Did they consent to having their letters distributed to the entire public? Because this sounds a hell of a lot like prying into personal affairs I have no business with. (No, I did not follow the link.) And before anyone says, "But History!" I think there ought to be a principle operating here akin to the old security example of the difference between a database police can go make a request of, and ubiquitous robots with a data connections that instantly scan every plate in the state and generate a real-time map of where every car is, and who owns it. I don't see anything wrong with (presumably) old letters being stored in an archive somewhere, where those with a interest and motivation can trade some of their time for access. But throwing them out there for everyone on Earth (unless the authors gave their consent for that in advance) does not feel right.
