So a couple months ago I rearranged my room and put my bookshelf in front of my window, not even thinking about the damage sunlight could cause to my books. Today I noticed how yellow the pages of some of my books are due to sun damage. This is where I need help, would it be better for me to just move my bookshelf to a different area of my room, or should I start slowly replacing the books that have damage to them. I’m absolutely heartbroken at the state of my books, but I don’t know if replacing the damage books is worth it. Any advice would be greatly appreciated
