The SCDD (Dewey Decimal Classification System) is used for classification.
The Dewey Decimal Classification is the most widely used library classification system in the world. It is used in more than 135 countries and has been translated into more than 30 languages. Core Classes are organized by traditional academic disciplines or fields of study. No principle is more basic to the SCDD than the following: the parts of the Classification are arranged by disciplines, not by topics. The SCDD is divided into ten main classes (first summary).
