The Qin jiandu heji 秦簡牘合集 [Corpus of Qin documents written on bamboo and wood] is the result of a long-term teamwork and collaboration project, directed by Professor Chen Wei 陳偉 of Wuhan University. This publication provides a new, updated edition of seven collections of Qin documents, including those from Shuihudi 睡虎地 (Tomb 4 and 11), Longgang 龍崗 (Tomb 6), Haojiaping 郝家坪 (Tomb 50), Zhoujiatai 周家臺 (Tomb 30), Yueshan 嶽山 (Tomb 36), and Fangmatan 放馬灘 (Tomb 1). Although former editions have not become entirely useless for the various reasons evoked in this article, Qin jiandu heji should now be considered the new standard edition for any serious academic research on those materials.
