Galileo is public domain!

I'm reading "Feynman, Richard P. (1967), The Character of Physical Law, MIT Press" of which I have an old copy in Italian.
He talks about Galileo and in particular about his intuitions about relativity of motion at constant speed.
So I went to look for Galileo's work, since it MUST BE PUBLIC DOMAIN by now :D

Here are some links I found:
- "Discorsi e dimostrazioni matematiche intorno a due nuove scienze (1638)" book in (ancient) italian, from: source

- in English (here)

- and more generally related: Drawing Mechanics
