The Citizen Action Encyclopedia provides basic information on the activities and significance of the people, organizations, and events that comprise the history of American citizen activism in the 20th century. Containing almost 300 cross-referenced entries and 50 illustrations, the encyclopedia includes individuals, groups, and movements that achieved both national standing and significant success in altering the political, legal, social, or economic structure of the United States. The encyclopedia is the first single-volume reference work to cover the entire spectrum of American activism in the last century, describing groups and activists of both the Left and the Right. The book also offers broad general entries that put the debates on such issues as the environment and abortion policy into balanced perspective.
