If any of you bibliophiles are ever in Boston, take a trip to the New England Mobile Book Fair
http://www.nebookfair.com/ in Newton, MA. It's only about a mile or so inside Rte 128 in Newton Highlands and well worth the trip. It's strictly utilitarian (no comfy chairs or cafe) and the books are arranged by publsiher, but they always seem to have an excellent selection of everything.
