Among the financial results that have already attracted the attention of the public and hence engaged the interest of boards of trustees is the attainment of a proper ratio of expenditure for books to the expense of administration. This ratio is generally regarded by the lay critic as abnormally small, but trustees have generally acquiesced in the librarian’s explanation of the causes that seem to him to make it necessarily so. It is undoubtedly the trustee’s duty to call his expert administrator’s attention to this and all other seeming discrepancies in expenditure, and to make sure that they are not carrying the library too far toward technical perfection at the expense of practical efficiency. _Educational results._--It is only right to require that a library should be able to show that it is increasing the educational content of the community, or raising its educational standard, or at least that it is exerting itself to do so, both directly and by co-operation with other agencies, especially with the public schools. A board of trustees is certainly justified in ascertaining by any means in its power whether this is being done, and if not, in asking an explanation of its librarian. Does everyone in the community know where the library is? Is everyone who would be benefited by it making use of it? Is it a help to the schools, and do the teachers recognize this fact? Does the community in general regard it as a place where material for the acquisition of knowledge is stored and discriminatingly given out? These are questions that can be settled not so much by the examination of statistics as by ascertaining the general feeling of the community. It is much easier for a trustee to find this out than it is for a librarian; and trustees, both individually and as a body, should continually bear in mind the value to them of information along this line. Librarians are apt to talk a good deal about the educational function of the library as an adjunct and supplement to the school. It is to their credit that they have made it an educational force not under pressure but voluntarily, as a recognition of the necessities of the situation. But where such necessities have not yet been recognized or where their full import has been slow of realization, the educational side of library work remains undeveloped. Let the board of trustees notify its executive officer that it expects him to look to this feature of his work as thoroughly as to the condition of his building or the economical expenditure of his lighting appropriation, and all such institutions will experience a change of heart.
