This is a very incomplete list of the go books I own. They were originally organized by whether or not I had read them, but I didn't like that organization so I decided to scrap it and start again.
Kyu-dan ratings are in KGS rankings, and since I am only a 2k myself, some of the higher ratings are really just guesses.
