Several years ago, I worked with Go Game Guru to make the book Relentless. I worked on making all the scripts that generated the book from SGF files, on the typesetting, and diagram-creation.
One of the things I spent a ton of time on was making a new LaTeX font named Gnos (based on Gooe by Dan Bump) to make high-quality diagrams that could be printed by a professional printer. In the process, I collected together a bunch of existing Go-fonts (Igo, and Gooe) and made it much easier to install these fonts: https://github.com/otrego/go-type1
I wanted to publicize this work since this can be an extremely painful process to figure out LaTeX fonts, and it requires a significant amount of trial and error. Maybe it will inspire folks to make more go books!
