James Mosley (born 1935) is a retired librarian and historian whose work has specialised in the history of printing and letter design.
This collection greatly expanded with the close of the metal type era, which saw many companies and printing shops selling off their equipment and archives.
[9][10] Particular areas of focus of his career have been, in Britain, William Caslon, Vincent Figgins and Talbot Baines Reed, Eric Gill (with whose brother Evan he worked in the 1950s), and, in Europe, the Romain du Roi.
[29] Mosley helped to acquire for St. Bride a large range of printing materials, at a time when companies were disposing of their hot metal typesetting and foundry type equipment or going out of business altogether.
This included material from Monotype, H. W. Caslon & Company, Figgins and the Chiswick Press, as well as materials from printing shops including the collections of Oxford University Press and the Victoria & Albert Museum, supplementing the personal collections of William Blades and Talbot Baines Reed which the library already owned.
