His recommendations are more contemporary (and not so contemporary) classics rather than 2006 books, and he's grouped them into categories. Like this one:
I once wrote a biography myself (of Bill Buckley) and fancy myself an expert on the medium. Those I recommend are Ronald Steel's Walter Lippmann and the American Century (which I used as my writing model), Roy Monk on Ludwig Wittgenstein, and Robert Skidelsky's three-volume biography of John Maynard Keynes, particularly the first volume. One of my favorites among presidential biographies is Stephen Ambrose's two-volume biography of Dwight Eisenhower, which changed many a liberal's view of the general. I also like Lou Cannon's biography of Ronald Reagan, President Reagan: The Role of a Lifetime, which was unjustly ignored when it first appeared, but which, better any other biography, captures how Reagan governed.Interesting reading.
