More than one well authenticated instance exists of an individual beginning life as a newsboy or an elevator-boy, and through his use of a public library finding his intellectual powers unfolding until he has entered one of the learned professions. The relation of the library system to the school system opens an almost boundless field of thought, and it is a fact of deep significance that the profound principle involved in it, after having engaged the attention of English and American libraries for years, has been recognized in the educational steps recently taken by the government of Japan, where the two systems are placed on a plane of equality. In the experience of one of the American libraries already referred to, almost the chief hope of the library for the future is placed upon "a class of readers," every year largely increasing in numbers, who comprise the "graduates from the various institutions of learning" in the city, and whose "lines of study and reading" "may be characterized as a carrying forward of those impulses in the direction of right reading which were received in school and college." The library has a no less direct relation to the needs and ambitions of those who have received the invaluable training of "the practical duties of the world," to use Mr. O'Brien's phrase, and it responds with equal readiness to these. There is concentrated in the contemptuous phrase, "book-learning," a popular judgment of condemnation which is for the most part just, on the spurious variety of knowledge which knows the expression of certain principles in books, but knows nothing of their practical embodiment in the life and work of this world. We are glad to observe that Mr. O'Brien's antipathy to this pseudo-knowledge is almost as profound as our own, but his expression of it seems singularly out of place in a philippic against public libraries; for one will seek far before finding an institution more perfectly suited to be a corrective of such a tendency than the modern public library. Does any one claim that the public school system sometimes has an unfortunate tendency to repress individuality and turn out a set of pupils of uniform mould? If so, the public library supplies a means of supplementing and complementing this uniformity by its infinite variety and universality, and it is continually doing this, indeed. Does any one regret that the school system at its best reaches but a fraction of the population and that fraction for but a few short years of their life, and that in too many instances there is a tendency on the part of even these few, educated in the schools, to conceive of their education as "finished," and allow the fabric to become hopelessly ravelled? If so, the public library stands to these members of the community in an almost ideal relation, not only fulfilling very perfectly Mr. Carlyle's characterization of a "collection of books" as "the people's university," but in the peculiarly wide range shown in the demands made upon it, almost as properly rendering it the people's workshop, or laboratory.
