It may be objected that the great obviously includes the small, and that plans and methods which are good and suitable for the former need but to be reproduced in miniature for the latter. It is true, that, in many departments, the accident of size makes little or no difference in library economy; but in the administration of affairs, in the machinery of running, the director of a municipal library has many and accumulating cares, of which his less burdened rural brother need never feel the weight. Prof. John Fiske, some years ago, at the time when he was assistant librarian of Harvard University, very graphically described a portion of the perplexing duties which fall to the lot of even a university librarian, striving to correct the erroneous but too prevalent notion that such a position is a sinecure. He confined himself to an enumeration and description of the duties which are essentially professional, the multiplicity of details of the ordering, classifying, and cataloging of books. In this direction there is a difference only in amount between the greater and the less. But, in addition to all that Prof. Fiske described, a city librarian must needs oversee as well the thousand and one minutiae which go to make up the sum of a day's work in a circulating library. He must provide for the accurate identification and registration of his borrowers,--no light task when they number tens of thousands of the floating population of a western city, which has more active duties for her police than the following up of delinquent patrons of the public library. He must see to it that the thousands of books which flow over his counters are unerringly charged, and that tardy borrowers are warned of their remissness. These are but a few of the numberless details, many of which are trivial in the extreme, but which all go toward the making up of such a day's work as "none but he that feels it knows." As a machine increases in complications a constantly greater percentage of power is consumed in overcoming friction. This attention to the routine of daily work, which forms much of the severest, because least satisfying, work which a librarian does, may be compared to the friction of machinery; and just in the proportion that the power of his mind and the strength of his body are taxed in this direction, by just so much are they reduced for other duties, the importance of which is specially prominent in the minds not only of the profession, but of the public as well,--an actual knowledge of the books which the library buys, and the exertion of an active personal influence in raising the standard of literature which is drawn from the library. It is precisely in this line of personal influence that there seem to me to be special encouragements to the librarians of small towns, that here, notwithstanding their limited resources, they have peculiar opportunities for attaining an almost ideal standard of excellence in the quality of their work.
