1. It is cheaper to rebind a book than it is to discard it and later be obliged to buy a new copy.

2. It is cheaper to discard a book when it seems assured that the book's popularity is over, than to bind it and have it remain for years unused.

(d) If the book is much used, is it a book that the library wishes to circulate? Every library has certain books on its shelves of which those in authority somewhat disapprove, but which are very popular and not poor enough to be done away with altogether. It is sometimes the policy to supply only partially the demand for such books; sometimes to discard them entirely when worn out. The good binding assistant will remember the titles of these books and use good judgment in dealing with them when they come into his hands.

(e) If the book is not much read, is it a standard work? For example, in the case of a work of Anthony Trollope the assistant discovers that it was issued only once during the last year and that it is the only copy in the library. If he does not "know books," he will be led to believe that the book has no value and will cancel it. In a large library an action of this sort would be unwise; in a small library the decision would depend upon the particular title. Most libraries keep a book of this particular class in order to supply the occasional demand for it. There are many books not written by men with the reputation of Anthony Trollope which, nevertheless, have intrinsic worth and have a small circle of admirers. They may not have great merit, but on no account should the library be without them. As examples of books of this kind we may take Mrs. Brush's "Colonel's opera cloak" and Theodore Winthrop's "John Brent."

(f) Can the book be replaced with a good reprint which will wear as long as a new binding and cost less? While there are not many cases in which this can be done, the assistant should watch for them. The most noteworthy reprints which will meet these requirements are the volumes in Everyman's Library. In the original Everyman's edition these were entirely unsuited for library use, but in 1910 they were all put into a strong library binding. In the cloth edition they sell for thirty-five cents a volume and can easily be issued from forty to fifty times before being discarded. This makes the cost for each issue as small as can be obtained by binding higher-priced editions.

The following case, which actually happened, illustrates the point, although the books are not fiction. Grote's "History of Greece," in twelve volumes, was in bad condition; several of the cloth backs were torn and the sewing of all the volumes was loose. It was decided to send the books to be rebound at a cost of $5.40. Before doing so, the list of Everyman's Library was consulted and it was found that the work could be obtained in that form in twelve volumes at a cost of $4.20, a clear saving of $1.20, or over 20 per cent. The work was seldom used, yet it was necessary to have the set on the shelves; the Everyman's edition answered every purpose, and will undoubtedly last as long as the rebound set would have done. Unfortunately, owing to copyright provisions, comparatively few of the books which are constantly wearing out can be obtained in this edition.

(g) Is it an old edition, with poor paper and poor type? A book of this sort should never be rebound but should be discarded and a new copy purchased even if the cost of a new copy be much greater than that of rebinding.

(h) If the book is the only copy in the library and is read not oftener than once in ten years, should it be kept because it is important historically? Good examples of this class of unused books are the works of Charles Brockden Brown. They are not interesting at the present time, but when first published were much read. Every student of American literature should read them, and they should be on the shelves of all except the small libraries. Here again good judgment is called for on the part of the assistant.

(i) Is the book used so seldom that it can be recased or recovered by the library? The process of recasing (described on page 184) can be used in the case of small-sized books which have covers showing little evidence of wear, and which do not receive hard usage. The process of recovering (described on page 185) can be used on leather-bound books which have cracked at the joints. In either case the sewing must be perfectly sound.

(j) Finally, let us suppose that we have asked all the foregoing questions and are still undecided what to do. There will be very few cases of the kind. Perhaps the best solution is to wrap the book in paper, letter it with author, title and call number, and transfer it from the fiction shelves to the regular literature shelves. It may stay there for years unused and yet be at hand when finally called for.
