crl-11914	Roberts, Matt	Oversewing and the Problem of Book Preservation in the Research Library	1967	8	.pdf	application/pdf	4647	253	70	The power-driven press unleashed a flood of books into the market, and, in conjunction with rising labor costs, compelled the binder to seek more and more sophisticated machinery for binding books. The difference in flexibility stems from the fact that raised cord books have solid backs, whereas books sewn by either of the other methods have hollow backs, which, in conjunction with the looser type of sewing, permits more throw-up in the spine, thus allowing the book to open more easily.15 Sewing on double raised cords actually approaches even oversewing in strength, and generally exceeds it in flexibility.	cache/crl-11914.pdf	txt/crl-11914.txt
