Come on, really? Do the Library of Congress's accelerated aging tests performed in high temperatures mean nothing to you?
This thread has some of the worst advice I've ever seen on the CGC forums and that's saying something.
There are three musts in comic storage: COOL, RELATIVELY DRY, DARK. These are not hard to remember.
These three things are more important than the "mylar vs. polybag" debate or the "shiny side vs. dull side of the backboard" debate. This is because HEAT, HIGH RELATIVE HUMIDITY, AND EXCESSIVE EXPOSURE TO UV RAYS DESTROY COMICS.
Polluted air also destroys comics. You can alleviate the effects of pollution by using boxes made of Microchamber paper or by inserting Microchamber paper into the books themselves.
To the original poster: Don't store your books in the attic, or in the :censored: basement. Store them in an interior closet in an air-conditioned room in the house where there is not a lot of variation in the three musts. If the books are junk that you don't care about, then why ask the question? Just set the damned books on fire and save yourself the storage problem.
There, you have the best advice you're going to get on the topic. Listen to it or ignore it, but my work is done here.
For the love of christ, now I understand why Sal is starting nonsense threads with allcaps and no punctuation. Not that his threads before had any great comic topics being discussed, but at least they were written in proper English. Look what you've driven him to.
And me, for that matter - you've made me end a sentence with a preposition, I'm so worked up!
I agree with this wholeheartedly. If the comics are worth storing, store them correctly.
