The Qing Dynasty compiled the Siku Quanshu, which would become (and remains) the largest book collection in Chinese history. The Qianlong Emperor ordered the start of this monumental task in 1772. Initially, very few people handed in books voluntarily. The emperor issued a decree that stated the books would be returned and no punishment would be made for books containing negative opinions of the government. As a result, over 4,000-5,000 books were handed in; over 3,826 scribes helped to copy every single word from the collected books by hand. Ultimately, the emperor did not keep his promise to return the books. Over 2,855 books were banned, and 400-500 more were edited or censored. Disloyal scholars were executed and many books were burned.
