I just put online the paper on wikis that I presented on November 7 at a conference on electronic publishing in Karlovy Vary, Czech Republic. It gives a lot of credit to Larry Sanger and Jimmy Wales.

If you have a pointer to any earlier paper on wikis appearing in a scholarly/scientific journal or at a conference, I'd like to know.
