This second volume in the Institute of Medicine’s series on America’s Aging explores the various productive roles that the growing number of elderly individuals can play in society through volunteer work. Some of the issues addressed include the main incentives and impediments to elderly volunteerism, the various forms of unpaid productive work and how they affect the health and well-being of the volunteer, and the recruitment of elderly volunteers that is done by various organizations. For policymakers, economists, sociologists, gerontologists, and social services agencies, this is an indispensable resource for the future.
