GB/T5795-2006
China Standard Book Number is a component of the International Standard Book Number (ISBN) system. The ISBN system was created in 1970. It is a common identification and coding system for the international publishing industry and book trade. An ISBN uniquely identifies a monographic publication in production, sales and distribution. The ISBV system is designed to provide key data about publications for the cataloging and ordering systems of publishers, distributors, libraries and other institutions. It also collects data for publisher directories and catalogs of upcoming publications. The application of ISBN is also conducive to the management of copyright and the monitoring of sales data in the publishing industry.
