2022-08-01 05:39:25 How do I prevent the yellowing of pages of a book?

This is always a problem if, like me, you have loads of books lying around.

Once the pages of a book start to yellow, there's no going back.

To prevent pages from becoming discoloured and brittle, here's a few things you can do.

Avoid Sunlight:
Sunlight is one of the biggest causes of book damage. The UV rays in sunlight can fade book covers and turn pages yellow over time, often in less time than you may think.

This is why the page edges will often appear darker than inside. 


Check Indoor Lighting:
Fluorescent lighting is as damaging to paper as sunlight. If you are unable to replace the lighting in the room where your books are stored, you will need to use filtering materials to shield the light.

These materials can also be used on windows to shield the sun's UV rays.
