I own 3000 cd's and counting. Had huge storage headache. Came to realize that while cd was great invention, the jewell case was not so I've had storage head aches for ever. Was at the Cadence Building web site and voila, ran into the "Jewell Case Be Gone Plastic Sleeves" $.15 a piece. What was on approx 30 shelves is now on approx 12. They come in two sizes, one side for tray and cd, other side for booklet, PERFECT, problem solved. Now when I buy something, I just stick it in it's alphabetical spot. Before I would have to rearrange my whole, when ever I accumulated 10 or 15 new cd's.............
