It's November and I'm finally getting around to chiming in on this topic.
Our facility has climate controls, but due to the nature of the building we cannot maintain anything close to what the standard is (ie Harvard's 50F/30% RH). That being said, we do store any and all objects -- realia, microform, books, paper, art, a/v, etc.
