The aim of this article is to outline the history and importance of the Korean rare books in Coll$grave{e}$ge de France. With this purpose in mind, the historical background and the process of how these books came to Coll$grave{e}$ge de France were studied through cataloguing the list, and then analyzing them by subject, printing type, and timeline. We examined the relationship between the private collections of Maurice Courant(1865-1935) and the Korean rare books held in Coll$grave{e}$ge de France. The Bibliographie Cor$acute{e}$enne written by Maurice Courant is the most important reference book for studying the publication of the late Joseon dynasty and finding the whereabouts of the Korean books in France. Also, we tried to figure out the best way to implement and make use of a bibliographic database, and contribute to the exploration and study of Korean Cultural Heritage scattered outside Korea.
