Yayutang cangshu 雅雨堂藏書

Yayutang cangshu 雅雨堂藏書 "Library of the Hall of the Rain of Elegance" is a series of collectanea (congshu 叢書) compiled by the Qing-period 清 (1644-1911) scholar Lu Jianceng 盧見曾 (1690-1768). It includes 13 books with a total length of 138 juan.

Lu Jianceng, courtesy name Baojing 抱經, style Yayu 雅雨, hailed from Dezhou 德州 (modern Dezhou, Shandong), and earned the jinshi degree in 1721. He was salt distribution commissioner (yanyunshi 鹽運使) of Liang-Huai 兩淮 and owned a fortune sufficient to attract scholars and retainers in his mansion. He published a collection of calligraphy models of bronze and stone inscriptions called Jinshi sanli 金石三例. His collected writings are the Chusai ji 出塞集.

For each book in the Yayutang cangshu, Li Jiancheng provided a short preface describing the text. The series is enriched by notes of the scholars Qian Qianyi 錢謙益 (1582-1664), Zhu Yizun 朱彝尊 (1629-1709) and Wang Shizhen 王士禎 (1634-1711). The texts had been selected because they were rare books at that time and at the same time reliable versions of a very high quality. A large part of the books are commentaries and critical notes to ancient writings, like Gao You's 高誘 (d. 212) commentary on the Zhanguoce 戰國策 or Lu Deming's 陸德明 (c. 550-630) phonetic comments to the Yijing 易經.

The Yayutang cangshu was printed in 1756 by the compiler himself. Today, it is a widespread series owned by many libraries.
