I've been downloading archived out-of-print books from a great website for a while.
http://www.archive.org/details/texts
It's a 501(c)3 org. I've downloaded books about cats printed in 1889 to 1907 to use for research purposes.
Today, I found 3 cardiology books (one by the World Health Organization printed in 2004, I think). There are some under "heart," but far too many for me to peruse.
If you have a special interest/hobby, you might find a gold mine at this website.
I store the pdf versions of my books on a flash drive.
