The documentary focus on the technological advancement of printing books and how the way we view and read books has change through out the years. I find it interesting the way people have come enjoy e-books and read things aon a kindle instead of real books.In my opinion i rather read a real book instead of an eletronic copy because for me its hard to focus on reading material that is on a screen rathr than paper. Im sure that there are alot of people like me that will always prefer the feeling of real book instead of electronic one, so im sure the need for actual printed copies of books will never sease to exist.
