!!! Overview
[{$pagename}] ([UCC]) has been allocated since the [1980s] within the [European Article Number] ([EAN]) as "country code" 978 (and later 979) 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. This is informally known as "Bookland". The prefix 979 with first digit 0 is used for [International Standard Music Number] ([ISMN]) and the prefix 977 indicates [International Standard Serial Number] ([ISSN]).
