As an earlier reviewer said, this library takes effort to get into - in fact, it may be impossible if you don't speak Italian. Which we don't. When we showed up, the security guards just shook their heads at us and waved us away. Luckily for us, there was an Italian fellow outside the door, having a cigarette, and he asked us what we wanted. When we told him we wanted to see the library, he took us back in, spoke to the guards at length, and the next thing we knew, we were being issued guest passes. Thank you to our guardian angel. :) The library really is beautiful, of great interest to researchers and historians, I'm sure. I'm so glad we were able to see it. Good luck to all who try.
