This book deals with reputation as a socio-cognitive mechanism able to strengthen collective action and promote social order, both in social systems and in artificial systems, such as online communities. In the book, the reader can find a thorough survey on reputation in many disciplines, a sound socio-cognitive theory of reputation, and some agent-based simulations that allow one to appreciate the theory put forward by the authors.
