Wrigley Field is one of a handful of sports stadiums to have transcended its athletic purpose to become a true American landmark. Nestled in its neighborhood on the north side of Chicago, the park may be a throwback to a bygone era of baseball, but a recent renovation has positioned it for a long future. Gregory H. Wolf has edited Wrigley Field: The Friendly Confines at Clark and Addison, a new volume from the Society for American Baseball Research (SABR). Wolf is a professor of German studies and holder of the Dennis and Jean Bauman Endowed Chair in the Humanities at North Central College in Naperville, Ill. He is a member of SABR, for which he has edited nine books.
