The most obvious resources are the major international and national conferences on AI: the International Joint Conference on AI (IJCAI), held biannually in odd years, the European Conference on AI (ECAI), held biannually in even years, and the (American) National Conference on AI, organised by AAAI, which is held annually in the US except when IJCAI is held on the North American continent. In 1994, the eleventh ECAI conference was be held in Amsterdam, and the eleventh AAAI in Seattle, WA; in 1995, the fourteenth IJCAI will be held in Montreal, Canada. A brief look at the references on this paper will confirm that much of the work cited here appeared in these three conferences. The proceedings of all these conferences are readily available. Turning to more specialist conferences and workshops, there is the International Workshop on Distributed AI (IWDAI), which has been held more-or-less annually since 1979; the thirteenth such workshop was held at Lake Quinalt, WA, in July 1994. Unfortunately, the proceedings of IWDAI are not published regularly, and can be difficult to get hold of. In Europe, the workshop on Modelling Autonomous Agents in Multi-Agent Worlds (MAAMAW) is held annually; the sixth such workshop was held in Odense, Denmark, in August 1994. The MAAMAW proceedings are published regularly. Results of interest also appear in other workshops, for example the UK series on Cooperating Knowledge-Based Systems (CKBS), and the conferences on Cooperative Information Systems (CoopIS). The first International Conference on Multi-Agent Systems (ICMAS) will be held in San Francisco in July 1995; further details are not available at the time of writing. Turning specifically to theory, the fifth conference on Theoretical Aspects of Reasoning about Knowledge (TARK) was held in 1994. The European Workshop on Logics in AI (JELIA), and the International Conference on Knowledge Representation and Reasoning (KR&R) are other good sources of theory.
With respect to journals, there is obviously Artificial Intelligence; the IEEE Transactions on Systems, Man and Cybernetics has also had much useful material over the years. The only related specialist publications we know of are Robotics and Autonomous Systems the International Journal on Intelligent and Cooperative Information Systems (IJICIS).
