There's two things online that I recently heard about, downloadable for free.

One is the conference proceedings of Computers in Archaeology from the 2012 conference: Archaeology in the Digital Era: Papers from the 40th Annual Conference of Computer Applications and Quantitative Methods in Archaeology (CAA)
 and the second thing is Christina Petty's thesis about the warp-weighted loom, both in archaeology and in current practice, available here.
