Bob Gates, according to the Checkpoint Washington blog at WaPo (here), is to become chancellor at Wm & Mary and is planning two books: a memoir and "a treatise on leadership."
Gates is widely respected but please, not another treatise on leadership. I don't read such things (not having any particular reason to) but the mere thought of another one's coming into existence is irksome.
Also there's a piece in the Style section comparing Princeton economists Alan Krueger and Paul Krugman. There are one or two substantive points in there but first you have to wade through stuff about which one plays tennis, which one looks "mildly" like a Hobbit (sic), and so on. (Sorry, no link on this one. I don't get paid enough.)
