My attention was drawn to the necessity of a more systematic plan of service in the New York Free Circulating Library on assuming charge in 1895. The library had been hampered by insufficiency of funds and had been obliged to supplement assistants of ability and experience with others who had been employed simply because they could be obtained at low salaries. Promotion, where it was distinctly indicated, was for merit, ascertained simply by the librarian’s opinion; and salary increases were made very largely for length of service. An effort was made at the outset to regulate admission to the force and advancement within it. The features of examination and of grades distinguished by letters were borrowed from the Boston Public Library. A department head, who had been giving private instruction, had by the board’s permission placed some of her pupils in the library for practice work. This seemed an excellent opportunity to train future assistants; so the private class was turned into a library training class and the pupils into apprentices, their teacher being retained as such and properly compensated. The library force was divided into three grades, A, B and C; to which a fourth, D was afterwards added. The first two were indicated by the fact that the library consisted of six coordinate branches, each with its librarian-in-charge and her first assistant. All the former were graded as A and the latter as B. Class A thus necessarily became limited in number, depending on the number of branches, and B would have been similarly limited if it had not been made to include also all the high-grade assistants--all capable of assignment at any time to the work of a deputy librarian of a branch. Class C was then a remainder class, including all other members of the library staff. It soon appeared, however, that the line of demarkation between those members of Class B who were first assistant librarians and those who were not was much more distinct than that between B and C. B was accordingly limited to first assistants; the remnant was called C, and the old C became D. The old feeling that seniority should be considered was deferred to by arranging for automatic increases of salary within the grades at specified intervals. Janitors and messengers remained quite outside this arrangement. It was provided that no one should be promoted from grade to grade without the passage of an examination; but that passage simply placed the successful candidate on a list of eligibles, and promotion from this list was made by considering personal fitness, character of work and immediate conditions. Qualifications for the different grades differed, but in quantity and advancement, rather than in quality, all coming under the heads of literature, language, general information and library economy.
