Prism99: Thanks. Yes, I know the boxes are not good and I appreciate you mentioning it in case I did not know :-). I've decided against the comic boards due to my research on them being "acid free". I received suggestions in one of my posts to wrap the comic boards in muslin since I was concerned. But, rather than go through all that I decided to stick with my boxes (since they work for me pretty good and I already have the shelving for them) and line the boxes with muslin - LOL. Of course, I haven't gotten around to it yet :-). Thanks for the input!
