The Siku Quanshu was copied seven times — four complete sets survive
Compiled in the Qianlong era, the Siku Quanshu collects 3,461 works in over 79,000 scrolls, some 800 million characters, copied into seven sets housed in seven pavilions north and south: Wenyuan (渊), Wenyuan (源), Wenjin, Wensu, Wenhui, Wenzong and Wenlan.
Afterward the Wenyuan (源) set at the Old Summer Palace burned with the Anglo-French forces, the Hui and Zong sets fell in the Taiping war, and the Wenlan set was scattered and later re-copied. Today only Wenyuan, Wenjin and Wensu survive complete, plus the restored Wenlan set — the word "complete" was always fragile.
