ISO Language Codes (639-1 and 639-2)

Comprehensive language code information, consisting of ISO 639-1, ISO 639-2 and IETF language types. It contains all languages with ISO 639-2 (alpha 3 / three letter) codes, the respective ISO 639-1 codes (if present), as well as the English and French name of each language. There are two versions of the three letter codes: bibliographic and terminologic. Each language has a bibliographic code but only a few languages have terminologic codes. Terminologic codes are chosen to be similar to the corresponding ISO 639-1 two letter codes.
