A self-respecting reader will generally heed such hints, which a moment's reflection will teach him are meant to preserve the library book clean and presentable for his own use, as well as for that of others. But there will always be some rude, boorish people who will persist in their brutal and destructive treatment of books, in the face of whatever warnings. How to deal with such unwelcome persons is an ever-present problem with the librarian. If sustained by the other library authorities, a really effectual remedy is to deny the further use of the library to any offender clearly proven to have subjected library books to damage while in his hands. Some librarians go so far as to post the names of such offenders in the library hall, stating that they are denied the privileges of the library by the authorities, for mutilating books. In any case, great care must be taken to have the clearest proof, before proceeding to fasten the offense upon a particular individual. This involves, where the injury is not committed in the presence of any library officer, so as to be observed, but has been done while the book was drawn out, an examination of each volume before giving it out. If this rule were to be observed as to all, it would entail an expense that few libraries could afford. In a large circulating library in a city, it might require the entire time of two assistants to collate the books before re-issuing them. The circumstances of each library must determine how to deal with this matter. Probably the majority will limit the close examination of books before giving them out, to cases where there is reason to suspect wilful continued soiling, scribbling, or dog's-earing. A few such cases once detected and dealt with will have a most salutary restraining influence upon others, especially if re-enforced by frequent and judicious paragraphs in the local press, setting forth the offense and the remedy. But all in vain will be the endeavor to abate these defacements and consequent waste of the library books, unless it is enforced by a positive law, with penal provisions, to punish offenders who mutilate or deface books that are public property. A good model of such a statute is the following, slightly abridged as to verbiage, from an act of Congress, of which we procured the enactment in the year 1878: "Any person who steals, defaces, injures, mutilates, tears, or destroys any book, pamphlet, work of art, or manuscript, belonging to any public library, or to the United States, in the District of Columbia, shall be fined ten dollars to one hundred dollars, and punished by imprisonment from one to twelve months, for every such offense."
