I was recently in my little theater room where I have over a thousand titles stored on shelves. When I started some room dusting (that’s rare) I noticed small transparent bits all over the shelves and floor. My first thought was that I had been invaded by termites and what I was seeing was their discarded wings.
On closer inspection, I discovered the mess was small plastic pieces that had fallen from the plastic covers on my compact disks. They were literally falling apart.
Many of the cases are now over 30 years old so I guess there is not much I can do. In fact, I just read the many stores are no longer carrying CDs. Streaming is all the rage now.
