Stephen Ware (Kansas) has published the third edition of the Concise Hornbook on ADR, information here and here. The third edition is substantially expanded and updated since the second edition appeared in 2007. Description:

This book provides a clear and reliable statement of the law and concepts central to ADR (arbitration, negotiation, mediation, and other processes). Its thorough coverage of arbitration law renders this challenging and rapidly-changing body of statutes and case law accessible to the student or lawyer. The chapters on negotiation and mediation treat the subjects from the perspectives of theory, practice, and legal doctrine.
