Conceptual framework

•In the DDC basic classes are organized by disciplines or fields of study
•At the broadest level, the DDC is divided into ten main classes, which together cover the world of knowledge
•Each main class is further divided into ten divisions, and each division into ten sections (not all numbers for the divisions and sections have been used
•The main structure of the DDC is presented in the DDC Summaries.
•The first summary contains the main class
•The second summary contains the hundred divisions
•The third summary contains the thousand sections
•The first and second summaries are provided for browsing purposes, and the headings do not necessarily match the name of the sections found in the schedules.
