After she has worked in the library as an assistant, she should attend classes in a school for librarians. The library training school, conducted under the authority of the Department of Education for Ontario, has a course of several months, with lectures, instruction, and practice work. Library boards frequently grant leave of absence to librarians and assistants so that they may attend this school. Application for admission should be sent to the Inspector of Public Libraries, Department of Education, Parliament Buildings, Toronto. Library schools in the United States give courses of one and two years in all the branches of librarianship. These schools require for entrance either that the applicant has a standing equal to the second year in a university, with a knowledge of French and German, or a university degree. Any young woman who is a college graduate and has a certificate from one of these library schools is likely to find good employment in a library. The technical training which a library assistant must acquire, either in a library or at a library school, includes the classification of books according to subject, the cataloguing of books, some knowledge of binding and repairing, the arrangement of books on shelves, the use of open shelves, how to serve the public, filing and use of periodicals, how to use reference books of all kinds, preparation of reading courses for clubs, how to make the library useful to boys and girls at school, and practice in the children's library. In a small library, while the work is not greatly divided, one librarian, possibly with an assistant, must carry on all the work of the library. In large libraries, the work is divided into a number of departments, each of which is in charge of a responsible head, who may have several assistants. Over all the work of the library is the head librarian. The administrative side of library work calls for executive and business ability. The best experience for a young worker whose gifts are in this direction is to be obtained in a small library. She may, if she has training, become director of such a library and she will gradually win promotion to a larger library, unless she finds that the work where she is suits her capacity better. The cataloguer labels the books as they come in and prepares cards which will represent the books in the catalogue. A book may be asked for under several different classifications, and the skill of the cataloguer is required to decide how many cards are needed and under what headings the books should be listed.
