Best way to organize 6000 albums?

I currently have about 2000 albums arranged alphabetically. I purchased a collection that was randomly numbered ( each new album owner purchased received the next available number ) and came with a DBASE file as an index. I have a few thousand in boxes gathering dust. I am wondering if anyone has ingeneous ideas as to how to have access to all albums and make them easy to browse through. The least amount of space used the better. I guess I prefer parallel to the wall as it is easier to flip through them and see the covers ( for guests ). I'm thinking of a vertical rack shaped like the ride the zipper with rows of album storage trays, it can be rolled vertically through placing each row at the appropriate level ?? any ideas welcome...any diy out there in this vain.
