I'm using a filing system suggested by SteveK in
another thread. (Sorry, I haven't replied to your last email yet, Steve.) It relies on
sleeves and
storage boxes made by Univenture.
I bought the sleeves from
Sleeve City, which had the best prices. The storage boxes that Univenture makes to hold the sleeves are not elegant, as Steve points out, but they are good looking and designed to fit the sleeves perfectly. I bought them directly from Univenture, which appears to be the sole seller.
I'm putting the boxes with sleeves in some nice-looking, but affordable wood-laminate lateral filing cabinets, which I bought from Office Depot. (I can't find the exact ones I bought now, but
this model approximates the look, minus the handles.) I reinforced the bottom of each drawer with some leftover shelving from another project, because they're designed for hanging folders.
There's space in each drawer for filing folders with the original artwork. I'm keeping a small number of keepcases to reconstruct any disc into its usual form--mostly for double-dipped DVDs that I want to sell and replace with a new version. The rest of the keepcases are going out the door.
Everything is being filed alphabetically and tracked by DVD Profiler. Using three filing cabinets, I figure I'm able to store up to about 3,000 DVDs.
The rest of my collection is filed in normal keepcases in my 11-foot wide entertainment center, which has lots of shelf storage, and on permanent wall shelving. Both have reached capacity.
