1974, the international organization for standardization promulgated the chapter of "library classification" in ISO2784- 1974(E), which divided libraries into six categories: national libraries, university libraries, other major non-professional libraries, school libraries, professional libraries and public libraries.

The professional work of the library consists of many interrelated work links. Generally, it includes four parts: document collection, collation, collection and service. Literature collection is the foundation of the whole library work. Document arrangement includes document classification, subject indexing, description and catalogue organization. Literature collection mainly includes the division of stacks, the arrangement of books, the inventory of collections and the protection of documents.
