“ Check the library over occasionally. It need not be done every year. It is an expensive thing to do, in time, and is not of great value when done; but now and then it must be gone through with. It is not necessary to close the library for this purpose. Take one department at a time and check it by the shelf-list. Make a careful list of all books missing. Check this list by the charging slips at the counter. For those still missing make a general but hasty search through the library. Go over each part of the library in this way. ”
