Gaylord Archival Newspaper Preservation Box Safely store newspapers containing important family and historical information before they start to deteriorate Archival quality: acid-free, lignin-free, passed P.A.T. (Photographic Activity Test), pH 8.0-9.0, buffered to resist acid migration Deep lid keeps out dust, dirt and damaging light, while metal edges add strength, support and a sleek look When storing multiple newspapers in one box, layer them with archival-quality tissue paper or place each newspaper in a newspaper sleeve or folder from Gaylord Archival (tissue paper, sleeves and folders sold separately) Your family history deserves the same level of protection used by the world's leading cultural institutions
