In the age of the e-reader, it's easy to find specific titles. Sometimes, though, you want to leisurely thumb through a few paperbacks to figure out what you want. That's where this charming 42-year-old Park Hill co-op comes in. Its three stories are packed with new and previously loved tomes—classics, cookbooks, children's standbys, you name it—categorized by genre. Members ($15 per year for individuals, $20 for families) get 10 free used volumes annually and can trade in their own books for credits; guests can score hard copies at bargain-bin prices. For extra inspiration, visit the basement, where opening lines from beloved literary works are scribbled graffiti-style on the walls.
