Librarianship furnishes one of the widest fields for the most eminent attainments. The librarian, more than any other person whatever, is brought into contact with those who are hungering and thirsting after knowledge. He should be able to satisfy those longings, to lead inquirers in the way they should go, and to be to all who seek his assistance a guide, philosopher and friend. Of all the pleasures which a generous mind is capable of enjoying, that of aiding and enlightening others is one of the finest and most delightful. To learn continually for one's self is a noble ambition, but to learn for the sake of communicating to others, is a far nobler one. In fact, the librarian becomes most widely useful by effacing himself, as it were, in seeking to promote the intelligence of the community in which he lives. One of the best librarians in the country said that such were the privileges and opportunities of the profession, that one might well afford to live on bread and water for the sake of being a librarian, provided one had no family to support. There is a new and signally marked advance in recent years, in the public idea of what constitutes a librarian. The old idea of a librarian was that of a guardian or keeper of books--not a diffuser of knowledge, but a mere custodian of it. This idea had its origin in ages when books were few, were printed chiefly in dead languages, and rendered still more dead by being chained to the shelves or tables of the library. The librarian might be a monk, or a professor, or a priest, or a doctor of law, or theology, or medicine, but in any case his function was to guard the books, and not to dispense them. Those who resorted to the library were kept at arm's length, as it were, and the fewer there were who came, the better the grim or studious custodian was pleased. Every inquiry which broke the profound silence of the cloistered library was a kind of rude interruption, and when it was answered, the perfunctory librarian resumed his reading or his studies. The institution appeared to exist, not for the benefit of the people, but for that of the librarian; or for the benefit, besides, of a few sequestered scholars, like himself, and any wide popular use of it would have been viewed as a kind of profanation.
