»In which we back up

I backed up all of my CDs today. That's all twenty years of buying CDs (from The Wailing Ultimate (an anthology of Homestead Records' superstars, cheap at $10 from Phantom of the Attic), to Wilco's Sky Blue Sky, which came with a bonus DVfuckingD jam session), piled on to about 120' of shelf space. They now take up three (logically) massive hard drives which fit into less than 1' of shelf space.
Most of the CDs which I was super-duper-extra excited to find -- say something by the Brotzman/Drake Duo, or the Ubu Dance Party double-disc tribute to Pere Ubu -- have close to nil resale value, because until that special someone comes along to go through a similar frisson of joy, these just take up shelf space. Then again, my ultra-limited Duophonic promos from the 90s do not have the value I thought they would hold -- they are not going to put my kids through college. The corresponding elpees and singles, though -- those have some cash value. Still, the time has come to move these out: they take up too much wall space, and space is precious.
