Technically, the relationship is not to Ethnologue codes, but to ISO
639-3 code elements, although I know these are kept in sync by policy.
Ethnologue's site does include vestigial pages for constructed and
historic languages which are actually standardized via Linguist List. I
would argue that the best URL to check for availability is:
http://www.sil.org/iso639-3/documentation.asp?id=xxx
