When Rahm Emanuel takes over City Hall in May, the post-Daley era will officially begin! But how will official history treat the Mayor’s tenure? A good place to turn for answers is the Encyclopedia of Chicago. The massive reference book first published in 2004 is an effort to take stock of the news, ideas and culture that constantly redefine Chicago. Via research from scholars and journalists the Encyclopedia covers everything - from political conventions to polka and pollution! Jim Grossman, one of the editors of the book, joined Eight Forty-Eight from Washington D.C. where he's executive director of the American Historical Association.
