ISBD stands for International Standard Bibliographic Description. It’s an international standard used to create bibliographic records for library materials. The ISBD provides guidelines for the description of different types of materials, including books, serials, cartographic materials, sound recordings, and other types of materials. The ISBD is used to create uniform and consistent bibliographic records for library materials, making it easier for users to find and access the materials they need. It also facilitates the exchange of bibliographic data between libraries and other organizations. The ISBD is divided into several parts, each addressing a specific type of material and providing specific guidelines for their description.
