A person affected by bibliomania; a compulsive book collector driven by an obsessive urge to acquire books.
From bibliomania + -ian (Greek -ianos, forming nouns for persons with a condition or belief). A variant alongside bibliomaniac, emphasizing the person's identity with the condition.
The distinction between a book lover and a bibliomanian is simple: one enjoys reading; the other can't stop buying books they'll never open, driven by a need that even full shelves can't satisfy.
