It is poor economy of labor to change the librarian frequently, so much of his usefulness depends on his familiarity with the books, and that familiarity requires time to gain. If you can find a librarian that does not especially need the benefit of the Bible study, one that loves and understands children, keep him in office as long as may be. But be sure to give him an assistant to aid the children in their selections, or record the books while the librarian is consulting with the children; also to take the librarian's place when he is sick or absent, or possibly to take turns with him in presiding over the library, so that each may recite the lesson half the time.

The books will be gathered up on the entrance of the scholars. A table or a basket or an usher may be placed at the door for this purpose. If the scholars cannot be given access to the books and select them themselves, the librarians will pass quietly around among the classes, leaving the new books at each table; but these books are never to be given to the scholars until just before they leave.

The most effective record, yet a very simple one, may be made by any librarian. Give to each scholar a card bearing his name and his number. On this he writes a list of about ten numbers of the books he prefers. As the librarian places his card in one of these new books, that number is scratched off and the date written opposite. At the same time the librarian writes the scholar's number and the date in his library catalogue after the number of the book taken out, and upon a list of the scholars' numbers writes the number of the book after the number of the scholar. When the book is returned lines are drawn through these records. Thus at any time the librarian can see what books are out, who has them, how long they have had them, what books each scholar has read, and how often each book has been taken out.

As the Sunday-school library should teach punctuality, among other good things, the librarian should strictly require every book to be brought back at the end of the week or fortnight, no matter who the scholar may be, or whether the book is in much or little demand. It may not be best to establish any system of fines, but a postal-card notice should be sent in aggravated cases, and sometimes the teacher should be asked to look up the book. It will spur the scholars to promptness if they know that each instance of tardiness is recorded against their names on the library's records.

The proper care of books is another good thing the library should teach. Any marked blemish in a book should be noted when it is sent out; and when a book is injured by a scholar, the librarian should always speak to him about it, or get the teacher to do this if the child is a stranger to him. A plainly printed slip urging careful handling, forbidding dog's ears, and the like, may well be pasted in each book.

It is sometimes possible and advantageous to open the library at some time during the week, especially on prayer-meeting evenings, when the older folks can select their books, or, for the benefit of the children, on Friday afternoons after school.

Some classes will like to have little libraries of their own, containing Bibles for each scholar, Bible atlas, a Revised Bible, a Bible dictionary, a concordance, etc. Always it is well to arrange for the entire school a special reference library, the contents of which will largely change from quarter to quarter. In it will be placed the general Bible helps and whatever books are of special interest for the quarter's lessons. The scholars may be sent to these reference shelves during the lesson hour. At least one school has a special case, always open, for books of this nature, and places the case in the front of its main schoolroom.

On the whole, it will be seen that this chapter is a plea for a Sunday-school library that is a corporate part of the Sunday-school teaching, that will help the teacher on Sunday, and carry his teaching through the week. Such a library virtually adds scores of the wisest men and women to the teaching force of the school, and multiplies by many hours the pitiful thirty minutes given to the lesson.
