An examination of the annual reports of libraries in the United States shows that from four to eight per cent of the total income is spent for binding; the amounts ranging from $2,000 to over $40,000 a year for this one item. It must be admitted that these are large sums and that a knowledge of binding materials and processes is necessary in order to spend this money wisely. In many libraries the appropriation for books includes binding and periodicals. It is evident, therefore, that every dollar saved on binding can be devoted to the purchase of books.
And what librarian does not desire more money for new books?
In spite of the importance of the subject a great deal of ignorance has prevailed in years past, and far too many librarians of the present day fail to realize that here is one place where money can be easily wasted. Possibly one reason for the ignorance about binding is that, except in a minor degree, it does not directly affect the public, for librarians are quick to make changes which will increase the interest of the public in the library. Another reason is that experiments are necessary; and since it takes time to draw conclusions from experiments, definite rules have not been formulated.
In fact, experiments are still being tried. But while in the past they were along the line of making books stronger, the experiments of the present are rather along the line of adapting different methods to different books, according to the paper on which they are printed, or according to the kind of use they will receive. It is reasonably safe to say that present methods of the best library binders make a book as strong as it is possible to make it. Progress no longer lies along the line of strength.
In order to administer a binding department wisely, the librarian or assistant in charge of binding must know materials, processes, and books; and especially must he know how books should be bound to meet the use they are to receive. For example, fiction that is very popular should be bound differently from fiction which must be kept on the shelves, but which is not popular; it is easily apparent that McCutcheon's "Graustark" should be bound differently from Henry James' "Golden bowl." Heavy reference books constantly consulted should be bound differently from reference books used only occasionally, while it may be wise to bind magazines differently from either. A librarian of a reference library will adopt methods differing from those which are used in public libraries. A good working knowledge of materials and processes can be easily obtained. The saving of expense comes in applying them to use.
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. A book which costs 35c. to bind and which circulates 35 times has cost one cent for each time it has been issued after rebinding; while a book which has cost 50c. to bind and has been issued 100 times (a fair average for a 50c. binding) costs one half cent for each time it has been issued. Obviously the 50c. binding is much cheaper. It is probable that the 35c. book must either be rebound at an additional expense of 35c. or else a new copy must be purchased at a cost of $1, while the 50c. binding may carry the book to a point where it can be discarded absolutely. Certainly it should never be rebound again. It is important, therefore, that the librarian who does not know what his binding is costing per issue should keep statistics of circulation for a sufficient length of time to obtain general averages which will be fairly accurate.
While a very strong binding is necessary for fiction and juvenile books in public libraries, it is probable that on many books of a serious character some of the strengthening processes which must be used on fiction and juveniles may be omitted. It should be noted that while this is true of public libraries, the reverse would probably be true in college and reference libraries where a much larger proportion of serious books should be bound as strongly as possible.
There are three general kinds of binding:
(a) Commercial, or edition binding.
