Bookbinding and its auxiliary branches
A trade manual on bookbinding by John J. Pleger, issued in Chicago by the Inland Printer Company in 1914 for binders, apprentices, and printing-shop workers. Outline diagrams show book covers, spines, joints, and sewn text blocks keyed with letters, while halftone plates record cast-iron bindery machines with flywheels, gears, and treadles, supplying clean construction schematics and period equipment silhouettes.
