That's true. I have the good fortune to work at a college (Olin College) that recognizes that my work developing textbooks is aligned with the mission of the institution, and can have as much external impact as research. But you are right -- most places give professors zero credit for writing textbooks.

Hey man,

Just wanted to thank you for all the stuff you have given us. I have found your books to be both delightful and enlightening, and the fact you give them away is pretty astounding. I myself buy the printed copies just to support this work, however I know many many people not of means that I point your resources to with great success.

I don't know if you hear it a lot or not enough, but thank you, sincerely. Solid material you got here.

Seconded, I have Green Tea Press bookmarked and I've been meaning to read through The Little Book of Semaphores for a couple months now

We could use a few more schools that think like that!
