The building fills with many historical documents, including the three famous one. It's exciting to stand closely to them. But the ink in these paper is very faint and hardly readable. By the way the documents still have their importance.
I'm not an American, so I didn't feel much touching with these documents. However, for foreigner, it's worth to be in the building and look at the documents once in a life time.
P.S. The Archive store is full of so many lovely notebook that I could not resist and bought a few of them.
