What bothers me is the Vatican library. It's too vulnerable to fire. There should be staff taking photos of the pages, and store those copies elsewhere.

Yes, you can quickly photograph an entire book with a phone camera. No, you do not need archivists to do it. No, you do not need a scanner. No, you do not need special lighting.

Don't believe me? Pick a book of yours, open it, and take a photo with your phone.
