At one time I thought the best way to preserve a book long term was to place it in a ziplock bag and put it somewhere dark. I rather figured no moisture, no mold, no nothing and therefore the book would be better preserved. Let’s just say….Wrong!
Old books need to “breathe”. When locked away without ample moisture in the air, the natural materials become brittle. Pages of the book become easily torn and the bindings begin to break down.
