Roosevelt's library is probably one of the most extensive in the entire city. Even the public libraries don't have what Roosevelt's library has to offer. If a library's intelligence were measured by the amount of books it had inside of it, Roosevelt would have a genius-level IQ. The library is in a completely different building than the school, and is just as nicely polished and preened. If there's something you need to research, this is probably the place to do it.
