Saving the past

Popular Mechanics tells of the hard work needed to preserve our past - especially if the medium has left the marketplace.
Even recent stuff may not last long.
The Library of Congress subjected identical copies of Paul Winter's Earthbeat to extreme conditions and had wildly different results: One of them turned entirely transparent, while the other seemed relatively intact. But many early CDs (the format was first released in 1982) are already starting to go, meaning the format could have only a 30-year shelf life if professionally produced, and less than that if burned, because of the organic dyes used in the process.
Let keep those memories alive.
