The function of the public library is purely and wholly educational. In this case the term is to be construed in its most comprehensive sense. It does not merely include development of the intellect; it involves all the varied human relations. We owe duties to our Maker, to ourselves, to those who are dependent upon us, to our neighbors, to society, and to the state. In all these delicate and intricate relations we must be taught, and as the world advances, our civilization becomes more complex and our relations more involved, the character and quality of our education becomes the more important. The school and the college have merely laid the foundation. If they have done their full duty they have done little more than set the student on the high road. The sequel rests with himself. The public library puts into his hands books, which contain the combined wisdom and experience of all who have gone before, and wherein are preserved the best thoughts of the best men and women of all time. They who pass judgment upon what shall and what shall not be admitted to the shelves of a public library must bear in mind that, strictly construing the function of the library to be educational, there is yet very wide latitude in respect to the things which people may safely and wisely learn. In this aspect of the case, those who are charged with the management and control of libraries have imposed upon them a very grave responsibility. They are not merely the custodians of the books which the public purse has bought; they are commissioned to guide in the path of highest progress. In this light, the function of the librarian assumes the halo of a holy office. He who discharges it earnestly and faithfully may do much to help forward the enlightenment of his generation. The sum of the whole statement, briefly, is this: There is no limit to the concern of the free state in the education of its citizens. It is as much bound to provide libraries in which the adult may continue his studies as it is to maintain schools in which as a child he may begin them. The day is not distant when this duly will be universally recognized in this country. In most of the states compulsory education laws prevail. In at least one, every town is required by law to establish and maintain a free public library. In this respect, New Hampshire is only leading the way in which others will shortly follow.
