I know my dad has quite the collection of old game programs and magazines. What he uses are plastic sheets that would fit a three-ring binder and then stores them in a small, two level filing cabinet. Not sure how much room you have or if the magazines would fit in there (or if you even want to lock them away at all; I can certainly appreciate displaying them, as they are meant to be enjoyed), but that's the only example I've ever seen.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
