After the attacks on the World Trade Center, the question of how cities renew, rebuild, and remember has become ever more pertinent. By placing the event within a global, cultural, and historical context, and examining the ways in which cities around the world have rebuilt in the wake of natural and man-made disasters, the Van Alen Institute offers some possible answers to the question. Information Exchange explores a range of temporary and permanent public art and architecture projects built in the damaged cities of Berlin, Beirut, Kobe, Manchester, Sarajevo, Oklahoma City, and San Francisco by such firms as Germany's Schneider + Schumacher Architekten, New York's Eisenman Architects, Oklahoma City's Butzer Design Partnership, and Sarajevo's Ferhad Mulabegovic. At the center of Information Exchange is a roundtable discussion, Retread or Reinvention: How Cities Change after Disaster. Other entries include interviews with designers, artists, journalists, cultural programmers, and academics; comprehensive historical narratives in the form of timelines; and photographs of the cities' new buildings.
