Since I was getting all nostalgic last weekend with the cassette tape photo shoot, I figured this might be a good follow-up. Have a quick look at c-90.org. It's a "in progress" catalogue of all sorts of cassette tapes from all around the world. I think I might actually have some that they don't have in their DB, so I'll probably hop over and contribute. So go find those old tapes and if you've got pristine ones that are not in their database, make a contribution or two.
