions, educational, professional and trade associations. Although not inclusive in its material, the guidebook should stimulate those in the aging network to develop their own initiatives and programs. Three appendices offer information on additional resources, sample volunteer forms, and the book's authors. (RJM)
