Dewey decimal system number for autobiography
List of Dewey Decimal classes
Codes of a library classification system
The Dewey Decimal Classification (DDC) is structured around ten main classes covering the entire world of knowledge; each main class is further structured into ten hierarchical divisions, each having ten divisions of increasing specificity.[1] As a system of library classification the DDC is "arranged by discipline, not subject", so a topic like clothing is classed based on its disciplinary treatment (psychological influence of clothing at , customs associated with clothing at , and fashion design of clothing at ) within the conceptual framework.[2] The list below presents the ten main classes, hundred divisions, and thousand sections.[3]
