Guzhou shiyi 古籀拾遺 and Guzhou yulun 古籀餘論

Guzhou shiyi 古籀拾遺 and Guzhou yulun 古籀餘論 are two books on early bronze inscriptions compiled during the late Qing period 清 (1644-1911) by Sun Yirang 孫詒讓 (1848-1908).

Both texts have a length of 3 juan and are in fact extracts of important inscriptions recorded in earlier catalogues, namely Xue Shanggong's 薛尚功 (fl. 1144) Lidai zhongding yiqi kuanzhi fatie 歷代鐘鼎彝器款識法帖, Ruan Yuan's 阮元 (1764-1849) Jiguzhai zhongding yiqi kuanzhi 積古齋鐘鼎彝器款識, Wu Rongguang's 吳榮光 (1773-1843) Junqingguan jinshi lu 筠清館金石錄 (with 66 inscriptions in total) in case of the Guzhou shiyi, and Wu Shifen's 吳式芬 (1796-1856) Jungulu jinwen 攟古錄金文 (with 105 inscriptions) in case of the Guzhou yulun.

Sun copied the reproductions of the original inscriptions (in large seal script, zhou 籀), the analysis of characters and remarks on the history of the vessels. Yet he also added own studies concering the inscriptions by comparing statements with historical records mentioned by imitating the research methods of Wang Niansun's 王念孫 (1744-1832) Hanli shiyi 漢隸拾遺 concerning Han-period 漢 (206 BCE-220 CE) texts written in chancery script (lishu 隸書).

The name of Sun's book Guzhou shiyi was first Shang-Zhou jinshi shiyi 商周金識拾遺. It includes an appendix called Song Zhenghe liqi wenzi kao 宋政和禮器文字考, in which Sun rectifies errors in the research of Cheng Yaotian 程瑤田 (1725-1814, author of Jiezi xiaoji 解字小紀) and Ruan Yuan. The Shiyi was printed in 1888, but first print of the Yulun only appeared in 1929 (Yenching University 燕京大學). It was reprinted in 1931.
