This change marks a fundamental departure of the library from its old basis, and one which will affect it greatly, for good and perhaps for ill. The movement toward freedom of administration was really concerned with small matters, and left unaltered the central plan and purpose of the library. But with the assumption of direct educational work for children, for women, for men, the library has entered upon a new epoch in its evolution. It has taken up duties whose performance will demand greatly enlarged resources--of space and of money, of books and of working staff. And what is of even greater importance, the purpose, the point of view, of those who control the library, and the temper of the administration, will change, and ought to change, under the pressure of these new duties. This positive and educational library work falls into two main types--that for children, and that for adults--both men and women. It is still in a tentative condition, in a formative and experimental period. The results are still so few and recent that they do not admit any exact formulation. They permit only general and suggestive statement. Work for children is, in some ways, the easiest educational attempt of the library, since it runs parallel to the work of the schools, and those for whom the work is done are easily reached and easily guided. Its function is, of course, in part to supplement the school. It would be, however, a great misfortune if it were looked upon merely as a supplement to the school, as a means of providing reading which the school ought to buy, but cannot afford. Its purpose is rather to begin in childhood, both for pleasure and for profit, a voluntary association with books which lie wholly outside of the school program. It aims to begin the early formation of the habit of reading as distinguished from study--a habit which will be permanent, instead of ending with the period of formal instruction. It recognizes the fact that school life must soon end, and that when the end comes, the important feature of the child's intellectual condition is not so much the amount he has learned as the temper and habit of his mind toward books. Has he merely learned certain truths from books or are books open to him? It is of fundamental importance to the community that the second alternative be secured. The school libraries and children's librarians are, therefore, not to feel that their duty is to supplement the school. That duty lies on a different, and, in a way, a higher plane, in a more spiritual region. It is their part to make the child a citizen of the world of books, and to naturalize him so thoroughly that he will always remain a citizen. Thus only can he share fully, not only in the high and permanent pleasures that books afford, but also in that great movement of life toward books which marks our time.
