The Kaogu zhiyi 考古質疑 "Substantial doubts by investigating texts from antiquity" is a biji 筆記 "brush notes" style critical examination of various classical texts. The 6 juan "scrolls" long book was compiled by the Song period 宋 (960-1279) scholar Ye Daqing 葉大慶, courtesy name Ye Rongfu 葉榮甫, who was a famous poet and educational instructor (zhouxue jiaoshou 州學教授) in Jianzhou 建州 (modern Nanping 南平, Fujian).
The Kaogu zhiyi explains Ya Daqing's own view of a large amount of books from ancient times to the early Song period. It touches points not to be found by commentators or other writers, and quotes from earlier commentaries by criticizing them. Ye Daqing saw his book as a kind of supplemen to Cheng Dachang's 程大昌 Kaogubian 考古編, yet without reacher the latter's quality.
The Kaogu zhiyi is to be found in the collectanea Siku quanshu 四庫全書, Wuyingdian juzhenban shu 武英殿聚珍版書, Haishanxianguan congshu 海山仙館叢書, Xiaoyuan congshu 嘯園叢書, Qingfentang congshu 清芬堂叢書 and Fang zhibuzuzhai congshu 仿知不足齋叢書. In 1985 the Shanghai guji chubanshe 上海古籍出版社 published a modern print in a joint edition with the book Yongyou xianping 甕牖閑評, with annotations by Li Weiguo 李偉國. Chen Datong's 陳大同 critical edition Kaogu zhiyi jiaozheng 考古質疑校證 was published in 1989 by the Guangdong gaodeng jiaoyu chubanshe 廣東高等教育出版社.
