Kept More Private Than Their Sex Lives, CEO Libraries Reveal Success.

The New York Times reports that serious leaders who are serious readers build personal libraries dedicated to how to think, not how to compete. And perhaps even more than their sex lives or bank accounts — chief executives keep their libraries private.

Few Nike colleagues, for example, ever saw the personal library of the founder, Phil Knight, a room behind his formal office. To enter, one had to remove one’s shoes and bow: the ceilings were low, the space intimate, the degree of reverence demanded for these volumes on Asian history, art and poetry greater than any the self-effacing Mr. Knight, who is no longer chief executive, demanded for himself.

Michael Moritz, the venture capitalist who built a personal $1.5 billion fortune discovering the likes of Google, YouTube, Yahoo and PayPal, and taking them public says he rarely reads business books, except for Andy Grove’s ‘Swimming Across,’ which has nothing to do with business but describes the emotional foundation of a remarkable man. “I re-read from time to time T. E. Lawrence’s ‘Seven Pillars of Wisdom,’ an exquisite lyric of derring-do, the navigation of strange places and the imaginative ruses of a peculiar character. It has to be the best book ever written about leading people from atop a camel.”

Students of power should take note that C.E.O.’s are starting to collect books on climate change and global warming, not Al Gore’s tomes but books from the 15th century about the weather, Egyptian droughts, even replicas of Sumerian tablets recording extraordinary changes in climate, according to John Windle, the owner of John Windle Antiquarian Booksellers in San Francisco.

Until recently when Steve Jobs of Apple sold his collection, he reportedly had an “inexhaustible interest” in the books of William Blake — the mad visionary 18th-century mystic poet and artist.

Over the years, philanthropist and junk-bond king Michael Milken has collected biographies, plays, novels and papers on Galileo, the renegade who was jailed in his time but redeemed by history.

And poetry speaks to many C.E.O.’s. “I used to tell my senior staff to get me poets as managers,” says Sidney Harman, founder of Harman Industries, a $3 billion producer of sound systems for luxury cars, theaters and airports. Mr. Harman maintains a library in each of his three homes, in Washington, Los Angeles and Aspen, Colo. “Poets are our original systems thinkers,” he said. “They look at our most complex environments and they reduce the complexity to something they begin to understand.”

If there is a C.E.O. canon, its rule is this: “Don’t follow your mentors, follow your mentors’ mentors,” suggests David Leach, CEO of the American Medical Association’s accreditation division. Mr. Leach has stocked his cabin in the woods of North Carolina with the collected works of Aristotle. Read.
