(9)Towards the close of each academic year all the books shall be called in for a time for stock-taking in order that the library may be compared with the catalogue, losses may be discovered and replaced and binding and other repairs be carried out. The stock-taking should be done by a member of the teaching staff, not by the librarian himself. During this period no person, except with the special permission of the Principal shall have access to the library.(R. & O, Page 305.)
