I had all of mine stored in plastic sleeves, artwork and all, in a zippered binder made for such, but it grew too heavy. So, I went on eBay and bought 400 CD changer and started the tedious job of loading them, one at a time, twisting the knobs to spell out the title, etc. Now, they are not in order as I've taken some out over the years to make a duplicate copy for the bedroom CD player, so...I have all of the covers, etc. alphabetized in an large index card file, just need to take out all the CDs, match them up, wipe the memory slate clean, somehow, on the changer, and re-enter them all. Phew...not sure when!;-)
