The purpose of this study is on the Shera′s sociological aspect of librarianship. Jesse H. Shera, educator, philosopher, and theoretician, considered that perhaps his most significant contribution to librarianship was not a “thing” but a “concept”. Library was created to meet certain social necessities, and that its development is closely related not only to intellectual history but also to change in the organizational structure and the value system of its supporting culture. It is axiomatic, then, that the library as a social instrumentality. is, as it has always been, conditioned and shaped by the social milieu within which it function. Therefore we are concerned with the need for a new epistemological discipline, a body of new about knowledge itself.
