I am once again selling books from my library. I shipped one today, getting $78 for it. Today I listed another 10 math, physics, and statistics books at Amazon.com. My pricing strategy is simple: For any given book my price is clearly the lowest. In a couple cases that still let me set a price in 3 digits. There is also a history book I want to sell, but I am giving colgaffneyis members a chance at it before going to Amazon.

Again there was a quantum mechanics text that, after some thought, decided I could not bear parting with. I wonder if it was the same book as back in 2005.
