Interesting. There was never anything 'secret' in the English sense about the archives. The Latin, secretus, means separate or set apart. They are unsure about all of the contents anyway since Napoleon messed things up a couple hundred years ago.
It is a reflection of how uneducated we in the west have become. By design of course. I watched a very interesting movie last evening on Amazon. Enemies Within. Dorn and Ayers did not happen into education. It is by design. I will stop now as I am preaching to the choir.
Thank you for that bit of information.
