I found an app for my Android phone that is called The Elder Scrolls Books and it has all the books from the various games in it. I am wondering however if this same set is available via PDF? Would love to sit down and read through the various in game books.

I searched "Books of Skyrim" on google and got an iBooks version. They have it in a Kindle Version too. Keep in mind that these are mainly the books in Skyrim and not so much the past games.
