While the actual work of getting the right book to the right person may fall chiefly upon the desk assistant, the manner in which this is done emanates from those who decide the policy of the library. If those who are at the head of affairs have forgotten or have never realized that the library exists for the people, and that it is maintained at public expense for that purpose, and because of this lack of knowledge maintain an attitude of arrogance toward the people, the assistants will do the same. It is true that an indifferent and unsympathetic librarian cannot always prevent a capable and efficient assistant from doing her work well, yet the lack of efficiency at the head will often discourage capable assistants and will never better the work of poor ones. In a library of medium size having thirty employees or less it is a comparatively easy matter for the librarian to keep in close touch with the work of the members of the staff and by personal effort maintain a definite standard, while in a large library this duty must of necessity be detailed to others. But whatever the means adopted, every library must have a definite standard of efficiency which bears directly upon the service to the public and although a full knowledge of the technical details of the work of the library are without question necessary, a proper knowledge of the right attitude toward the public is a greater necessity and should receive from the librarian much greater emphasis than the technical side. The characteristic most to be desired in a library employee, in no matter what position, is that of the self-disciplined and well trained servant who understands the rights of others and what they should expect of him in his position, and who attempts to respond to this demand. These characteristics, if they exist, are inherent but may be more fully developed by experience. It may be well to try to outline in a general way what should be expected of the occupants of some of the important positions in a library, for the final outcome of the work will depend upon the librarian's ability to discriminate in the selection of the right persons to fill these positions. For the children's librarian, the first requirement is a knowledge of children and the ability to feel and show sympathy and affection without being sentimental. Many attractions may be introduced into the children's department but the vital things are to know the children and the books. A mistake in the appointment to this position might be more nearly fatal than a mistake in any one of the other departments, for the ability of the children's librarian to discern intelligently those qualities in a book which are right for the child may permanently settle that child's taste in literature. The future well being of the library often depends upon the wise choice of the children's librarian.
