Class Contents

Class 000 is the most general class. It is used for works not limited to any one specific discipline, e.g., encyclopedias, newspapers, general periodicals. The 000s class is also used for specialized disciplines that deal with knowledge and information, e.g., computer science, library and information science, journalism. Each of the other main classes (100–900) represents a major discipline in its own right or a group of related disciplines.
