I think people are, on the whole, too precious about old things. In the case of books produced after major commercial printing began, I don't believe it is the paper that imbues the book with historical value.

Indeed, I think there's a high chance that this process increases preservation of the most relevant part of the media - the actual content!

There are tons of old rolls of film slowly rotting away in warehouses that were never digitised. Even for beloved media, the BBC occasionally tracks down an old lost episode of Dr Who.

For now these books are in corpuses of training data, but eventually I trust they will make their way to the rest of us.
