Sitting at the pinnacle of global moving image preservation, the Library of Congress (LC) Packard Campus for Audio-Visual Conservation serves as more than a national repository; it is the 'Noah's Ark' for cinematic history.

• Scale of Data: The LC holds over 4 million items, ranging from Thomas Edison’s late 19th-century experiments to contemporary 4K digital masters.
• Striking Contrast: The LC's collection dwarfs typical national archives by a factor of 5 to 10. If all the film reels in their care were spliced together, the resulting strip would stretch between the Earth and the Moon multiple times.
• Technical Stakes: As of 2026, the LC is engaged in a high-stakes race against entropy. They are digitizing fragile nitrate films at an unprecedented pace, acknowledging that for many original works, every passing year causes irreversible physical degradation—literally 'evaporating' history.
