Category:ISO 639-2/B

This category lists languages that we happen to identify via their ISO 639-2/B code, even if by coincidence with their ISO 639-3 code. Some languages have two ISO 639-2 codes, one for bibliographic purpose (used by librarians) and another code for technical purpose (preferred for language tagging on the web), however most of them also have a ISO 639-1 code (which should be used instead). Some wikis will still prefer localizations using the newer ISO 639-3 codes only.
