Actually, there is an even better reason to use the ISO 639-3 link
instead of the Ethnologue link. ISO 639-3 lists code elements for
language collections that are assigned in 639-5 (some of which are also
in 639-2) but not 639-3. Ethnologue does not include these entries. To
test this, do a search for 'aqa' ("Alacalufan languages"):
http://www.ethnologue.com/show_language.asp?code=aqa (fails)
http://www.sil.org/iso639-3/documentation.asp?id=aqa (succeeds)
Ethnologue continues to be an outstanding resource for detailed
information on the languages it does cover, a set which represents the
vast majority of language subtags in the LSR -- just not for determining
which three-letter combinations are available.
