Book excerpt: ""Which neighborhood?" It's one of the first questions you're asked when you move to Chicago. And the answer you give - be it Bucktown, Bronzeville, or Bridgeport - can give your inquisitor a good idea of who you are, especially in a metropolis with so many different neighborhoods and suburbs to choose from." "Many of us know little of the neighborhoods beyond those where we work, play, and live. This is particularly true in Chicagoland, a region that spans over 4,400 square miles and is home to more than 9.5 million residents. Now, historian Ann Durkin Keating's compact guide, drawn largely from the bestselling Encyclopedia of Chicago, brings the history of Chicago neighborhoods to life."--BOOK JACKET.
