La neuvième porte

The Don Quixote that Corso buys at the beginning of the film is the very famous Joaquin Ibarra edition, published in 1780, which is generally considered as the best, and most beautiful one. He also mentions the Hypnerotomachia Poliphili (Venice, 1499) printed by Francesco Colonna, dubbed "the most beautiful book ever printed". These amazing illustrations can be viewed on the internet.

Real collectors and dealers wouldn't handle books worth $1,000,000 without gloves, and they surely wouldn't smoke or drink wine directly over them. Also, a book that old (not to mention the XVIII century Don Quixote volumes he takes at the beginning) would not resist the way Corso keeps chucking it in his bag or the fact everybody seems to be handling around. Furthermore, no dealer in his right mind would try to photocopy a four centuries old book by placing it in a commercial machine face down and pressing it as depicted in the movie: such actions would inflict severe damage to the printing and binding, drastically affecting its worth. Regardless those characters who see the book as a tool rather than a priceless collectible, Corso and the brothers Ceniza are experts in the matter, and would never treat such rare and priceless books that way.

The opening credits are displayed as if they were hidden in a bookshelf, deeper and deeper into the nine gates of the title.
