Quote #7
There are also letters on the front cover of each book; those letters neither indicate nor prefigure what the pages inside will say. (3)
Okay, this comes as a bit of a surprise. What's the use of a cover if not to tell you the title of the book? This problem provokes a huge exercise in reason and logic on the part of the librarians.

First: The Library has existed ab aeternitate. That truth, whose immediate corollary is the future eternity of the world, no rational mind can doubt. (4)
Not only does the Library follow strict structural rules, but so does the way in which the librarian makes his argument. In giving us rules (axioms) and using those rules to deduce other truths (corollaries) about the Library, he's taking a very reasoned and logical approach.
Quote #9
Second: There are twenty-five orthographic symbols. That discovery enabled mankind, three hundred years ago, to formulate a general theory of the Library and thereby satisfactorily solve the riddle that no conjecture had been able to divine – the formless and chaotic nature of virtually all books. (5)
The inhabitants of the Library proceed from the strictly regimented order of the books to a general theory of the Library, using the strictly regimented method of logical deduction. Rules, rules, rules... they're everywhere in this story!
