Comments on the Recent Theses on Library Science

Abstract

Persuing various theories which have been advocated with the development of libraray science, problems are mentioned which must be carefully grappled in the future studies.
Library science has its own working field e.g. libraries, which is the positive proof of effectiveness, productivity, and practicability of the library science. As the bibliographic organization a library has the educational and social function. Shera and Egan say that a library is the intermediary service pattern, but it seems that it is neither bibliographic organization nor an international bibliographical liaison organization but it is the positive pattern, in which it is necessary to find the educational function.
Library science is the positive science and its main object is library phenomenon as the behavior pattern. And it consists of theoretical science, practical science, and historical science as far as they are positive. The relationship between the theoretical and practical science is the relation between inside and outside of a thing, so that the difference between two sciences will be given after the library science has been set up. The main force in studying should be concentrated to the field shown by information theory. And by uniting semiotics and information theory including reference function, we must not only analyse quantitatively the library science but also built it up.
