Many of the rare Chinese books from Japan found in NTU’s library were directly inherited from the Taihoku Imperial University, the colonial predecessor of NTU, among which are the much-prized Momoki and Kubo collections. Because of Nation Taiwan University’s origins and special historical background, its collection of rare Chinese books from Japan have such characteristics as “abundant in both quantity and content,” “not lacking in rare hand-copied manuscripts,” “many books from the collection of persons of distinction,” and “the presence of classical books that are intricately tied to Taiwan.” An investigation of the plethora of these Chinese books from Japan can be used not only as important source material for research on various editions of a certain books, it can also used as a multi-disciplinary research reference. Furthermore, in the study of the history of Sino-Japanese cultural exchange, these books can provide strong evidence worthy of scholars’ attention.
