[BKARTS] Book cleaning problem

I ran into this same problem many years ago and received the same analysis as Minter and Sanders from Paul Banks who was the Chief Conservator at the Newberry Library at the time. PVC reacts with Cellulose Nitrate (pyroxylin). As I recall the best solution I found was spraying the covers with Krylon (spray acrylic) just to reduce the stickiness.
