A great book, compiling most of the information on Airship development as of 1917.
There is also an index of every airship used in the Great War, their technical specifications and career/fate.
From the preface:
Available online here:
An International Register of Airships with a Compendium of Airship's Elementary MechanicsThe present volume is the result of a methodical investigation extending over a period of four years in the course of which many hundreds of English, French, Italian, German and Spanish publications and periodicals dealing with the present status as well as with the early history of airships have carefully been consulted and digested. It has thus become possible to gather under the cover of a handy reference-book a large amount of hitherto widely scattered information which, having mostly been published in, foreign languages, was not immediately available to the English speaking public.The information thus gathered is herewith presented in two parts; one being a compendium of the elementary principles underlying the construction and operation of airships, the other constituting an exhaustive, but tersely worded register of the world's airshipping which furnishes, whenever available, complete data for every airship of 500 cubic meters and over, that has been laid down since 1834. Smaller airships are listed only if they embody unusual features.It has been attempted to furnish here the most up-to-date information regarding the gigantic fleet of airships built by Germany since the beginning of the Great War, a feature which may, in a certain measure, repay the reader for the utter lack of data on the Allies' recent airship constructions, which had to be withheld for military reasons. A revised and enlarged edition of D'Orcy's Airship Manual, in which all the airships built during the Great War will be listed and their features duly discussed, will be issued upon the termination of the war.Ladislas d'Orcy, New York City (U.
