I did a university project about forty years ago on the aeroplane up to 1913 using almost entirely books by Charles Gibbs-Smith. I still have a copy of The Invention of the Aeroplane 1799-1909 somewhere, but borrowed Early Flying Machines 1799-1909 and a couple of others I can’t remember from the library. Also acquired a facsimile Janes 1913 from somewhere.
