ISO 639 Code Tables
This page offers a combined view of the language code tables of ISO 639 parts 1, 2, and 3. Select just the elements of the Part 1, 2, or 3 code, or show the set of code elements sorted by name. Viewing by name will enable you to browse for any name associated with a specific identifier, including an inverted form of a name (e.g., the code element id=[aaq] "Eastern Abnaki" will also be found under "Abnaki, Eastern"). The elements may also be ordered by scope of denotation or type of language. The "more" link provides further documentation on what the code element denotes. In the case of a macrolanguage, this includes a listing of its individual member languages.
