For other uses, see Bookland (disambiguation).Bookland is a term used to refer to the Unique Country Code (UCC) prefix allocated in the 1980s for EAN identifiers of published books, regardless of country of origin, so that the EAN space can catalog books by ISBN rather than maintaining a redundant parallel numbering system.
History
Until January 1, 2007, all ISBNs were allocated as 9-digit numbers followed by a 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.
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. The UCC 979 has now been assigned for the expansion of Bookland, and was first used by publishers in the French language, which can use now the additional prefix "979-10-" in addition to the nearly full "978-2-" prefix (onto which legacy ISBN-10 numbers starting by "2-" have been remapped). Books numbered with prefixes other than 978 will not be mappable to 10-character ISBNs.
The UCC 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 books publishers.
Simlar mappings
ISSNs (which identify periodical publications) are mapped into the UCC 977.
ISMNs (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 is also known as Musicland. Like ISBNs, ISMNs have been officially allocated using 13 digits since mid 2008..
