'''Bookland''' is athe termtongue-in-cheek usedname to refer tofor the [[Unique Country Code]] (UCC) prefix allocated in the 1980s for [[European Article Number]] (EAN) identifiers of published [[books]], regardless of country of origin, so that the EAN space[[namespace]] can catalogcatalogue books by [[ISBN]] rather than maintaining a redundant parallel numbering system. In other words, Bookland is a fictitious country that exists solely in EAN for the purposes of non-geographically cataloguing books in the otherwise geographically keyed EAN coding system.
 
== History ==
[[ISSN]]s (which identify [[periodical publication]]s) are mapped into the UCC 977.<ref>{{citation |url=http://books.google.co.uk/books?id=jKcpAQAAIAAJ |title=International literary market place |year=1999}}</ref>
 
[[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 refershas tobeen dubbed the fictitious country "Musicland". Like ISBNs, ISMNs have been officially allocated using 13 digits since mid 2008.<ref>[http://ismn-international.org/download/GuidelinesGeneral.pdf Guidelines for the Implementation of 13-Digit ISMNs]</ref>
