When handling the books, be gentle, especially with Books 12 and 13 as they have some wear. To maintain them, store them in a dry place away from direct sunlight to prevent further tanning or damage. Avoid getting them wet, and if they get dirty, you can use a soft, dry cloth to gently clean the covers. Check on them regularly to ensure their condition stays as good as possible.
