Inside the inner vault

Inside, behind yet another layer of security, is the vault, which is inside this highly secure room with iris-scanner access. This is "probably the most secure room on campus," says our guide. There are 120 safe deposit boxes inside nine fireproof media storage safes within a burglar-proof cage with a special lock. No one can enter the room alone, and multiple keys are needed to open the locks, with only specific people trusted with the access combinations.
