This portable book takes readers on a tour of American architectural treasures of the twentieth and twenty-first centuries. It provides the practical information-addresses, phone numbers, visitor hours, maps-needed to experience them at first hand-of 262 landmark buildings and explains why each will reward a visit. The accompanying descriptions offer new insights about the buildings and designers of this vital part of the American heritage. Among the new buildings included in this edition are Walt Disney Concert Hall (Frank Gehry), Seattle Library (Rem Koolhaas), American Folk Art Museum (Tod Williams/Billie Tsien), Contemporary Arts Center (Zaha Hadid), Milwaukee Art Museum (Santiago Calatrava), and the 'Solar Umbrella' House (Larry Scarpa/Angela Brooks).
