Yes I was very annoyed that I couldn't find anything more recent .... this "they publish in a lot of very private, small venues" is another annoyance ..I have the same problem with getting resources on Caral .. Dr. Shady has been publishing consistently on Caral but they are publications with the Lima Museum and are unavailable to me.
