Sad thing. Abraxus was always one of the best, in fact was probably the most academic of the used book stores in Seattle, although the much smaller "Horizon Books" has some pretty academic titles. It surpassed Magus Books in the U-District in this regard. When I saw it the first time in Queen Anne I thought that that was just a new location and that it hadn't moved as a whole.
Anyways, managed to get some good stuff, including cultural anthropologist Marvin Harris' "Cultural Materialism", about analyzing cultural systems, and "Intelligence Reframed" by Martin Gardner, talking about his theory of multiple intelligences.
