The book's title is also its framework: projects and essays are arranged according to scale. While Small and Medium address issues ranging from the domestic to the public, Large focuses on what Koolhaas calls the architecture of Bigness. Extra-Large features projects at the urban scale, along with the important essay What Ever Happened to Urbanism? and other studies of the contemporary city. Running throughout the book is a dictionary of an adventurous new Koolhaasian language - definitions, commentaries, and quotes from hundreds of literary, cultural, artistic, and architectural sources.
