Presidential Liberaries are places where former Presidents park their jumbo jets like at Ronald Reagan's.
They are not places where one should be able to find books.
They are also not places where former Presidents should have a penthouse  like Bill Clinton's. It's safe to assume Clinton will use the space to hold Roman Orgies and sacrifice animals.
When Richard Nixon tried to have his Presidential Liberary built on Dukes campus the University (on religious grounds none the less) had a special message for him.
