I give a list of some of the best online references in the latest update at http://www.mathpuzzle.com/ . Part of it is an excellent online book by Silvio Levy. And I link to other stuff. For example, the New York Times will have a new puzzle section, beginning May 6th. For anyone that would like to sign up for my mailing list, it's at http://tech.groups.yahoo.com/group/mathpuzzle/ Ed Pegg Jr.
