Library classification
Systems of coding and organizing documents or library materials / From Wikipedia, the free encyclopedia
A library classification is a system used within a library to organize materials, including books, sound and video recordings, electronic materials, etc., both on shelves and in catalogs and indexes. Each item is typically assigned a call number, which identifies the location of the item within the system. Materials can be arrange by many different factors, typically in either a hierarchical tree structure based on the subject or using a faceted classification[1] system, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways.[2]
