I have a million cookbooks. Right now they're in our kitchen cabbinet on the bottom, and it's such a deep shelf so there's no good way to stack them. If I want a cookbook, I have to sit on the floor and dig through them. We're thinking of buying something to make it easier for me, but we have to have something that has closed doors on it because our dog likes to eat things when we leave him alone in the house, so the traditional bookshelf won't work. Any ideas?
