According to the biography of Cao Xiu, the author of Wenshi Zhuan was Zhang Yin (張隱); according to the biography of Xun Yu, the author was Zhang Heng; according to the biography of Wang Can, the author was Zhang Zhi (張騭). Editors of historical bibliographies have concluded that the author was most probably Zhang Zhi (張騭). However we have no chronologically close proof of authorship, nor indeed any strong indication that there was only a single book named Wenshi Zhuan in circulation, rather than two or three written by different authors surnamed Zhang. See Gao Min pp 13–14.
At its first reference, Pei Songzhi explicitly attributes Yi Bu Qijiu Zhuan to Chen Shou. However, he later attributes both an Yi Bu Qijiu Zhuan and Yi Bu Qijiu Zhi (志) to one Chen Shu (陳術). See Records of the Three Kingdoms, 42.1027, biography of Li Zhuan (李譔). According to the biography of Chen Shou in the Chronicles of Huayang, Chen Shu was a contributor to a Ba–Shu Qijiu Zhuan, which prompted Chen Shou to compile Yi Bu Qijiu Zhuan. It is also attributed to Chen Shou in the Book of Jin. The Book of Sui attributes Yi Bu Qijiu Zhuan to a Chen Changshou (陳長壽). See Gao Min (2007), p 14.
Yizhou Qijiu Zhuan, cited by Pei Songzhi only once, may be identified with Yi Bu Qijiu Zhuan.
