the Vatican porn collection

Stumbled across this old (1982) Straight Dope column on the Vatican's alleged 'world's largest porn collection'. Cecil Adams makes short work of this old (pope) urban myth, pointing out that most of the collection - at least that they are willing to admit to - predates the Englightenment (doesn't everything there?). He asks the natural followup - who does own the world's largest porn collection and where is it kept? - and offers some interesting leads. One interesting note from Cecil's column - the microfilm of the Vatican's porn collection is housed in John Ashcroft's home state of Missouri.
