This booklet assembles information on 28 programs which have been used effectively by discussion groups throughout the country and are available to others in printed or audiovisual form. Its purposes are to alert those planning community adult education programs to a variety of approaches and materials and to serve as a source of information for community leaders or librarians who plan adult education activities. The booklet describes the characteristics of each program and appraises its overall values; analyzes the materials available for the leader and participant; and indicates the level of its appropriateness to meet varying age and interest needs. The programs listed are those considered particularly effective for a series of meetings of informal groups. They have a common objective of promoting a discussion situation which has a maximum potential for study and reflection, for growth in understanding and an exchange of ideas, and for development of a continuing interest in a subject field. The programs discussed are of two types: (1) book centered, and (2) subject centered, which use films, recordings, and tapes in addition to books. Among discussion programs included are: "Armament and Disarmament,""Contemporary Moral Issues,""Parenthood in a Free Nation,""Readings in Economics and Politics," and "Discovering Modern Poetry". (se)
