Why the Library of Congress Destroys Rare Books

Watch this video on YouTube ↗
How do you protect paper-based historical artifacts without damaging the priceless originals? Adam Savage visits the Preservation Research and Testing Division at the Library of Congress, where division chief Dr. Fenella France and preservation scientist Dr. Andrew Davis explain the fascinating science of accelerated aging, paper chemistry and sacrificial testing. (Also, are you as surprised as Adam was by Machiavelli's "author photo" in the library's copy of The Prince?)
