Personally, I'd use a paid for OCR for books, no matter which format you are displaying it as, as lots of errors can occur and you do need to be able to edit the final result.. in my experience a lot, depending on how bad the printing is how the book binding affects the scan. Its not a precise art, though a friend actually seems to get better results on his smart phone with knfb reader than I can with Adbbey or any other one I've tried using a scanner.
