If you had a question that nobody could answer, you’d go down to the library, open up a drawer with a bunch of note cards in it, look to see if any of the note cards had a word about a concept you wanted to learn about, hope that the card existed, was in the right place, and listed a book that would actually give you the information you wanted.
You'd ask the librarian about where to find books about stuff and get a 3 hour lecture about the Dewey system
