DEWEY DECIMAL CLASSIFICATION - VOL. 2 OF 4 - 2021

Classification provides a system for organizing knowledge. Classification may be used to organize knowledge represented in any form, e.g., books, documents, electronic resources. Notation is the system of symbols used to represent the classes in a classification system. In the Dewey Decimal Classification, the notation is expressed in Arabic numerals. The notation gives both the unique meaning of the class and its relation to other classes. The notation provides a universal language to identify the class and related classes, regardless of the fact that different words or languages may be used to describe the class.
