Wonderful book store with an eclectic and varied selection of used photography books is the Book Barn, in East Lyme, CT. (Niantic). One of New England's best used book stores and a destination in itself. (Many cats, goats, three locations, multiple buildings filled with.... everything.) Don't go with an expectation to run in and grab something, though the various subjects and types of books are well organized and displayed - it's just too much fun to wander through. - Good wine merchant down the road as well.
