Thus thoughtfully to lay the foundation of the reading habit is a task beyond praise; upon a basis so sound it falls to our lot to rear, if we can, a worthy and durable superstructure. It is time that we passed from books for boys and girls to books for the youth, the man and the woman. And how amid the volume and variety of the accumulated literature of the ages shall we proceed? For light and comfort let us go back a little in the history of education, we shall there find a method substantially that of our friend, Mr. Green. Long before there were any free libraries at all, we had in America a small band of readers and learners who enjoyed unfailing pilotage in the sea of literature. These readers and learners were in the colleges, where the teachers from examination and comparison in the study, the class-room and the laboratory were able to say that such an author was the best in his field, that such another had useful chapters, and that a third was unreliable or superseded. While literature has been growing from much to more, this bench of judicature has been so enlarged as to keep steadily abreast of it. At Harvard there are twenty-six sub-libraries of astronomy, zoology, political economy, and so on; at hand are the teachers who can tell how the books may be used with most profit. Of the best critics of books in America the larger part are to be found at Harvard, at its sister universities and colleges, at the technological institutes and art schools of our great cities. We see their signed reviews in such periodicals as the _Political Science Quarterly_ and the _Physical Review_; or unsigned in journals of the stamp of the _Nation_. Fortunately, we can call upon reinforcements of this vanguard of criticism. It would be difficult to name a branch of learning, an art, a science, an exploration, from folk-lore to forestry, from psychical research to geological surveys, whose votaries are not to-day banded to promote the cause they have at heart. These organizations include not only the foremost teachers in the Union, but also their peers, outside the teaching profession, of equal authority in bringing literature to the balances. And the point for us is that these societies, through their publications and discussions, enable these laymen to be known for what they are. Because the American Historical Association is thus comprehensive, its membership has opened the door for an initial task of appraisal, important in itself and significant for the future.
