In particular note Ravi Vakil's 500+ page book-in-progress on algebraic geometry, as well as a blog -- he is constantly soliciting and incorporating advice from people who are reading the book. (Remind you of any advice you see often on HN?)
There's no way they're a teacher. None. You cannot do this in the education system. There's a law against it, or something. Maybe they're on the run, a renegade teacher, like the professor-version of Archibald Tuttle.
Fully aware of LaTeX. Also fully aware a lot of book creators use things like LaTeX and Adobe to build their books and form their footnotes and keep their TOC / index / internal page references accurate.
I'm also painfully aware that tons of books, textbooks particularly frequently, don't use the information they built the book with to build the digital version, so it becomes a glorified scan that you can download and read, and nothing more.
Thank you.
