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 155.95, customs associated with clothing at 391, and fashion design of clothing at 746.92) within the conceptual framework.
[2] The list below presents the ten main classes, hundred divisions, and thousand sections.
