How can you protect book spines in a bright sunroom library?

Protect book spines in a bright sunroom library by installing UV-blocking window film or using lined drapery to filter harsh sunlight. Facing the library zone away from southern and western exposures where sunlight is strongest minimizes damage. Regularly rotate books to avoid prolonged light exposure on the same sides. Proper UV protection extends book life and keeps colors vibrant, preserving your collection in a light-filled sunroom.
