The purpose of the Iranian Documentation Centr (Irandoc) was to collect that portion of the world's literature which was pertinent to Iran's research interests, to organize that material, and to promote its use by Iranian researchers. Stated more succinctly, Irandoc's purpose was to obtain ready access to the world's scientific literature in order to improve Iranian research projects. Stated in still another way, Irandoc was (1) building the national science and social science library, (2) providing documentation level services for it, and (3) participating in regional and international information networks. In carrying out these purposes, the Centre collected current book, periodical, document, and report material, organized it, and brought it to the attention of Iranian researchers for use with specific projects. Irandoc's goals included service to the following users: university faculty members, university students, industrial research and development centers, industrial production units, business firms, hospitals, research institutes, government ministries and agencies. In its first three years, Irandoc provided service to these groups plus physicians, engineers, agriculturalists, scientists, chemists, lawyers, educators, economists and others. This paper is a history and description of the establishment and early existence of Irandoc. (LI 004244 through 004251 and LI 004253 through 004267 are related.) (Author/SJ)
