I started working at my current location after exhibits using some of the collections objects were already installed. The people who created the exhibits did not know a lot about care of various materials. They placed paper items, including old seed packets, books, and single sheets of paper, directly in old wooden prune crates with nothing between the paper and the wood. The prune boxes are hung on the walls like shelves, and covered with plexi. The plexi cover does not fit closely to the box, which is probably a blessing because at least the acids from the wood aren’t confined in a sealed space. I’m most concerned about the paper directly in contact with wood. I’m hoping to do something unobtrusive to counteract the acid from the wood, since I have already gotten resistance after suggesting that the boxes be totally lined. Would a small piece of buffered paper or tissue underneath each paper object help in keeping acid damage at bay?
