The main object of this paper is an attempt to illustrate the present situation of Teheran University Central Library and its 17 faculty libraries. The main aspects of these libraries which will be discussed are collections, staffing, management, shelving, cataloguing and the library users. The findings of a survey which was conducted by the author in Iran in the summer 1995 form the main basis of the discussions. Some of the problems in these libraries are mentioned and the possible solutions are recommended. The study also examines the role and effect of the Islamic Revolution and de-westernization policy of the present regime on these libraries. A historical background of higher education, foundation of the University of Teheran, librarianship and the whole range of libraries in Iran are discussed briefly.
