Microfilm. Depending on who you ask, properly stored microfilm will last
at least 100 to 200 years. Some experts claim it may last up to 500
years. And you never have to worry about the media being unreadable
because of changing technology. In a pinch, even a good magnifying glass
will work.

Many archives, both government and private, use microfilm for long-term
storage of important documents.
