Siku Quanshu

The Siku Quanshu (the Complete Library of the Four Branches of Literature) was a large book collection compiled in the Qing Dynasty (1616-1911), covering a time span of over 2,000 years from pre-Qin period to Qianlong Emperor's reign. The compilation was personally supervised by Qianlong Emperor (1711-1799). More than 360 renowned scholars and officials, including the famous scholar Ji Yun, were involved in compiling and editing the works and another 4,200 scholars participated in transcription. The project took 15 years to complete (1773-1787). The collection contains over 3,500 important works, with a total of 79,300 manuscript rolls in 36,000 volumes, and about 800 million characters. It is the largest collection of books in ancient China.

The collection is divided into four parts according to the ancient Chinese book classification convention: Classics, His- tory, Works by Renowned Scholars, and Anthologies. Hence, it is called the Complete Library of the Four Branches of Literature. The Classics branch contains Confucian classics and related works; the History section features history books; classified under Works by Renowned Scholars are works of various schools of thought; and the Anthologies section includes collections of poetry, prose, and other literary works. The covers of the four sections are in green, red, blue, and taupe respectively, following the order of the seasons — spring, summer, autumn and winter — for ease of reference. To better preserve and disseminate these classics, seven extra copies were made and stored in libraries across China. Only four of these copies- those stored in the Wenyuan Ge (in the Palace Museum), the Wenjin Ge (in the Chengde Mountain Resort), the Wensu Ge (in Shenyang Imperial Palace) and the Wenlan Ge (the Imperial Library in Hangzhou) - have survived years of vicissitude.

The Siku Quanshu contains an enormous number of ancient texts, covering philosophy, history, culture and art, politics, society, the economy, military affairs, law, medicine, astronomy, arithmetic, biology, agriculture, and divination. It presents China's ancient culture in a systematic way, as an important window into traditional Chinese culture.
