This book constitutes the proceedings of the 9th International Workshop on Distributed Algorithms, WDAG '95, held in Le Mont-Saint-Michel, France in September 1995. Besides four invited contributions, 18 full revised research papers are presented, selected from a total of 48 submissions during a careful refereeing process. The papers document the progress achieved in the area since the predecessor workshop (LNCS 857); they are organized in sections on asynchronous systems, networks, shared memory, Byzantine failures, self-stabilization, and detection of properties.
