classification

Library classifications use a notational system that represents the order of topics in the classification and allows resources to be stored in that order. Library classification systems group materials based on similarity. A different kind of classification system, called a faceted classification system, is also widely used, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways. there are several classification schemes.
