Here's a simple project that will help keep all those discs organized - inexpensive and easy to create.
Gather a few simple materials: Scrap board, old CD or DVD for placement, plastic hangers, drill with large bits (fitting hangers), pruning sheers (could use hacksaw blade or bread knife), pen or pencil, drywall screws.
Step 1: Mark Board
Step 2: Drill Holes & Cut Hangers
A 30 degree angle is what I went for. Choose a drill bit to fit the diameter of the plastic hangers. Clip the plastic hangers to appropriate size with pruning sheers. Make sure they fit snugly into holes. If not, adjust drill bit size.
Step 3: Mount on Wall and Get Organized!
Use a directory archiving program like "CD Catalog Expert" to generate a database on your computer as to what is on all of those discs! Sort onto the board, potentially packing into those old 50-packs you have lying around, or other archival methods (boxes or bins).
Now, with a bit of luck, you can actually put your hands on that file (that you JUST KNOW you burned to disc) when you want it! What a great feeling!
Even this small board can keep up to 5 terrabytes of data (relatively) safe from being scraped across a sandy floor under foot and lost forever! (it can happen, believe me!) :D
