Counting e-books, but still, this is the first year I've sold 200 books.
That means I've earned between $70 and $1000 this year, over the whole year. Still below taxable range.
I've published about 83 books, so in rough estimate I'm only earning about $1.50 per book per year. But some don't sell at all.
