Did you know there were over 800 university history departments and historical organizations in the US and Canada? I didn’t either until I saw the directory at http://www.historians.org/pubs/directory/index.cfm .
You can browse by institution name, search by name, or search by degree type and state. Searching New Hampshire listed five results, with detail pages giving the address of the university and e-mail and Web contacts for the history department. The level of degrees offered by the department are also listed.
