The General Catalogue of Sikuquanshu is the largest official book catalogue in ancient China. Also known as "Sikuquanshu Catalogue Summary", or referred to as "Sikuquanshu Summary". Edited by Yong Rong and Ji Yun in Qing Dynasty. Ji Yun (1724— 1805) was born in xian county, Hebei. Sikuquanshu was compiled in the thirty-sixth year of Qianlong (177 1) and completed in the forty-sixth year (178 1). It is the largest series in the history of China. In the name of "Yoshitani Youwen", subscription is indeed prohibited, resulting in only 346 1 species and 79,309 volumes in the series. The rest of the books that are considered to be of little value and not "illegal" are not included in the Sikuquanshu and listed as "storage items". Other books containing "illegal" content are banned, tampered with and abridged. It can be described as another catastrophe in the history of culture. This book has 200 volumes. There are 10254 volumes, 172860 volumes, 6793 volumes and 9355 1 volume. It basically includes the important ancient books of China before the Qing Dynasty, especially before the Yuan Dynasty. It is divided into four categories: classics, history, philosophers and collections. Under the big category, it is divided into small categories, and under the small categories, it is molecular level. There is a small preface in front of each major category and minor category, followed by comments, which briefly explain the origin, classification reasons and purposes of such works. This book records more than 10,000 kinds of cultural classics including philosophy, history, literature, science and technology before the Qing Dynasty. It is the most widely collected catalogue in China, and contains summaries and comments, which provides an informative bibliography for scholars to study the political, economic and cultural history of feudal society in China. However, it is an official bibliography ordered and supervised by Qianlong, which reflects the views and interests of the Manchu feudal ruling class from the aspects of book selection, content description, abstract and annotation.
