The keeping of books overtime is a purely library offence, committed against the library and to be punished by the library; and with it may be classed such infractions of the rules as failure to charge or discharge a book, loud talking or misbehavior below the rank of really disorderly conduct, such injury to books as does not constitute wilful mutilation, the giving of a fictitious name at the application desk, etc. For all these strictly library offences the favorite penalties seem to be two in number--the exaction of a fine and exclusion from library privileges--temporary or permanent. The former is more used than the latter, and I venture to think unjustly so. From the sole standpoint of punishment the great advantage of a fine is that it touches people in their most sensitive point--the pocket. But this is a ganglion whose sensitiveness is in inverse proportion to its size; in one case the exaction of a cent means the confiscation of the possessor’s entire fortune; in another the delinquent could part with a hundred dollars without depriving himself of a necessity or a pleasure. Of course this lack of adaptability to the conditions of the person to be punished is not confined to this one method. Imprisonment, for instance, may be the ruin of a life to the hitherto respectable person, while to the tramp it may simply mean a month’s shelter and food. But in the case of a money penalty the lack of adaptability is particularly noticeable, and hence wherever it is exacted a large portion of the public comes to forget that it is a penalty at all. Instead of a punishment exacted in return for the commission of a misdemeanor and intended to discourage the repetition thereof, it is looked upon as payment for the privilege of committing the misdemeanor, and it in fact becomes this very thing. Thus, in states where there is a prohibitory law, and periodical raids are made on saloons with the resulting fines, these fines often become in effect license fees, and are so regarded by both delinquents and authorities. Where a municipality provides that automobiles shall not be speeded in its streets under penalty of a heavy fine, the wealthy owners of motor-carriages too often regard this as permission to speed on payment of a stated amount, and act accordingly. So in the library, the fine for keeping books overtime is widely regarded as a charge for the privilege of keeping the books longer than the formal rules allow. Being so regarded, the fine loses a great part of its punitive effect, and largely becomes in fact what it is popularly thought to be. Thus we have a free public library granting extra privileges to those who can afford to pay for them and withholding the same from those who cannot afford to pay--an extremely objectional state of things.
