Cd storage..what's an audiophile to do?

I use a Tansu cabinet in the living room. It has five drawers that are suitable for CD's (on end) and will hold approx. 250 CD's per drawer. I place a length of wood in the bottom/back of each drawer so that the CD's do not extend to the very back. The drawers are closed when we are not searching for music and everything is out of sight. Any chest with many shallow, sturdy drawers will work the same. Ours is almost half full and I will have to figure out additional storage space eventually. I separate classical from soundtracks from popular music from World, though everything is a mess right now.

Mezmo: I have been looking for a way to store CD's that will be burned from our old cassette collection (and isolate them from the rest of the CD's as well). I assume that these things look like books and can be placed on a bookshelf and will look into them. I don't plan on keeping the cassettes, so will have to make backup copies of the rare, popular (to us) and out of print ones and could use a smaller book to store these.
