There are many ways to ascertain the edition of an ancient printed book; one of them is to examine the contents of the ”Bei-Ji” (碑記,colophon). However, the contents of the ”Bei-Ji” sometimes contradict each other and cause incorrect judgement. This paper makes a thorough examination of three old ancient books collected in Tunghai University Library. The colophons of these books, Jing-Ji-Zuan-Gu(經籍纂詁) Chun-qiu Fan-lu(春秋繁露), and Li-ji Ji-shuo(禮記集說) present the case for further examinations. The Jing-ji Zuan-gu, lists several formal titles of the editor Ruan Yuan(阮元) in the Collected-Gems Edition(聚珍版,movable type) while the Chun-qiu Fan-lu and Li-ji Ji-shuo indicate that they were ”Block-Printed Editions of Guo-zi-jian(國子監). This paper is intended to analyze the causes of these discrepancies, and to date the edition as when they were carved and printed.
