Book excerpt: David Millers expanded third edition makes it the definitive source on collective behavior and collective action. Up-to-date and meticulously researched, this popular volume continues to provide a systematic overview of theory and research. Each topic is meaningfully linked to the appropriate theories of collective behavior (mass hysteria, emergent-norm, and value-added perspectives) and collective action (social-behavioral interactionist, resource mobilization, and value-added perspectives). Rumor, mass hysteria, fads and fashion, UFOs, sports, migrations, disasters, riots, protest, and social movements are among the topics presented in a unique side-by-side presentation of the two disciplines. In an engaging, accessible style, Miller offers detailed discussion of classic sociological studies interspersed with intriguing modern-day examples that students will enjoy reading. His thorough topical treatment effectively reduces the need for outside readings.
