A Fundamenta Study on Jesuit Books

在华耶稣会士与中国学者合作，用中文撰写和翻译了许多不同领域的著作。这些耶稣会书籍对中日两国的知识分子产生了重大影响，尤其是在科学领域。这项调查已扩大到日本全国100家图书馆。37个图书馆共藏书866册，其中原版202册，再版387册，手抄本266册。科学类图书数量居首位，宗教类图书次之，宗教类图书再版数量远远超过原版和手抄本。这是由于锁国政策，即除了科学作品之外，所有外国书籍都被禁止进口，并严格禁止基督书籍，因此在明治维新后，他们的19世纪再版被引入。

Jesuits in China wrote and translated many works of various fields in Chinese with the collaboration of Chinese scholars. These Jesuit books made substantial influence on Chinese as well as Japanese intellectual people especially in the field of sciences.The main object of this research project is to survey these Jesuit books preserved in Japanese libraries and to make their catalogue. The survey has extended to one hundred libraries all over Japan. It totals 866 books in 37 libraries, made up as follows: 202 books of original edition, 387 books of reprint edition and 266 hand-written copies. Scientific books take the first place in total number, with religious ones next to it. As for books which belong to the catery of religion, reprints overwhelm original edition and manuscripts in number. This is due to the sakoku policy whereby all foreign books except for scientific works were forbidden to import and a strict ban was excecuted on Chrisitian books, thus their 19th-century reprints being introduced after the Meiji Restoration.
