The Siku Quanshu, variously translated as the "Complete Library in Four Sections", "Imperial Collection of Four", "Emperor's Four Treasuries", "Complete Library in Four Branches of Literature", or "Complete Library of the Four Treasuries", is the largest collection of books in Chinese history. The complete encyclopedia contains an annotated catalogue of 10,680 titles along with a compendiums of 3,593 titles. The "Siku Quanshu" ended up surpassing the Ming dynasty's 1403 "Yongle Encyclopedia" in size, which was China's largest encyclopedia prior to the creation of the Siku Quanshu.
