The emphasis in the selectively annotated bibliography is primarily on nonvocational adult education. The 1,756 entries are grouped into four large categories, with subdivisions: general (bibliographies, yearbooks and directories, encyclopedias, and periodicals); social and educational background (general works, history of education, and mass media); history and organization of adult education (general historical and descriptive surveys, particular movements and organizations, special aspects, and administration); and theory and method (general social and educational theory, theory of adult education, methods of teaching and study, and particular academic subject areas). Each of these is then divided into a number of subtopics. Most of the items are annotated. There are some cross-references, and many references to works not included in the bibliography. Entries have been restricted to works published before the end of 1972, but exceptions have been made for a few major works published since that date. Author and subject indexes are included. (PR)
