Extraordinary Groups has had a storied history of excellence over multiple editions. Now available from Waveland Press at the start of its fifth decade of availability, its interdisciplinary approach to groups engaged in unconventional lifestyles makes it a popular textbook choice in hundreds of college courses across the social sciences, including anthropology, religion, history, and psychology. Written by sociologists, using and illustrating sociological principles, the book is appealing because it is descriptive and explanatory rather than analytical. Descriptions of the groups are interwoven with basic sociological concepts, but systematic analysis and inductive reasoning are left to the discretion of the instructor. Extraordinary Groups is a compelling overview of the broad tapestry of social life that constitutes the United States. The illustrated, full-featured Ninth Edition includes a glossary and end-of-chapter key terms, sources on the Web, and selected readings.
