Help Authors?
I guess KU is one way to introduce a new author / series to to the masses.
With print books, someone had to front a print run $$. With e-books, that take a TINY portion of a modern HD. (FWIW the majority of titles in my Library would fit on a 1.4M floppy. My Library is stored on a 2T HD that hardly notices it, The main drive is a SSD, for where I want performance)
But the flip side is with a purchase, the Author gets paid, even if I never get around to reading it (The dratted TBR pile
)
