Koolhaas, Dutch architect, author (Delirious New York) and cult figure, wants architecture to be ""a chaotic adventure,"" and this massive tome certainly is. Created with Toronto-based designer Mau, it's a huge collage splicing freewheeling essays, diary excerpts, photographs, architectural plans, sketches, cartoons and surreal montages of images. There's also a running glossary of Zen-like definitions, plus fables and parables intended to shake modern architects out of conventional thinking and to dispel urban despair. In one essay, Koolhaas admires Japan's metabolist movement, which fuses organic, scientific, mechanistic and romantic vocabularies. That approach seems compatible with his own innovative, eclectic vision as head of the Dutch firm Office of Metropolitan Architecture (O.M.A.), whose houses, villas, office towers, libraries, colleges, cultural complexes and other projects are showcased here. While some readers may be mystified by a nonlinear hodgepodge, architects, planners and designers will find this frequently outrageous assemblage a provocative repository of ideas. Author tour. (Mar.)
