Photozincography of Domesday Book

In the 1860s the first facsimile of Domesday Book was created by the process of photozincography (later termed zinco), and was executed under the directorship of Henry James at the Southampton offices of the Ordnance Survey. == Initial stages == Having developed the photozincographic process, in a meeting arranged between James and William Ewart Gladstone, then Chancellor of the Exchequer, Sir Henry expressed his ability to produce photozincographic copies of ancient documents at "a very trifling cost".
