Many historical maps are now accessible on the World Wide Web and the number increases all the time. The course consists of four sessions on what is available and how it can be accessed. All that is needed is a basic familiarity with web-browsing. The intention is for course members to then go off for the next four weeks researching maps that interest them. The final two sessions will be a visit to the Map Room at the University Library (subject to confirmation) and a final session in which members can present the results of their research. There will be a class website.
