Library Classification

Library classification, a system of arrangement adopted by a library to enable patrons to find its materials quickly and easily. | While cataloging provides information on the physical and topical nature of the book (or other item), classification, through assignment of a call number (consisting of class designation and author representation), locates the item in its library setting, and, ideally, in the realm of knowledge. | Arranging similar things in some order according to some principle unites and controls information from various sources.
