Never permit a book to be turned down on its face to keep the place. This easily besetting habit weakens the book, and frequently soils its leaves by contact with a dusty table. For the same reason, one volume should not be placed within the leaves of another to keep the place where a book-mark of paper, so easily supplied, should always be used. Books should not be turned down on the fore-edges or fronts on the library tables, as practiced in most book-stores, in order to better display the stock. The same habit prevails in many libraries, from careless inattention. When necessary, in order to better read the titles, they should never be left long in such position. This treatment weakens the back infallibly, and if long continued breaks it. Librarians, of all persons in the world, should learn, and should lead others to learn, never to treat a book with indignity, and how truly the life of a book depends upon proper treatment, as well as that of an animated being. These things, and others of my suggestions, may seem trifles to some; but to those who consider how much success in life depends upon attention to what are called trifles--nay, how much both human taste and human happiness are promoted by care regarding trifles, they will not appear unimportant. The existence of schools to teach library science, and of manuals devoted to similar laudable aims, is an auspicious omen of the new reign of refined taste in those nobler arts of life which connect themselves with literature, and are to be hailed as authentic evidences of the onward progress of civilization. CHAPTER 6. THE RESTORATION AND RECLAMATION OF BOOKS. We are now to consider carefully the restoration and the reclamation of the books of a library, whether public or private. Nothing can be more important than the means of restoring or reclaiming library books that are lost or injured, since every such restoration will save the funds of the library or collector from replacing them with fresh or newly bought copies, and will enable it to furnish its stores with as many new books as the money thus saved represents. The cardinal thing to be kept always in view is a wise economy of means. An every-day prudence is the price of successful administration. A management which permits any of the enemies of books to destroy or damage them, thereby wasting the substance of the library without repair, is a fatally defective management, which should be changed as soon as possible.
