Many libraries have decommissioned their card catalogs. These large, usually wood pieces of furniture are now being turned into many awesome things. I've seen card catalogs turned into rolling coffee tables, recipes boxes, wine holders, and sideboards. What I have never seen was one turned into this most excellent end table. It's not a stretch from the other uses, but I love how this turned out.
The best part of this table... it splits apart and becomes modular. You could have extra seating!
You can buy this from Merles Vintage on Etsy.
