Only the Fuzhou-zang 福州蔵, which belongs to the third category of Jiangnan canons, has a catalogue named Datang Zhenyuan xinding mulu 大唐貞元新定目録. The compiler and the date of this catalogue are still unknown, and there has been no research on its content and nature. Additionally, the relationship with previous catalogues is also unknown. This catalogue is not included in other known canons, so it is not clear whether it circulated after the Tang Dynasty. It is not clear whether this catalogue influenced the carving of the canon. However, copies have been kept in collections of ancient manuscripts in Japan, and it was printed in the Korean Koryŏ canon. The Japanese manuscripts faithful reflect the original form of the Zhenyuan Xinding Shijiao Mulu, while in the Korean print version it has been changed. This paper focuses on the Fuzhou edition of the catalogue, clarifies its contents, and explores its historical evolution and influence by comparing it with catalogues dating from the middle of the Tang Dynasty, especially the Zhenyuan xinding Shijiao mulu 貞元新定釈教目録.
