Architecture is a strange mixture of persistence and flux, an amalgamation of elements — some that have been around for over 5,000 years and others that were (re)invented yesterday. The fact that these elements change independently of each other, according to different cycles and economies, and for different reasons, turns each building into a complex collage of the archaic and the current, the site-specific and the standard, mechanical smoothness and the spontaneous. Only by looking at the elements under a wide lens can we recognize thecultural preferences, forgotten symbolism, technological advances, mutations triggered by intensifying global exchange, climatic adaptions, political calculations, regulatory requirements, new digital regimes, and, somewhere in the mix — the ideas of the architect that constitute the practice of architecture today. A collection of these essential elements into 15 books in a package launched at the 2014 Venice Biennale that allows us to look through a microscope at the real fundamentals of our buildings and see again the essential design techniques used by any architect, anywhere, anytime.

Preservation is Overtaking Us brings together two lectures given by Rem Koolhaas at Columbia University's Graduate School of Architecture, Planning and Preservation, along with a response (framed as a supplement to the original lectures) by Jorge Otero-Pailos. In the first essay Koolhaas describes alternative strategies for preserving Beijing, China. The second talk marks the inaugural Paul Spencer Byard lecture, named in celebration of the longtime professor of Historic Preservation at GSAPP. These two lectures trace key moments of Koolhaas' thinking on preservation, including his practice's entry into China and the commission to redevelop the State Hermitage Museum in St. Petersburg, Russia. In a format well known to Koolhaas' readers, Otero-Pailos reworks the lectures into a working manifesto, using it to interrogate OMA's work from within the discipline of preservation.

S, M, L, XL presents a selection of the remarkable visionary design work produced by the Dutch firm Office for Metropolitan Architecture (O.M.A.) and its acclaimed founder, Rem Koolhaas, in its first twenty years, along with a variety of insightful, often poetic writings. The inventive collaboration between Koolhaas and designer Bruce Mau is a graphic overture that weaves together architectural projects, photos and sketches, diary excerpts, personal travelogues, fairy tales, and fables, as well as critical essays on contemporary architecture and society. 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.
