I have some old gems that are starting to get damaged by exposure to sunlight, heavy use, etc. I've always stored them in a portable bookcase near or in the kitchen, and the glued bindings are coming loose and the tops of the sewn bindings are tearing, where I pull them with my fingertip. I'm hoping paper covers will help save them so I can pass on the best ones.
I'm thinking of covering them (like we used to do with our high school textbooks) to protect them from further damage.
Do you cover/protect your cookbooks? How and Why, please.
