Tiwanaku Books

I finally received the two books on the Tiwanaku that I ordered used through Amazon. They are both really cool; one, "Tiwanaku: Ancestors of the Inca" by Margaret Young-Sánchez is almost like a coffee table book (it's huge) and has big glossy photographs of artifacts, textiles, architectural features and the landscape. The other, "The Tiwanaku" by Alan L. Kolata is a normal-sized book but also has images and maps, including a few groundplans that might be useful. Hopefully after looking through them more closely I'll have a good sense of what I want to do for the final project.
