Extended data

This classification is based on the following principles:

First, under the guidance of Marxism-Leninism and Mao Zedong Thought, and based on dialectical materialism and historical materialism, we should establish an orderly arrangement of categories, starting from scientific concepts and considering their ideological and political contents.

Second, the classification system should conform to scientific principles, take scientific classification as the basis, and adopt a logical system from total to division and from general to concrete. At the same time, we should consider the characteristics of book classification, not only to accommodate ancient and modern books and materials, but also to fully reflect new disciplines and new things.

Thirdly, in the arrangement of categories and the setting of symbols, we should strive to be concise, easy to understand, easy to remember and easy to use to meet the needs of book classification practice. Fourth, take care of the needs of library and information units for the classification of books and materials, and create conditions for the unified classification and coding of books and materials throughout the country.
