Tony-- Since I end up trying to get at least half a dozen out of print books a year, I've found university bookstores to be very helpful. But right here in Hartford we also have a terrific resource for Twain: the aptly-named Jumping Frog Bookstore, 585 Prospect Ave., West Hartford (okay, so it's West Hartford, a town distinguished only by being Noah Webster's birthplace and its law prohibiting outdoor clotheslines). The number is 860-523-1622; hours are 12-8 daily. Kathy O'Connell
