This bibliography is a current source of information for researchers, practitioners, and planners interested in the older volunteer. The authors conducted an extensive search of material on the older volunteer, with emphasis on those works published between 1980 and 1991. After identifying approximately 700 sources, the authors selected nearly 400 for inclusion in this reference. The entries are grouped in seven topical chapters, and each entry includes a succinct annotation. Included are entries for books and articles on particular programs, characteristics of older volunteers, sources of statistical information, empirical research, and special population groups. Author and subject indexes conclude the work.
