(Add ironically missing ISBNs to citations)
== History ==
Until January 1, 2007, all ISBNs were allocated as 9-digit numbers followed by a [[modular arithmetic|modulo]] 11 [[checksum]] character that was either a decimal digit or the letter "X". A Bookland EAN was generated by concatenating the Bookland UCC 978, the 9 digits of the book's ISBN other than its checksum, and the EAN checksum digit.<ref>[{{cite web|url= |title=Anatomy of a 13-digit ISBN]|date=March 16, 2015|first=Bill|last=Pearce|archive-url=|archive-date=May 15, 2020|url-status=live}}</ref><ref>{{citationcite book|url= |title=Elementary number theory with applications |authorfirst=Thomas |last=Koshy|isbn=978-0-12-372487-8|publisher=[[Academic Press]]|edition=2nd|page=265}}</ref>
Since parts of the 10-character ISBN space are nearly full, all books published from 2007 on have been allocated a 13-digit [[ISBN]], which is identical to the Bookland EAN. Most of UCC 979 (formerly "Musicland") has now been assigned for the expansion of Bookland,<ref>{{citationcite book|url= PA29|title=Book Marketing Demystified: Self-Publishing Success |authorfirst=Bruce Trelawny |last=Batchelor|year=2010|publisher=Agio Publishing House|isbn=978-1-897435-02-1|page=29}}</ref> and was first used by publishers in the French language, which can now use the additional prefix "979-10-" in addition to the nearly full "978-2-" prefix (onto which legacy 10-character ISBNs starting with "2-" have been remapped). Books numbered with prefixes other than 978 will not be mappable to 10-character ISBNs.
The [[GS1]] is the global identification standards organization for retail. Every country has an assigned country code which precedes the company code. The "country codes" 978 and 979 are now officially registered for allocation by the [[International ISBN Agency]], which maintains the official international registry of ISBN numbers allocated to book publishers.

* [[ISSN]]s (which identify [[periodical publication]]s) are mapped into the UCC 977.<ref>{{citationcite book|url= |title=International literary market place |year=1999|isbn=0-8352-4035-5}}</ref>{{page needed|date=May 2020}}
* [[ISMN]]s (which identify [[sheet music]]) are mapped into the UCC 979. Since the leading "M" of a legacy 10-digit ISMN number (such as M-345-24680-5) is transcoded as 0, the EAN prefix 979-0 is wholly reserved for sheet music and has been dubbed the fictitious country "Musicland". Like ISBNs, ISMNs have been officially allocated using 13 digits since mid-2008.<ref>[{{cite web |publisher=ISMN International |title=Guidelines for the Implementation of 13-Digit ISMNs |year=2007 |url= Guidelines|archive-url= for|archive-date=Aug the21, Implementation2017 of 13|url-Digit ISMNs]status=dead}}</ref>
