A recent advertisement of a binder stated that his books were rebound more times than the books of any other binder. This statement is a sad commentary on the serviceability of his books and calls to mind a practice of twenty years ago which is too prevalent even at the present time. At that time it was the recognized custom to bind as cheaply as possible books which circulated rapidly and wore out quickly. Those who favor this custom fail to realize that in the case of books which are constantly used the actual cost of binding does not depend on the initial cost per volume, but on the ratio of cost to circulation. This is a point first brought out by Mr. J. C. Dana in his "Notes on bookbinding for libraries," and one on which it is impossible to lay too much emphasis.
