    Reposted, as I don't think anybody saw it the first time around:

    Question: What exactly does this bending from humidity look like? I store my
    discs in my room, and I have noticed that on the stuff I've had the longest, the
    back inserts seem *ever so slightly* bowed in some cases, yet the paper still
    seems strong, and you have to look realllly hard to see it. I always chalked it up t
    oa byproduct of aging, as my room isn't terribly humid, but as I AM in the
    northeast, should I invest in a dehumidifier?

    I would think that CD inserts would likely only be affected by extreme humidity, since they are "protected" by the plastic CD case and kept in a flat position. LP's are a bigger problem, especially when the shrink wrap is left on.

    In the most severe cases, the bending of the paper will begin to take on a "scalloped" look, rather than just a simple curve, but that is generally a very extreme case, and not one that I've run across very often with most people's storage. When I **have** seen it, it's usually due to spilled (or otherwise accumulated) liquids.

    In dealing with archived materials in general, though, it's always good to have a dehumidifier running. Anything you can do to lessen the extremes of climate conditions in the storage area is (to quote Martha Stewart) "a good thing"!!

    -Hope this helps,

    -Kevin

    Just to add to what I originally posted, I keep my LP's and CD's in the basement near the furnace area. The furnace supplies the heat in the winter and the central air in the summer so humidity is pretty much banished for the most part.

    David,

    Where I live the humidity is always somewhere between 50-100% and have never experienced any bending, scalloping, warping on my Cd's paperwork, even on some that are 17 years old.;)

    I suspect that if you have central air and heat, you won't experience any problem with your CD artwork, as there won't be drastic changes in temperature (causing condensation) or humidity.

    I lived in one apartment with window units, however, and I did get water/humidity damage on my CD inserts, despite the jewel case. Generally the damage was confined to the edges of the booklet, and on the back tray card behind the spindle. The worst cases invariably involved CD artwork with lots of reverse printing on a black background. Sometimes the pages would stick together, and get damaged when I tried ever so carefully to pull them apart.

    I would recommend keeping your CDs away from direct sunlight. Place them so they aren't blown on directly by the vents or window units. Certainly you don't want them where a surprise shower could damage them through an open window. If you don't have central air, I would invest in a dehumidifier.
