the world in a square - View this location on map 'Two Starbucks, two drugstores and several chain restaurants may call Harvard Square home, but so do quirky street performers, plotting chess masters, teenage Goths and, especially, independent bookstores. The Harvard Book Store (617-661-1515), above, has an outstanding selection of general-interest books and criticism and a solid used-book section. A half-block away, the Grolier Poetry Book Shop (6 Plympton Street, 617-547-4648) is a destination for poets and scholars worldwide. For travel buffs, the Globe Corner Bookstore (28 Church Street, 617-497-6277) sells maps, guides, travel literature and coffee-table books; and if you're looking for Camus or Cervantes in the original language, head to Schoenhof's Foreign Books (76A Mount Auburn Street, 617-547-8855).
