Report of the Committee on leather for bookbinding . t. Librarians stated that leather bindings that aremuch used last better than those that are left un-disturbed on the shelves. VI.— To ascertain how far Faulty Construc-tion is responsible for the want of Durability ofModern Leather Bindings. The investigations of the Sub-Committee servedto show that the bookbinder must share, in nosmall measure, with the leather manufacturer andlibrarian the blame for the premature decay ofleather bindings. 25 REPORT ON // was noticed that— I. Books are often sewn on too few the sewing cord used is usually either toothin in itself, or is rendered so in the joints by theundue thinning of the slips. That binders oftencut off some of the slips instead of lacing them intothe boards. These defects render the attachment of theboards to the book almost entirely dependent onthe strength of the leather. In some recently bound folios that the Sub-Committee was permitted to strip, it was found thatonly three thin cords had been used, and of these. Fig. 1.^Hollow Back. only two were laced into the boards. In numerousother cases where boards had become detached frombooks, a similar cause of weakness was detected. It was observed that the joints of books sewnon tapes that had been properly laced in, or other-wise firmly attached to the boards, had seldombroken. 2. The use of hollow backs, made as is usualfor library work, tends to throw too great a strainon the leather in the joints, and renders the backliable to break away. In nearly every library visited many books wereseen of which the hollow backs were wholly ornearly detached. LEATHER FOR BOOKBINDING Great attention was paid to this point, and itwas found by careful examination that the stiff paperlinings usual in hollow backs, by preventing theleather on the back from bending freely, exercised avery considerable outward thrust on the leather ofthe joints as the book was opened.
