Most of the material I've found has focused on the lives of soldiers and rulers, less so on the normal folk. I understand that contemporary Spanish/Catholic records are the most available, yet unreliable due to their viewpoint. The records of the Inca and other peoples were largely not archaeologically stable or were intentionally destroyed.

As an aside, I'm uncomfortable with the term "pre-Contact", and I am curious to know if there is a more sensitive term among historians.
