Since the first edition of Princeton University: The Campus Guide in 1999, the investment of more than two billion dollars of capital in more than forty-eight projects has dramatically altered the face of one of America's most beautiful campuses. Contemporary buildings by Allan Greenberg, Schwartz/Silver, Pei Cobb Freed, Tod Williams Billie Tsien, Hopkins Associates, Gehry Partners, and Rafael Vinoly complement major connective landscapes by Beyer Blinder Belle, Michael Von Valkenburgh Associates, Robert Zion, and others. This edition introduces three new campus walks showcasing this new work and the Princeton University Museum of Art, with a tour of the collection by the director; campus art featuring fortyfive pieces by Alexander Calder, Henry Moore, Richard Serra, and others; and the Natural Sciences Neighborhood, a major university initiative over the past fifteen years. The Guide is also expanded to include tours of other nearby institutions, including the Institute for Advanced Study and the Princeton Theological Seminary. A preface by President Shirley M. Tilghman (2001 2013) and an introduction by university architect Ron McCoy set the stage for the Princeton campus in the twenty-first century."
