I love books but reading a paper book is a no go nowadays. So what I do if I can't get a book I want in digital format that use one of those paper cutter guillotine like tools to get rid of the book's spine (yeah I know it's sacrilege) or press down the pages with a tool so it's almost flat. Then photo each page with a cheap dslr on a stand, ocr them, and voilá I have my own ebook in whatever format I want. I can make highlights, take notes etc. The process can be accelerated with two dslrs and aligning the pages in a diy wood stand.

Also there are book scanners out there, but don't know the price on these.
