Good evening, Museum-Ls - You need a vapor/moisture barrier between the 
plywood and the volumes. Something that will not allow any vapor/moisture 
to pass thru (and therefore no acidic contamination). My favorite 
affordable solution is heavy duty aluminum foil from Costco. Any seaming 
necessary is accomplished via folding the edges over twice.

...to store large bound newspaper publications.  We had considered pallets 
but instead are opting for 4X4 covered with plywood.  I know there should 
be a barrier between the plywood and the volumes. I am hoping for 
suggestions from the list....
