The interested librarian will be on the lookout for any new books that may be of use to teachers and pupils; she will try to keep a balance in the matter of books for the various departments of study, to inform herself on current events and, in short, make herself as useful in all lines of high school work as is possible with the time and means at her disposal. =Assistance for the Librarian.=—As the work of the library grows it will be necessary for the librarian to have assistance of some kind. The arrangement for this will depend largely upon the circumstances in the given school. In many schools student assistants are employed. In some cases boys are hired at a small sum per hour to give their services as pages. In others good students are allowed to volunteer for library work, giving one hour a day to it. They enjoy the work and find their enlarged knowledge of the library very useful. In some schools the librarian is assisted by a member of the teaching staff, who thus becomes familiar with the library and acquires some knowledge of reference work and can assist the pupils in various ways. =Purposes of a Library.=—The purposes of a school library should be not only to provide laboratory material for the pupils’ work in literature and history, to enable the teacher to instruct them in the use of books as sources of information, and to assist the teacher in other ways, but also to instil in the pupils an interest in books as books, to cultivate a taste for reading. Too many high school graduates have no conception of a book, other than fiction, as anything but a task or a text. The high school library should not try to compete with the public library if there is one in the same town. Literature for recreation pure and simple is better supplied by the public library, where it is available for those who are both below and above the high school age. But, on the other hand, if there is nothing to interest the students by its innate appeal, if everything in the school library suggests lessons, many of the students will view it with suspicion, and avoid it, unless sent there by the teachers. =Teaching the Use of the Library.=—Most pupils when they enter the high school are ignorant of the use of the simplest and most common reference books. They do not know the difference between a table of contents and an index, and are so helpless in a library that their teachers hesitate to give them work outside their text-books. Even those who are best informed can be helped to the use of books which will be of the greatest assistance to them in the preparation of their daily lessons, essays, and debates.
