There is a great website associated with the Festival of Maps that is taking place through February 2008. The site offers a chance to view sites via a map, search for specific content/events and browse by different map types. If you are going to Chicago in the near future definitely check out this great resource to plan your tour of sites participating in the Festival of Maps. Keep an eye out for a video episode in late November after we get back from the SSHA conference in Chicago.
