This book constitutes the refereed proceedings of the 14th International Conference on Automated Reasoning with Analytic Tableaux and Related Methods, TABLEAUX 2005, held in Koblenz, Germany, in September 2005. The 18 revised research papers presented together with 7 system descriptions as well as 4 invited talks were carefully reviewed and selected from 46 submissions. All aspects of the mechanization of reasoning with tableaux and related methods are focused: analytic tableaux for various logics, related techniques and concepts, new calculi and methods for theorem proving in classical and non-classical logics, systems, tools, and implementations. It puts a special emphasis on applications of tableaux and related methods in areas such as, for example, hardware and software verification, knowledge engineering, and semantic Web.
