4. Watchung Booksellers, Montclair, N.J.
Watchung Booksellers is the favorite bookshop of "Travels in Siberia" author Ian Frazier. "There's a daily rhythm to the life of books," he wrote of the store. "Kids are running around.... and there are the sounds of conversations about books, and the humming quiet of the browsers, and the crisp tearing and folding of gift-wrap paper at the counter, and it smells like books."
