China Library Classification (formerly known as China Library Classification) is a representative large-scale comprehensive classification compiled and published after the founding of the People's Republic of China, and it is the most widely used classification system in domestic libraries today, referred to as Chinese Library Classification.

The compilation of China Library Classification began at 197 1 and has been published in five editions. Compared with other classifications in China, China Library Classification came into being late, but it developed rapidly. It not only systematically summarizes the compilation experience of China classification, but also absorbs the compilation theory and technology of foreign classification. According to a certain ideological point of view, based on subject classification, combined with the contents and characteristics of books and materials, a classification table is formed according to categories. The China Library Classification adopts the mixed numbering of Chinese phonetic alphabet and Arabic numerals, with one letter representing a major category, reflecting the alphabetical order of major categories, and the disciplines subdivided under major categories are composed of Arabic numerals. In order to adapt to the development of industrial technology and the classification of this kind of literature, the two-letter classification of industrial technology is adopted.
