Adrienne, I wonder about Mylar inadvertently creating harmful micro-environments too. Would anyone know if a better alternative would be enclosing the newspaper pages in large-format acid-free folders, them placing the folders in large flat boxes?
I have a large clippings collection, and feel I should prioritize this expensive treatment to those that have evidential/intrinsic value. Does anyone have any opinion about storing the rest of the clippings in acid-free folders interleaved with acid-free paper, in document cases?
This group has a great span of knowledge and experience, looking forward this thread continuing!
