Stewart Brand was one of GBN's five founders, created and ran the GBN Book Club until 1999, and continues his involvement part-time. He is also the cofounder and president of The Long Now Foundation, a nonprofit incubator with the mission of fostering long-term responsibility. Its half-dozen major projects include: building a 10,000 year clock inside a Nevada mountain; maintaining a public website (Longbets.org) for "accountable predictions"; working on tools for digital preservation; assembling all the world’s 4,000 documented languages in one place online; and running a series of public seminars about long-term thinking (www.longnow.org).

Stewart's compelling new article on urbanization, "City Planet," was published in the Spring 2006 issue of strategy+business. His books include: The Clock of the Long Now: Time & Responsibility (2000); How Buildings Learn: What Happens After They’re Built (1994); The Media Lab: Inventing the Future at MIT (1987); and sundry Whole Earth Catalogs (1968–1984, National Book Award 1972).
