A library classification is a system of coding and organizing documents or library materials (books, serials, audiovisual materials, computer files, maps, manuscripts, realia) according to their subject and allocating a call number to that information resource. Bibliographic classification systems group entities together that are relevant to the same subject, typically arranged in a hierarchical tree structure (like classification systems used in biology). 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 multiple ways.

Famous quotes containing the word library:
“I view askance a book that remains undisturbed for a year. Oughtn’t it to have a ticket of leave? I think I may safely say no book in my library remains unopened a year at a time, except my own works and Tennyson’s.”
—Carolyn Wells (1862–1942)
