• ISO 639-1:2002 Codes for the representation of names of languages -- Part 1: Alpha-2 code
• ISO 639-2:1998 Codes for the representation of names of languages -- Part 2: Alpha-3 code

In other words, there are two-letter codes and three-letter codes. Twenty-two of the languages have two three-letter codes. For these languages, the first three-letter code is for bibliographic use (ISO 639-2/B), and the second three-letter code is for terminological use (ISO 639-2/T).
