And this is why you don’t store floppies next to acidic paper.
@rallias For context, the floppies were fine - it's the paper that degraded from being in contact with the floppy's plastic.
But also, we don't use it as often anymore! Lower-quality acidic paper was far more common up until the 80s/early 90s. Acidic paper is cheaper but a lot stuff uses decent-quality paper now.
