Book excerpt: Completely revised and updated, AIA Guide to Chicago, Second Edition is the liveliest and most wide-ranging guide ever written about Chicago's architecture. More than a thousand individual buildings are featured, along with more than four hundred photos-many taken expressly for this volume-and thirty-five specially commissioned maps. The book is arranged geographically so that the user, whether Chicago citizen or visitor, can tour each area of the city as conveniently as possible. Building descriptions focus on the illuminating-but easily overlooked-details that give the behind-the-scenes, often unexpected story of why a building took the shape it did. And in the best Chicago tradition, this guide does not shy away from opinions where opinions are called for. Comprehensively researched, meticulously written, and more than thorough.
