The great number and variety of such inquiries as are propounded by readers should not appal one. Nor should one too readily take refuge from a troublesome reader by the plea, however convenient, that the library contains nothing on that subject. While this may unquestionably be true, especially as regards a small public library, it should never be put forward as a certainty, until one has looked. Most inquiring readers are very patient, and being fully sensible how much they owe to the free enjoyment of the library treasures, and to the aid of the superintendent of them, they are willing to wait for information. However busy you may be at the moment, the reader can be asked to wait, or to call at a less busy time, when you will be prepared with a more satisfactory answer than can be given on the spur of the moment. What cannot be done to-day, may often be done to-morrow. Remember always, that readers are entitled to the best and most careful service, for a librarian is not only the keeper, but the interpreter of the intellectual stores of the library. It is a good and a safe rule to let no opportunity of aiding a reader escape. One should be particularly careful to volunteer help to those who are too new or too timid to ask: and it is they who will be most grateful for any assistance. The librarian has only to put himself in their place--(the golden rule for a librarian, as for all the world besides), and to consider how often, in his own searches in libraries, in the continual, never-ending quest of knowledge, he would have been thankful for a hint from some one who knew, or had been over the ground of his search before; and then he will feel the full value to the novice, of such knowledge as he can impart.
