A '''Librarylibrary Classification (LC)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 arranged by many different factors, typically in either a hierarchical tree structure based on the subject or using a [[faceted classification]] system, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways.<ref>{{Cite web |date=March 29, 2023 |title=Library Classification |url=https://www.librarianshipstudies.com/2015/08/library-classification.html |access-date=March 15, 2024 |website=Librarianship Studies & Information Technology}}</ref>
