Massachusetts Historical Society

The oldest historical society in the country (founded 1791), Mass Historical holds so many treasures it's hard to believe it. Documents and artifacts dating back to the beginning of the Massachusetts Bay Colony and the beginning of our country. One well-known treasure are the letters of John and Abigail Adams - some of which are available online. But the MHS library is open to the public, from 9:00 am to 4:45pm daily. Serious researchers should contact the resource librarian before visiting. MHS also installs exhibits periodically and has a calendar of lectures and talks on Massachusetts history.
