Do you think the wood warning also apply to wooden book cases enclosed with glass doors? Much of my collection has been stored that way for over 100 years! I haven't noticed a problem yet!

Of course everything has been well-protected from heat and humidity. I believe that's very much more important than worrying about "archival quality" or "acid-free" storage. I think the wooden binders would probably be fine if not loaded too full for (dry,cool)air circulation.
