Book excerpt: Counterculture, while commonly used to describe youth-oriented movements during the 1960s, refers to any attempt to challenge or change conventional values and practices or the dominant lifestyles of the day. This fascinating three-volume set explores these movements in America from colonial times to the present in colorful detail. "American Countercultures" is the first reference work to examine the impact of countercultural movements on American social history. It highlights the writings, recordings, and visual works produced by these movements to educate, inspire, and incite action in all eras of the nation's history. A-Z entries provide a wealth of information on personalities, places, events, concepts, beliefs, groups, and practices. The set includes numerous illustrations, a topic finder, primary source documents, a bibliography and a filmography, and an index.
