"The book was bound by the forwarder, who sewed the leaves and put them in a cover of leather or velvet; by the finisher, who ornamented the cover with gilding and enamel. The illustration of book binding, published by Amman in his Book of Trades, puts before us many of the implements still in use. The forwarder, with his customary apron of leather, is in the foreground, making use of a plow-knife for trimming the edges of a book. The lying press, which rests obliquely against the block before him, contains a book that has received the operation of backing-up from a queer shaped hammer lying upon the floor. The workman at the end of the room is sewing together the sections of a book, for sewing was properly regarded as a man's work, and a scientific operation altogether beyond the capacity of the raw seamstress. The work of the finisher is not represented, but the brushes, the burnishers, the sprinklers and the wheel-shaped gilding tools hanging against the wall leave us no doubt as to their use. There is an air of antiquity about everything connected with this bookbindery which suggests the thought that its tools and usages are much older than those of printing. Chevillier says that seventeen professional bookbinders found regular employment in making up books for the University of Paris, as early as 1292. Wherever books were produced in quantities, bookbinding was set apart as a business distinct from that of copying. "The poor students who copied books for their own use were also obliged to bind them, which they did in a simple but efficient manner by sewing together the folded sheets, attaching them to narrow parchment bands, the ends of which were made to pass through a cover of stout parchment at the joint near the back. The ends of the bands were then pasted down under the stiffening sheet of the cover, and the book was pressed. Sometimes the cover was made flexible by the omission of the stiffening sheet; sometimes the edges of the leaves were protected by flexible and overhanging flaps which were made to project over the covers; or by the insertion in the covers of stout leather strings with which the two covers were tied together. Ornamentation was entirely neglected, for a book of this character was made for use and not for show. These methods of binding were mostly applied to small books intended for the pocket; the workmanship was rough, but the binding was strong and serviceable."
