Literally, an eater or a consumer of books. More properly in this case a bibliopole, though certainly the buying habits necessary to the pursuit of selling antiquarian books lend themselves to a ready comparison with an insatiable appetite.
This is also the blog-arm of Garrett Scott, Bookseller.
(I am an antiquarian bookseller specializing in obscure and interesting 19th century Americana, social and religious thought, eccentric authors and subjects, pamphlets and ephemera. I am a member of the A.B.A.A.)
