Much valuable help has been derived from the American list; but a large number of its references, and especially those relating to the World-War itself, have not here been reproduced, while so many additions have been gathered in from other sources among which might be mentioned the published catalogue of the War Office Library; the libraries of the British Museum, the Royal Colonial Institute, and the Patent Office; the Journal of the Royal United Service Institution, the publications of the Royal Engineers' Institute, and official or other publications in Great Britain, France, etc., that the Bibliography here presented may, perhaps, be regarded as practically a new compilation, supplementing the excellent purpose which the list of the American Bureau of Railway Economics will undoubtedly serve.
