The Cellulose Acetate Microfilm Database has been built to help libraries and archives in assessing the danger to their microfilm collections posed by acetate based films.
When libraries and archives started systematic microfilming for preservation purposes, acetate film was still the predominant product. It began to be replaced with stable polyester in the 1980s, but the legacy it leaves behind is a serious one. The only way to slow the deterioration rate – thus buying more time to assess more interventive options such as duplicating, digitising or refilming – is cold storage.
