Xiyinxuan congshu 惜陰軒叢書

Xiyinxuan congshu 惜陰軒叢書 "Collectanea of the Cherishing Time Studio" is a series of collectanea (congshu 叢書) compiled by the Qing period 清 (1644-1911) scholar Li Xiling 李錫齡 (c. 1850). It includes 35 books with a total length of 324 juan. The name of the series is derived from the name of Li' study, where he harboured more than 90,000 volumes of books.

Li Xiling, courtesy name Mengxi 孟熙, hailed from Sanyuan 三原, Shaanxi, and was a minor official in the Grand Secretariat (neige 内閣) during the Daoguang reign-period 道光 (1821-1850). The series includes mainly rare books that are hardly to be found in other libraries or publications. It focuses on explanations of the Confucian Classics, bronze and stone inscriptions, and medical texts. Li Xiling died before the collection was published, so that the editing had to be taken over by his cousin Zhang Shu 張樹. The collection is structured according to the four traditional literary categories, and the texts are arranged in 16 book cases (han 函). It is very important because of the rare texts it includes, but also because it contains some versions that differ from those adopted for the imperial series Siku quanshu 四庫全書.

Some editions of the Xiyinxuan congshu are of lower quality, but it is important that they have survived. It was published in 1846 and was reprinted in 1858 and then in 1896.
