First, from the Times, a lovely and haunting series of before-and-after panoramas from New York City: first with the WTC and then without.

Second, one of my favorite recent children’s books: The Man Who Walked Between the Towers. The book is quiet shading into contemplative, offbeat and even daring in places, and beautifully illustrated. Beware: if you don’t like choking up in front of your kids, make sure you prepare yourself for the conclusion, which reminds me, in its impact, of Art Spiegelman’s iconic New Yorker cover.
