Bob,

I don't have nearly the number of DVDs or CDs that you do, but I started to run out of room and was also looking at options. Additional furniture was not really one of them so I've put everything in binders. Maybe binders are a option for you too. For my CDs I use basic three-ring binders with pages that are designed to hold CDs. I pull the CD info from the jewel case and slip it in the adjoining slot on the page. Each page has eight slots. For DVDs I found some faux leather cases specifically for DVD storage. Each sheet will hold the art from the DVD case and two DVDs. I cut down the space used by my DVDs and CDs by about 75%. I found all the supplies at Staples or Office Depot.

If my solution does not work for you then there is always the option of having some fun making a little sawdust! If you do, please share your design.
