Re: Microfilm longevity



That's because you are using a non-preservation copy.  The standards clearly state that the LE (life expectancy) is based on a storage-only "non-use" original or silver halide duplicate.  Microfilm that is used for retrieval is highly suseptable to damage and is, therefore, not considered covered by the stability or longevity standards.

The standards may say Five hundred years, but as I researcher I've had 50 year old microfilm break in the microfilm reader rendering the film useless for my purposes.
