The Software Agents Mailing List is devoted to the issues of software
agents, personal digital assistants, software robots, knowbots,
intelligent interface agents, etc. The term agent is ill-defined and
because of this the scope of this mailing list will also be somewhat
ill-defined. However, it should be restricted to software agents as
opposed to hardware (robots) and human agents (your travel agent).
(Although the interface from software agents to other agents is fair
game.) The list was begun in 1994 by Ray Johnson, then at the Lockheed
Palo Alto AI Center and now at Sun. In the Fall of 1996 it moved to
UMBC.
