bet, Murray's suggestion of making xerox copies for your own use and then storing the originals is a good one. Not all plastic is good for storing paper. I suggest you check out the local frameshops, art supply stores, (and local museum if you have to). They can refer you to the many archival storage products on the market. Handle the paper with white cotton gloves, store it in acid free flat boxes with protective covering inside. I have alot of the old sheet music, too, and it has been shuffled around for years in our piano bench.
