What does bibliomaniac mean?
A bibliomaniac is a person consumed by an obsessive passion for collecting books. The term derives from Greek roots meaning 'book' and 'madness', and it entered English in the eighteenth century, when extravagant book collecting among wealthy enthusiasts was sometimes treated as an actual affliction. Unlike a bibliophile, who merely loves books and enjoys reading them, a bibliomaniac is driven by the compulsion to acquire: rarity, condition, provenance, and completeness of a collection matter more than the text itself. The word typically carries a playful or gently satirical connotation in modern usage, describing collectors whose enthusiasm has tipped into extravagance — those who mortgage houses for a first edition or haunt auction rooms for a single illuminated page. It remains a favourite term in the world of antiquarian bookselling, where it captures both the devotion and the folly of extreme book collecting.
nounA person who is obsessively enthusiastic about collecting books, especially rare or fine editions; a book-collecting enthusiast carried to an extreme or compulsive degree.
- A person with an obsessive compulsion to collect books, especially rare, valuable, or finely bound editions.

The word entered English in the 1730s as a diagnosis — doctors genuinely treated book-buying obsession as a form of madness.

Etymology of bibliomaniac
Bibliomaniac combines Greek biblion ('book') with mania ('madness' or 'frenzy'), via the French bibliomane. It appeared in English in the mid-eighteenth century (attested from around 1734), when obsessive book collecting was popularly characterised as a genuine mania. It shares its Greek root with words such as bibliography and bibliophile, and its second element with mania and related terms such as kleptomania.
