First, the editor selected 100 kinds of important books from Song Dynasty to Qing Dynasty, and got more than 6,000 kinds of subheadings. Then, after repeated sorting, they got more than 4,000 kinds of books, which were printed as a kind of books (most of them were printed and a few were photocopied), and each book had a number, which was convenient for shelving management and searching. Later, due to the outbreak of War of Resistance against Japanese Aggression, it was not published as planned, but more than 3,000 kinds were actually published.
The collection scope of the series is very extensive. The original edition is divided into 10 and 540 sub-categories, generally including all the ancient books that need to be preserved for future reference. The books collected are divided into ten categories: general, philosophy, religion, social science, philology, natural science, applied science, art, literature and historical geography. It is both practical and convenient to study our ancient cultural heritage.
