Book excerpt: This book is intended both as supplementary reading for courses and as a practical guidebook for individuals and programs interested in reducing prejudice and improving intergroup relations. It provides the only comprehensive review and compilation of techniques of improving intergroup relations. There's a huge amount of literature on the causes and nature of prejudice, reflecting great interest in the topic, but the literature on prejudice reduction is more scattered, spread across a range of theoretical and applied sources. This book brings these literatures together with an emphasis on helping to elucidate what works and why.
