While the plans therein described work satisfactorily from an inside standpoint, they are defective in one particular--that of complete record. This is most important in case of investigation by competent authority. While direct control of a library service system by an outside body, such as a municipal or other civil service board, is objectionable, there can certainly be no objection to the requirement, by municipal charter or state law, that the library service be organized and operated on the merit system, which requirement presupposes occasional inquiry to ascertain whether, and in what degree and form, this is the case. Now, in the event of such investigation, it will usually be easy to produce the records of examinations, with marked papers, tabulated marks, and the action based thereon. When it comes to personality and efficiency, such records are not easy to get. Even where libraries assign marks in these subjects and combine them with the results of the written tests to obtain a final mark on which promotion is based, there is nothing to show how the marks were obtained, and the investigating authority might not unnaturally conclude that here was an opportunity to nullify the merit system. Evidently all data on which appointment or promotion is based should be matters of record, otherwise a perfectly well-ordered merit system cannot be demonstrated to be such to one who has a right to know; and, of course, in the last analysis, every citizen has this right in the case of a public institution. What appeared to be needed was some regular report on the efficiency of every employee, which should be taken into account in assigning marks or in some other way, in making promotions, made in such permanent form that it could be filed as a record. Such reports are, of course, constantly made orally and acted upon, without any record being preserved. They are occasionally made in recordable form, perhaps most often in the case of apprentices or members of training classes. In some cases derelictions or unfavorable reports alone have been recorded, but a complete report on personality and work made regularly and filed permanently is a thing that has not come under my observation, although, of course, it may exist.
