How to archive a 16mm film of an RCA 501

A friend informs me that the "cellulose acetate" disease is a problem for museum curators the world over. Not only does it cause photographic materials to decay, but it also causes old fabrics such as "satin" sheets and Hawaiian "aloha" shirts to slowly fall to pieces. Apparently, the acetic acid that's liberated by decomposition is a double-whammy. Not only is it a product of decomposition, but it also serves to hasten the decomposition of the remaining material. Neutralizing or filtering out the acetic acid fumes and storage in cool and dark temperature-and-humidity-controlled lockers seems to be the only affordable preservation measure. Single photographic negatives can have the emulsion carefully stripped off and placed on a polyester substrate, but that seems to be as far as anyone's gone. Wonder if we'll have a similar problem with USB sticks 50 years hence? Cheers, Chuck
