Paul Gooding. Historic Newspapers in the Digital Age: 'Search All About It!' London and New York: Routledge, 2017. I was hoping for more of a practical guide to the many methodological issues involving the use of digitised newspapers than this provides; it's much more about the theoretical issues surrounding digitisation and how that connects (or disconnects) with how users actually interact with digitised newspaper archives. Still looks interesting.
Richard F. Hamilton and Holger H. Herwing. War Planning 1914. New York: Cambridge Universty Press, 2010. A useful survey of the evolution of how the major European powers planned to fight in 1914 -- and 1915, since Italy is included, though Turkey is not.
G. Gibbard Jackson. The Splendid Book of the Army and the Air Force. London: Sampson Low, Marston, [1932?]. A very splendid book aimed at splendid children to tell them of the splendid work done by the Army and the Air Force -- in the latter case including Hendon and air control, in a way which Baden-Powell could have found no fault. A gift: thanks, Richard!
Michael John Law. The Experience of Suburban Modernity: How Private Transport Changed Interwar London. Manchester: Manchester University Press, 2014. Cars, bicycles, motorcycles, yes, yes. But there's also a whole chapter on 'Suburban airmindedness', including (but not limited to) the experience of air displays such as (but not only) Hendon. Excellent.
Susan Pedersen. The Guardians: The League of Nations and the Crisis of Empire. Oxford: Oxford University Press, 2015. A very well-received study of the mandate system, its limitations, its failures and its critics. Of most interest to me, though, is the chapter on the response to the French bombing of Damascus in its Syrian mandate in 1926, a subject of which I am quite ignorant.
