My collection is mostly in storage, by which I mean it's in a bunch Rubbermaid bins in a basement. I'm getting ready to put it into loooooooooong-term storage. Maybe a third of it is MISB/MOSC, a third is in opened packages, and a third is loose. Give or take. Any specific suggestions I should know about so's I don't open it up in 2013 and find out it all turned to dust or sumthin'?
