I've been wondering what the acceptable ranges are for the proper storage of signed documents, primarily autographed records. I happen to live in an area where the summer can have tremendous swings in humidity and I don't want to risk damaging some of my signed albums. I also am considering storing in a basement safe but the basement can get a bit damp. I had an album that got wet and the signatures bled which is understandable but I'm more concerned with regular humidity in a house or storage area. Thanks in advance for your advice/input.
