Harvard is not just a university, it's a whole city. It spreads out over the quaintly pretty town of Cambridge, near Boston, Massachusetts, with Harvard Law School at one end, Harvard Business School at the other and the grandest part, Harvard Yard, in the middle, where the undergraduates live and study. I walk into the vast Widener Library ... and am confronted with a Gutenberg Bible. Across the street is the Annenberg Hall, where first-year undergraduate students eat. With its huge stained-glass windows and chandeliers, it is more Hogwarts than anything at Oxford or Cambridge.
