Dear John, Although certain parts of the Twain house are undergoing restoration right now (primarily, I think, the downstairs library), as far as I know it's open for tours. As someone doing some serious research, you might call ahead to see if you can get someone on staff or a top-notch docent to take you through. Call (860) 247-0998 between 9 and 5. John Boyer is the director, and he's a good, smart guy. Kevin B. could probably help you with the New York end. I know the forum did a birthday walking tour last November. Good luck!
