International Standard Identifiers (ISBN/ISSN/ISNI)

Korean Bibliographic Standard Center of National Library of Korea is the national agency of ISBN, ISSN and ISNI in Korea and provides metadata on ISBN, ISSN and ISNI based on its database and assigns domestic numbers on them for management purposes.

ISBN(International Standard Book Number)
  • What is ISBN?
    The International Standard Book Number (ISBN) is a system to enhance efficiency of material information and
    bibliographic distribution by establishing and identifying one title or edition of a title from one specific publisher.
  • Benefits
  • The ISBN is a unique international identifier for monographic publications; assigning a number replaces the handling of long bibliographic descriptive records, thereby saving time and staff costs and reducing copying errors.
  • Correct use of the ISBN allows different product forms and editions of a book, whether printed or digital, to be differentiated clearly, ensuring that customers receive the version that they require.
  • The ISBN facilitates compilation and updating of book-trade directories and bibliographic databases. Information on available books can be found easily.
  • The ISBN is machine-readable in the form of a 13-digit EAN-13 bar code. This is fast and avoids mistakes.
  • Many publishing and supply chain systems are based on ISBN.

ISSN (International Standard Serial Number)
  • What is ISSN?
    The International Standard Serial Number (ISSN) is an 8-digit code used to identify newspapers, journals, magazines and periodicals of all kinds and on all media–print and electronic.
  • Benefits
  • Since an ISSN is an identification number for serials or other continuing resources, an ISSN created for any continuing resources helps to identify it with ease regardless of its publishing nation, publisher, language and contents.
  • The ISSN system is the fastest and most efficient way for libraries to collect, mutually borrow, copy bibliographic information and compile comprehensive lists. For distributors, such as publishers and bookstores it is used to order, sell, return and control inventory and management.
  • ISSN-L
  • The linking ISSN or ISSN-L is a new function of ISSN, which enables collocation or linking among different media versions of a continuing resource (periodical publications), defined in the new International Standard on ISSN in 2007 (ISO 3297: 2007). ISSN-L is not a separate numeral system but designates the first assigned (lowest number) ISSN among different media versions of a continuing resource. Only one ISSN-L will be designated regardless of how many different medium versions of a continuing resource exist.
  • Using ISSN-L enables one to collectively search the entire media of a specific continuing resource. To use ISSN-L, show the acronym of ISSN-L in capitals, followed by a space, then by two groups of 4 digits, separated by a hyphen. i.e. ISSN-L 1225-0333
  • ISSN-L is confirmed on the homepage of the ISSN International Center “ISSN-L Table.” The ISSN Network (ISSN International Center and National Center) has the only right to designate ISSN-L.

ISNI (International Standard Name Identifier)
  • The International Standard Name Identifier (ISNI) is the ISO-certified global standard number for identifying millions of contributors and distributors of creative works such as researchers, inventors, writers, artists, visual creators, performers, producers, publishers, aggregators, and so on.
  • The ISNI system uniquely identifies public identities across multiple fields of creative activity and provides a tool for disambiguating public identities that might otherwise be confused.
  • The ISNI is not intended to provide direct access to comprehensive information about a public identity but can provide links to other systems where such information is held.
  • The Korea ISNI Consortium consists of 14 member institutions including Korea Copyright Commission, Korea Film Council and other relevant institutions that manage and control authority entry information in various industries of academia, music and so on.
