The development of history
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. At present, China Library Classification has been widely used in all kinds of libraries in China, and the classification number of China Library Classification is recorded in major large-scale bibliographies, retrieval publications, machine-readable databases and Chinese national standard book numbers.
