Books are now printed in large sheets from 4 to 64 pages at a time. In many cases paper is drawn from a roll (as it is in the printing of a newspaper), printed on both sides in large sections of 64 pages, and cut and folded as it leaves the press. These sheets, of several pages each, after being printed, are gathered into a complete book, sometimes by a machine, and are then sewn together by a machine. This machine for sewing is a comparatively recent invention. In most cases sewing done on a machine is not as strong as the old-fashioned hand sewing. The sections, or signatures, or folds of the book, as the several sets of several pages each are called, are caught together only by thread; strings or tapes are not used. This sewing is then reinforced by a piece of cloth, usually thin, cheap muslin, or poor super, which is pasted over the back and allowed to extend a little way down each side. But sewing on a machine can be done with strings added and made very strong.

B Section of modern “flexible” sewing round single bands.

C Section of ordinary sewing with sunk bands.

D Section of tape sewing advocated for cheap work in place of C.

Covers for books are now made by machines into which are fed pieces of cardboard and a roll of cloth. The machine cuts the cloth into the proper size, pastes it and folds it over the boards into a cover, leaving a loose place between the two boards to be filled by the body of the book. This cover is then printed in a machine much like a printing press; the gold of the title on the back or sides or both, and the colors or blank impressions, for ornament, all being impressed on it with great rapidity. The completed cover, called a case, is then pasted to the sides of the book. A book thus bound has nothing to hold cover and inside together save a strip of thin muslin, with a strip of paper which goes over it, passing from the back of the book to the inside of the board covers. This strip grows weak after a little use and frequently breaks, or pulls away from the cover, or from the back, or from both. Books printed on cheap paper and folded and sewed and bound by machinery in the manner thus very briefly outlined can be produced and sold at present for 10 cents each, or even less.
