Does National Geographic still publish a per-volume index? i.e. 2 per year. If not, what year were the last 2 published? Did a yearly index replace it the following year? Alright, 3 questions.
The society published yearly (1 per year) indexes from 1993-2010. These included all publications (Traveler, Kids etc.)in one index for the year. 2010 was their last index. They do not publish indexes anymore.
I had about a dozen old indices shipped to me as a bonus and was toying with the idea of collecting them. I was just curious as to their numbers.
