Had very little time to look at these archives less than 15 minutes so I took pictures of what I could get. There was alot of renovation going on and alot wasn't available. I'm told however I may be able to enter the vault in the fall to see much more.
The above picture is a book by Galileo that was personally owned by Galileo himself in 1632. That is actually Galileo's handwriting in top left corner. He made several notes in this book.
A closer pic of Galileo's notes
a little less blurry
The next few pics are from a biography of Queen Elizabeth written in 1577
The next couple are from a second edition publishing of the works or William Shakespeare published in 1632 only 16 years after his death
