Book excerpt: "By far the best book on corporate and institutional governance." —Nicholas Katzenbach, former attorney general of the United States In his new foreword to The Board Book, former Mellon Foundation and Princeton University president William G. Bowen brings his immense experience to bear on the most pressing questions facing boards of directors and trustees today: seeking collaborative relationships and placing a renewed emphasis on sustainable initiatives. The strategies Bowen relates throughout the book foster the collegiality and sense of purpose—more important in today’s turbulent times than ever before—that are integral to any effective board.
