I read it just after it came out, but Jared Diamond’s book The World Until Yesterday: What Can We Learn from Traditional Societies? has some good material on this topic as well. His work is more toward topics like restorative justice and judicial topics as well as cultural and social pieces we could regain.
Most of the other work I’m talking about relating to memory methods is less widely known/researched and is closer to the bleeding edge of current anthropology and archaeology. That being said, the research is incredibly compelling.
The Noodlemap is looking pretty cool by the way…
