You’re missing the point. And we’re not just talking about books, whatever that might mean. We’re talking about all documents ever made. Every magazine article, every blog and web page, every Word doc, etc. I’m pretty sure that whatever is in the Vatican archives is tiny by comparison. Given the age of the Vatican archives, I can also guarantee that many of those “books” are nothing more than page fragments. Very few will be full codices or long scrolls. Many will date before the printing press when document production was slow and laborious.
