Peter Almond. 90 Years of the Air League: The Story of British Aviation. London: Air League, n.d. . This history of the Air LeagueThe major British aviation advocacy group, founded in 1909 as the Aerial League of the British Empire, then known as the Air League of the British Empire from 1918 until some time in the 1950s. is very slim - only 30 pages in all - and there are no references, but there's still a lot of valuable info in here that can't be found anywhere else (at least until I get to the Air League's archives myself, and/or find a copy of Gibbs-Smith's version, written 40 years earlier). Some nice pictures too. Graciously provided by the Air League itself.
