Táng Qiú 湯球 (1804–1881) was a Qīng dynasty scholar and bibliographer who devoted much of his career to reconstructing (jíyì 辑佚) lost early medieval historical texts from fragments preserved in later encyclopedias, commentaries, and quotation collections. His most important project was the Jiǔjiā jiù Jìnshū jíběn 九家舊晉書輯本 (Reconstructed texts of the nine [pre-Tang] histories of the Jin dynasty by nine authors) and associated compilations of fragmentary Wei and Jin historical texts, published in the Guǎngyǎ Shūjú Cóngshū 廣雅書局叢書. The commercial Press (Shāngwù Yìnshūguǎn 商務印書館) republished these texts in the Cóngshū Jíchéng 叢書集成 first series in 1936. Táng Qiú’s reconstructions of the jíyìběn texts at KR4k0332–KR4k0350 — including the Wèi Chūnqiū, the various Jìnjì, the Jìn Yángqiū, the Xù Jìn Yángqiū, the Qí Chūnqiū, and the qǐjūzhù fragments — represent the most systematic effort in the Qīng period to reconstitute the lost pre-Tang Jin historiography.
