사고전서
The Qianlong Emperor did not keep his promises to return the books. Any books that did not make it into the "Siku Quanshu" risked becoming part of the "Siku Jinshu" (). The "Siku Jinshu" is a catalogue of over 2,855 books that were rejected and banned during the completion of the "Siku Quanshu". An additional four to five hundred other books were edited and censored. A majority of the books that were banned were written towards the end of the Ming dynasty and contained anti-Manchu sentiment. The "Siku Jinshu" was the Qianlong Emperor's attempt to rid the Qing dynasty of any Ming Loyalists by executing scholars and burned any books that gave direct or implied political attacks against the Manchu.
