Better than the humidity of Ohio!

Store them as close to 70 degrees as you can, the dryness will just be an added bonus, since moisture is a killer on old and rare papers.

I have newspaers (which are printed on cheap acidic paper and usually require conservation) from the Japanese surrender, German surrender, sinking of the Edmund Fitzgerald, and a few others. The humidity here in N.E. Ohio wreaked havoc on them. One from the death of Gen. Patton was destroyed, as was the front page celebrating the 50th anniversary of the end of the Civil War. The others had to be professionally conserved. I got a great deal on that, the Historical Society paid for it when I agreed to "loan" them. I'll probably never ask for them back, as nobody else in my family has the same passion for history as I do.
