Bookland: Difference between revisions

"'''Bookland'''" is the informal name for the [[Unique Country Code]] (UCC) prefix allocated in the 1980s for [[European Article Number]] (EAN) identifiers of published [[book]]s, regardless of country of origin, so that the EAN [[namespace]] can catalogue books by [[International Standard Book Number|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.

* [[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 name=":0">[http://ismn-international.org/download/GuidelinesGeneral.pdf Guidelines for the Implementation of 13-Digit ISMNs]</ref>
