The Encyclopedia of Chicago has everything in it to engage the most curious historian as well as settle the most boisterous barroom argument. If you think you know how Chicago got its name, if you have always wondered how the Chicago Fire actually started and how it spread, if you have ever marveled at the Sears Tower or the reversal of the Chicago River--if you have affection, admiration, and appreciation for this City of the Big Shoulders, this Wild Onion, this Urbs in Horto, then The Encyclopedia of Chicago is for you.

Developed by the Newberry Library with the cooperation of the Chicago Historical Society, this is the definitive historical reference on Chicago and its environs. It brings together hundreds of historians, journalists, and experts on everything from airlines to Zoroastrians to explore all aspects of the rich world of Chicagoland, from its geological prehistory to the present.

The main section comprises more than 1,400 entries, covering the neighborhoods and suburbs of the region, Chicago's ethnic groups, the city's cultural institutions, technology and science, architecture, religion, immigration, transportation, business history, labor, music, health and medicine, and hundreds of other topics.

The Encyclopedia also encompasses eight of the counties surrounding the city as well.  Thumbnail maps pinpoint Chicago neighborhoods and suburban municipalities and are complemented by photographs and thematic maps that bring the history of metropolitan Chicago to life. Additionally, contributors provide lengthy interpretive essays that take a long view of such topics as the built environment, literary images of Chicago, and the city's often rabid sports culture.

The Encyclopedia also offers a comprehensive biographical dictionary of more than 2,000 individuals important to Chicago history and a detailed listing of approximately 250 of the city's historically significant business enterprises. A fascinating insert features a timeline of Chicago history and photo essays exploring nine pivotal years in this history.
