Now just to be very clear. I have paid for each and every single one of the 210 books, so I see my actions as making a personal backup that is actually usable. Is all. I can now #selfhost my books, just as I do with my music, TV Series and movies (that I have also all bought, most of it as physical media. Yes, I have quite a big space reserved for physical media like vinyl, CD, DVD in my apartment. Ripped all of it to my NAS Server)
