This book constitutes the refereed proceedings of the 9th International Conference on Logic Programming and Nonmonotonic Reasoning, LPNMR 2007, held in Tempe, AZ, USA in May 2007.
The 18 revised full papers, five revised poster papers, and seven system descriptions presented together with two invited papers were carefully reviewed and selected for presentation. As a forum for exchanging ideas on declarative logic programming, nonmonotonic reasoning, and knowledge representation, LPNMR encompasses theoretical studies, design and implementation of logic based programming languages and database systems, and development of experimental systems. This volume also includes the results of this year's answer set programming competition.
