The librarian or assistant librarian who will instinctively rub out all pencil marks observed in a library book deserves well of his countrymen. It is time well spent.
The writing on book-margins is so common a practice, and so destructive of the comfort and satisfaction which readers of taste should find in their perusal of books, that no legitimate means of arresting it or repairing it should be neglected. In a public library in Massachusetts, a young woman of eighteen who was detected as having marked a library copy of "Middlemarch" with gushing effusions, was required to read the statute prescribing fine and imprisonment for such offenses, with very tearful effect, and undoubtedly with a wholesome and permanent improvement in her relations to books and libraries.
In some libraries, a warning notice is posted up like this: "Readers finding a book injured or defaced, are required to report it at once to the librarian, otherwise they will be held responsible for the damage done." This rule, while its object is highly commendable, may lead in practice to injustice to some readers. So long as the reader uses the book inside of the library walls, he should of course report such defects as meet his eye in reading, whether missing pages, plates, or maps, or serious internal soiling, torn leaves, etc. But in the case of drawing out books for home reading, the rule might embarrass any reader, however well disposed, if too strictly construed. A reader finding any serious defect in a library volume used at home, should simply place a mark or slip in the proper place with the word "damaged," or "defective" written on it. Then, on returning the book to the library, his simple statement of finding it damaged or defective when he came to read it should be accepted by the librarian as exonerating him from blame for any damage. And this gives point to the importance of examining every book, at least by cursory inspection, before it is handed out for use. A volume can be run through quickly by a practiced hand, so as to show in a moment or two any leaves started or torn, or, usually, any other important injury. If any such is found, the volume should under no circumstances be given out, but at once subjected to repair or restoration. This degree of care will not only save the books of the library from rapid deterioration, but will also save the feelings of readers, who might be anxious lest they be unjustly charged with damaging while in their hands.
The treatment of their imperfect books (which tend perpetually to accumulate) is very different in different libraries. Some libraries, where funds are ample enough to enable them to do it, condemn any book that has so much as a sentence torn out, and replace it on the shelves with a new copy. The imperfect volumes are sold for waste paper, or put into some sale of duplicate books, marked as imperfect, with note of the damage upon a slip inserted at the proper place in the book, and also in the catalogue, if sold at auction or in a printed list of duplicates offered by the library. This notice of what imperfection exists is necessary, so that no incautious purchaser may think that he is securing a perfect copy of the work.
Other libraries not blessed with means to pursue this course, do as best they can afford, supplying what is deficient when possible without much cost of time or money, or else continuing the damaged book in use "with all its imperfections on its head."
The loss of a single plate does not destroy the value of the book for readers, however to be regretted as diminishing the satisfaction to be derived from the volume. And one can sometimes pardon the loss of a part of a page in a mutilated book, especially when he is made aware of the fact that the library which welcomes him to the free enjoyment of its treasures cannot well afford to buy another.
It is disheartening to read, in an annual report of a public library of circulation in Massachusetts, that many of its popular books are so soiled and defaced, after a few readings, as to be unfit for further service; that books of poetry are despoiled by the scissors to save trouble of copying verses wanted; that plates are often abstracted, and that many magazines "seem to be taken from the library for no other reason than that private scrap-books may be enriched or restless children amused." The only remedy suggested is to examine each book before again giving it out, and, if returned defaced, to hold the borrower responsible.
The art of cleaning books that are stained or dirty, is a matter not widely known, and in this country there are few experts at it. Some of these keep closely guarded the methods they use to cleanse a book. Comparatively few libraries avail themselves of the practice of washing their soiled volumes, as the process is too expensive for most of them, and so they are accustomed to let the library books remain in use and re-issue them again and again, until they become so filthy as to be quite unfit to be seen—much less handled by any reader.
But there are often valuable or rare works which have sustained interior injury, and which it is desired to restore to a clean condition. The best method is to take the book apart as the first step. When separated into sheets, those leaves which are merely dirty should be placed in a bath composed of about four ounces of chloride of lime, dissolved in a quart of water. They should soak until all stains are removed, and the paper is restored to its proper color. Then the pages should be washed in cold water—running water is preferable—and allowed to soak about six hours. This removes all traces of the lime, which would otherwise tend to rot or injure the book. After this, the sheets are to be "sized," i. e., dipped in a bath of size and water, and laid out to dry. This process gives firmness and consistency to the paper, which would otherwise remain too soft to handle. The sheets should be pressed a few hours between glazed paste-boards, as used in printing offices. A cheap and simple size for this purpose may be made by mixing white gelatine with water, and this may be kept in a bottle, so as to be always conveniently at hand. The art of restoring and rendering fit for handling books and rare early pamphlets by sizing all the leaves is in constant use in Europe. By this means, and by piecing out margins, the most rotten paper, ready to drop apart in turning the leaves, may be restored to use, if not quite to its pristine condition.
Ink-spots or mildew stains may be wholly removed, when freshly made, by applying a solution of oxalic or citric acid, and then washing the leaf with a wet sponge. It is more effectual to follow the bath of oxalic acid by applying a solution of one part hydrochloric acid to six parts of water, after which bathe in cold water, and dry slowly. Or an infusion of hypochlorite of potash in twice its volume of water may be used instead of the preceding.
