The Bookworm is one of the few remaining non-chain bookstores left on this planet. Friendly, knowledgeable staff--They actually have HEARD of Faulkner and Hemingway. Beautiful kids' books section. Stay away from the big chains--we want The Bookworm here forever!
I have always been able to find everything I need at Barnes & Noble. When my daughter was in college and needed to do research this was the first place we looked. It has a huge reference section as well as a very good selection of recent fiction and non-fiction.
SELLER in the Old Market. What a joy that an independent shop remains! Specializes in spirituality, new age. I especially like the special-interest gatherings they organize. A proverbial breath of fresh air!
