We have about 500 CDs and a similar number of DVDs. We don't want to get rid of them completely but the storage towers they are currently in are going. I'm happy for the plastic cases to go but want the most space efficient way to keep the discs and the covers/ sleeve notes that will keep them searchable/ organised (so not just sling the whole lot in a big box). Does anyone have any ideas on the best way to keep them safe and tidy without them taking up half my dining room?
