The term, “Dai Ni-sen Toshokan, the second-line Library,” has been appeared in many library articles to describe the function of prefectural libraries. However, the term bears different meanings in the usages of variolls writers under different situations. Defining the term should be one of the great insistent need of the public librarianship in Japan.
In order to find the variety of usages, the author examines articles on prefectural libraries which were published in the period from 1950 to 1965, seeking an origin of each usage and its exact meaning of the original author.
The term was first used by Takashi Ariyama in 1950, then the Secretary-General of the Japan Library Association, to denote the prefectural library which offered two phases of library services, they are; the direct service to the local users, and indirect service through municipal libraries assuming the prefectural library as a center for library cooperation in the area.
After Ariyama, however, only the latter phase was emphasized by many authors. In 1960's, “the library for libraries” function of American state libraries was introduced, and it soon began to be interpreted that it conveyed the same function with the second-line library concept. In 1963, Chusho Toshi ni okeru Toshokan no Un'ei was published by the JLA, and the book emphasized the “Backstop Function” of prefectural libraries to support municipal libraries. Later, this function was called “Indirect Library Service,” and was also regarded to have the same function with the second-line library concept.
In order to develop public library services in this country, appropriate definition of the second-line library concept should be formulated paying proper consideration to the direct library services to users.
