Reply #12: I built my own shelving unit...

[regnaD kciN]

Floor to ceiling, and along the length of one wall between the door and the sliding glass window. Maybe 3.5 to 4 feet wide. To make sure I had enough room for all our CDs, I spaced the shelves close enough so that the space between each was just tall enough for a jewel case, plus a little space above so one could pull a disc out with a fingertip. With that tight fit, I managed to get all my CDs circa 1998 on the one unit.

Of course, soon thereafter, DVD-Audio came out, switching to a jewel case about an inch taller than a CD. And record labels started packaging boxed sets in cardboard boxes with paper sleeves instead of multi-jewel cases. It makes the boxes thinner, but also tall enough to keep from fitting on those shelves by about 1/16". :-(
