the library is only a potential force--energy in storage--the library plus the librarian may and should be dynamic too. We then have in both school and library the book and the teacher, with the difference that in the school the book is only the teacher’s tool, while in the library the librarian exists to care for the book, to place it in his hands who needs it, and to make it effective. But when we have emphasized the educational side of the library’s activity we have by no means exhausted its field. Its recreative function is hardly less important. A very large proportion of the library’s users go to it for recreation or relaxation. They obtain this, of course, in the same way that they obtain education from books, namely, by the acquisition of new ideas or mental images. The recreation comes in from the fact that these ideas temporarily distract the attention from other ideas connected with daily work and worry, and that they ease the brain in the same way that a strained muscle may be eased by gentle exercise. Evidently it is impossible to draw a line between these two classes of a library’s activity. A zoological or a botanical garden is an educational institution, so is an art museum. Yet the large majority of those who go to them do so for amusement, and the educational benefits obtained are incidental. Those benefits, however, are none the less real, and it would evidently be impossible to give separate statistics of those who have made educational and recreative use of the institution. Yet we find people trying to do this very thing in the case of the public library, which case is quite comparable with those stated above. It is assumed, in the first place, that the use of fiction is purely recreative, while that of non-fiction is educational; and, in the second place, that the recreative use of the library is to be condemned or at least discouraged, in comparison with the other. That either of these can be sustained is very doubtful. The attempted subordination of the recreative work of the library to the educational is at best invidious. Each has its place in the scheme of things and comparison in this case is worse than odious, it is misleading. Further, it is positively impossible to draw a line between educational and recreative books. So far as motives go, one may read Gibbon for entertainment and Madame de Stael’s “Corinne” as an Italian guide book. So far as results are concerned, the intelligent reader always acquires new ideas as he reads; and in most cases the very same idea may and does have both an educational and a recreative function. But although we can draw no line, it is quite possible to pick out books on the one side and on the other, and to assert that these are read chiefly for educational purposes and those for recreation. On which side shall the library throw its influence? There are many good librarians who feel that the popular tendency is too strong towards recreation and that the library should
