I just received my annual check from the university press publisher of my book--$50! Woohoo! I plan to spend it on something special.
Actually, I never expected to make money off the book, just to make tenure. So I'm good with it. My book has now sold 1,097 copies. That sounds so small (it IS small), but for disciplines such as mine, it's not bad. I went to a talk by an editor specializing in my field, and he said that the average number of books sold in the field was 750.
Now to finish book #2! I just hope someone wants to publish it. I've been working on articles too much lately.
