³ On this point, see the reviews of Age of Fracture by Michael O'Brien (Times Literary Supplement, 29 July 2011, 8–9); and Lisa Szefel in the History News Network website, HNN, 24 Feb. 2011; and the follow-up discussion in the blog of the Society for US Intellectual History, 4 March 2011, at http://us-intellectual-history.blogspot.com/2011/03/szefel-on-age-of-fracture.html. These reviews came to my notice after my own was essentially completed.
