UK libraries buy the books and pay additionally for every lend, as it should be.

"...as it should be."

Hey, don't try to convince me. I spend most of the hundreds of dollars I pay for books every year at used book stores and things like estate sales.

I am literally Satan.

Same here. What publishers give to authors is practically zero, so if you want the author to get any money you're better off sending them a donation directly.
