Input:
If you have some old slides lying around and you don't know what to do with them, buy this Kodak Carousel, especially if you have an old slide projector that still works. You can stack them on your bookshelves and label them on the outside and inside as well. It would be good to put them on your computer, too, for permanent digital storage. But at least buy the carousel. The metal storage box holds more, but maybe you don't have that many.
