Kindle. A collection of shorter works. I've enjoyed much of his recent output, but found myself skipping entire pieces here. There are some interesting offcuts from his earlier books: I mostly skimmed the polar exploration stuff, but deeply enjoyed the section on Red Plenty, and to a lesser extent, Unapologetic where we again get further defences of the defence. Boffins summarises the state of British ingenuity, sad only in being incapable of thriving in a time of plenty, and is superior to his book-length treatment Backroom Boys. There's probably some rich cultural anthropology to be mined there, in the "great man of history" mold. Spufford's generous review You could read forever of Robert Irwin's The Arabian Nights: A Companion was probably the pick for me.
Phillip Lopate reviewed it for the New York Times.
