Hi!
Why it is deficient?
I guess the problem is that sometimes ethnologue codes may differ from reality. The further away languages get from the west, the lower is the probability of having people inform ethnologue of the problem, in order to correct the situation. Now maybe there really are a number of variations of the buryaty language, one of which has got govt recognition. The problem is that no ethnologue code was issued, following this event. I suspect that more than just one language may find itself in this situation, in the area of the Russian Federation. It would be nice to set up a systematic verification process and clear up the mess.
Gerard, is there any standard procedure we should follow to report the problem to ethnologue?
