Appoint a good man, then, as your administrative expert; give him a free rein, but not in the sense of following him to dictate the whole policy of your library. Decide for yourselves the broad lines of that policy, relying on your own common sense together with his expert advice; require him to follow out those lines to a successful issue, and hold him responsible for the outcome. So doing you shall fulfil, so far as the limited vision of one librarian enables him to see, the whole duty of a trustee. THE DAY’S WORK: SOME CONDITIONS AND SOME IDEALS[5] What is the library for? What are we, who are in charge of it, to do with it? What point are we striving to reach, and how shall we get there? First of all, the library is a collection of books. Books are to be used by reading them. The whole machinery of the library, its buildings, its departments, its regulations, its disciplined staff, are to bring together the reader and the books. Whatever auxiliary work the library may undertake, this must be its first task. Now to what end is this done? A book from the material point of view is so much leather, paper and printer’s ink, but on the intellectual and spiritual side it is a storage battery of ideas. To put a book into a reader’s hand is to complete a mysterious circuit between the writer’s and the reader’s mind. This charging of the mind with ideas is what we call education. To the physiologist it is a mere modification of brain structure; to the economist and the historian it spreads further out; it is a modification of the individual’s action toward the whole world; it is the alteration of the world’s present status and future history. Education cannot be accomplished by books alone; it can even be accomplished wholly without them; but if they are used properly, there is no one agent that can do more for education than these devices for the storage and transmission of ideas. That the library is an educational institution is now generally recognized. It is common to call it an adjunct to the school, or to speak of it as continuing the work of the school. That the school and the library should work hand in hand where it is possible, goes without saying. But I think we may properly object to any phraseology that implies the subordination of the library to the school. The library stores books and makes them available. Part of the school’s work also is to make available the contents of books. The library may continue the work of the school; but so in some cases may the school merely complete the work of the library. Many a student has received his first inspiration and instruction in the library and has been thereby stimulated to enter a regular course of study. It is better to let the library stand on its own merits as an instructional agent. The difference between it and the school, fundamentally, is that the library’s educational energy is chiefly potential while that of the school is, or should be, dynamic. Yet though
