Is the free public library an institution that will be benefited by the collection, tabulation and discussion of the results of its work, so far as they can be numerically expressed? What are the objects of such collection in the instances above enumerated? In the first place, they are to satisfy mere curiosity. If such curiosity is trivial, the collection of statistics is evidently useless, and I am afraid that more than a little of it, public and private, falls under this head. But curiosity, even when it goes no further, may be perfectly legitimate. Especially is this so about one’s own affairs. When a man is attempting anything he is naturally curious to know whether he has succeeded or not; and to find out, if possible, precisely how far he has gone in the desired direction. He may have property enough to support him beyond all doubt, but it is quite right that he should want to keep a list of his stocks and bonds and to know whether they have risen or fallen in value during the year. Still further, curiosity about other people’s affairs may be legitimate, as, for instance, when one is responsible for their proper conduct in greater or less degree. In the same way the trustees of a free public library, representing the public at large, by whom the library is supported and carried on, have a right to know all possible particulars regarding the way in which their librarian has carried on his work and the results he has reached in it, and the municipality in turn should require of the trustees a strict account of the funds that they have administered. All this information, as far as it can be stated numerically, constitutes a mass of statistics, and this one reason amply justifies its collection and would justify a much larger number of tables than is usually given in a library report, provided only that the information is to the point and is or should be in public demand. But we cannot stop here. A free library, it is true, is not a money-making concern, but it certainly should be run on business principles. The public puts into it a large sum of money and has a right to expect certain returns, which are none the less definite that they cannot themselves be represented in dollars and cents. The library statistic books are therefore, in a way, the records of the business; they show whether it is being conducted conservatively or wastefully, at a profit or at a loss. And as all these record books are open, they enable us, or should enable us to make instructive comparisons between the methods and results of one institution and those of another.
