Lex Luthor: A Librarian's Superhero

I just re-watched Superman: The Movie (1978) and something new stood out for me. I do not claim to be an expert when it comes to comic books or comic book characters, in fact all I really know about Superman comes from the 1978 film. What stood out is Lex Luther's ability to find information to support his evil plans. He is a librarian's superhero. His office is full of books and he knows how to use them. I guess you could say his super power is collocation.
