Curators there place arti- facts in oxygen barrier bags, withdraw most of the oxygen con- taining air from the valve, fill the bags with nitrogen sometimes adding silica to keep specimens dry, and set them in a cabinet where they can be stored for up to 30 years (Jason J. Huggan, Carol L. Anderson, personal communication 2006).	cache/ajb-24.pdf	txt/ajb-24.txt
