This pamphlet on taking action in the community is the third of 16 in a series to provide leaders in adult activities with sound introductory material to give practical help in using a method of adult education or working in a particular area. Its objective is to help leaders plan and carry out a constructive program of social change. Eleven articles and how-tos are included. "Initiating Social Action,""Mobilizing Organizations," and "Mobilizing the Neighbors" suggest attitudes and methods helpful in beginning the job of working with others and discovering people who are likely to cooperate. "Recommended Methods" is a checklist of techniques that experts from nine fields find most helpful in presenting their aims and programs to community groups. The article "When People are Ready" shows specific ways to capitalize on a community's wish to solve its problems. "Community Apathy" is intended to help leaders see whether their analysis of community needs, plans, and techniques are adequate. Action groups are the focus of "From Ideas to Action.""Phases of Community Action" is a chart that provides a key to overall planning. "Counter-Attack" and "A Quick Look Into Conflict" help to anticipate difficulties and prevent emergencies as programs begin to affect the community. Attitudes of conformity or unthinking acceptance of things as they are are considered in "The Lost Art of Controversy." A bibliography is provided. (YLB)
