This is an unoccupied field, and it would be an eminently proper one for the Trustees’ Section of the American Library Association. We librarians should be very glad to know just what you expect us to accomplish, for on that depends our manner of setting to work. Do you wish us to aim at decreasing the percentage of illiteracy in the community? or the arrests for drunkenness? Are we to strive for an increased circulation? And will an absolute increase be satisfactory, or must it be an increase proportionate to population? Is it definitely demanded of us to decrease our fiction percentage? Shall we, in any given case, devote our attention chiefly to the home use or the reference use of the library? Shall we favor the student or the ordinary citizen? These questions, of course, cannot receive a general answer; they must be decided differently in different cases, but at least we may agree on the type of question that it is admissible to answer at all and on the degree of detail to which it is permissible to go in stating a requirement. For instance, is it admissible for a board to say to its librarian, “The results that we require you to show include the following: A well-ordered collection of books classified according to the Dewey system, bound in half duck and distributed with the aid of the Browne charging system?” I think it will be granted that this would be an attempt to control the details of method in the guise of a statement of desired results. But where shall we draw the line? How specific may be the things that a board may properly require of its expert staff? That is the question whose solution by this Section would be an inestimable benefit to all libraries and librarians. At present there is wide difference of opinion and of practice on this point. Many people would not agree at all with the limitations that have just been laid down; even those who do agree would differ widely over their interpretation.
