If you have to use books to research something of consequence, a knowledgeable librarian is useful. It's not like they don't know how to use the internet, in many cases they *are* the internet when they scan in the books they have access to (and which have lapsed copyright). This is especially true for extremely niche subjects, try finding a specific book on Converting. There's about ~10 available online and most cost over $50. At that point people will just go to the library instead, because libraries are free.
