摘要:The Japan Medical Library Association was established in 1927, and its major role is interlibrary loan activities. Arranging the “Union Catalog” of journals and books (holdings list), which is based on the interlibrary loan activities, is one of the basic tasks of the Association. As for the “Union Catalog” of foreign medical books, a total of eight volumes of the “Union Catalogue of Foreign Books in the Libraries of Japanese Medical Schools” was published from 1949 to 1956. This so-called “Union Catalog” has been edited by using a computer from 1977 up to the present. This study reports the history of the “Union Catalog.”
