Background of book classification creation:

Book classification is a classification table compiled on the basis of scientific classification, according to certain ideas and views, combined with the contents and characteristics of books and materials. 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 books and materials at all times and at all times, but also to fully embody 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.

Editorial Committee of China Library Classification

The editorial board of China Library Classification is an organization that studies, compiles, revises and manages various editions (including sub-tables) of China Library Classification. It is led and presided over by the National Library, and its members are experts engaged in classification, thesaurus research, teaching and actual cataloging in the National Library, major public libraries in China, university libraries and university information management departments.

The fifth edition of China Library Classification was officially published by National Library Press on August 20 10. This website has compiled five editions of China Library Classification and related knowledge, and the categories and classification numbers of each edition of China Library have been revised. Please navigate directly to the corresponding category and complete the query of the classification number of China Library Classification.

architecture

Regarding the classification of knowledge, Chairman Mao pointed out in the article "Rectifying the Party's Style": "What is knowledge? Since the emergence of class society, there have been only two kinds of knowledge in the world, one is called production struggle and the other is called class struggle. Natural science and social science are the crystallization of these two kinds of knowledge, while philosophy is a summary and summary of knowledge of nature and social knowledge. " This is the theoretical basis for us to determine the basic structure of classification. Accordingly, this classification divides knowledge into three categories: philosophy, social science and natural science.

Marxism-Leninism and Mao Zedong Thought are the theoretical basis guiding our thinking and the first basic category. In addition, considering the characteristics of the library itself, some books with complex contents and no exclusive categories cannot be classified according to the nature of a certain subject, and they are summarized as "comprehensive books" and put at the end as basic categories.

Updating method

In order to meet the needs of document information organization and retrieval development, China Library Classification and its sub-tables are constantly revised and developed.
