When speaking of the efficiency of the employees in a library, it would seem that the same general rule would hold as in other occupations, but this is scarcely true. The people who are served by an institution maintained at public expense expect a higher grade of service than when served by the employees of some private institution or business. No doubt, this is because a higher grade of honor or integrity is expected in the occupant of the office which is maintained for the public good, at the public expense, than one which is maintained for private gain. Naturally the same general rules regarding adaptability, politeness, industry, and various other attributes should be applied to the occupant of any position but in the case of the public servant only the very highest standards should be tolerated. Aside from the public the librarian's first interest should be in the employees of the library. Again and again the statement has been made to the effect that the "work of getting the right book to the right person falls upon the desk assistant chiefly," but as almost all of the employees of a library are desk assistants at some time during each day, it follows that all of the employees bear almost equal responsibility. It would seem that the selection of books for the library should have first attention, but books are easy of selection compared to employees, and easily disposed of if not found to be useful, while the assistant must be carefully placed in the department for which she is the best fitted. For taking all of the valuable characteristics of all of the assistants into consideration, there are to be found as many grades of value as there are books in the library. To be able to do the subject of "the library assistant" justice, the writer should have a very thorough knowledge of human nature, a knowledge generally possessed by successful teachers and sociological workers, but not often by the librarian. Such knowledge comes from a kind of experience not easily obtained by a librarian. It is more to a librarian's credit to know thoroughly the members of the staff and consequently be just to all than it is to have succeeded with any other one piece of work, because perfect justice toward employees will produce the best work for the library.
