To establish the legitimacy of a President is not sufficient reason to "dig out the fragile (micro) fiche" ? What would be a good enough reason for you to trouble a lazy bureaucrat to do their job? This I gotta hear!
“All master microfilm created today uses a polyester plastic backing. Under proper storage conditions, today’s film has a 500 year Life Expectance (LE). The older acetate films have no more than a 100 year LE. “
Under proper storage conditions, any records that were microfilmed in the 1960’s would still have a very viable Master. Even the service copies of the newspapers that obama’s “birth announcements” are in are, for the most part, still legible. I refer to the ones in the very worst condition of course.
Microfilm Masters are not terribly fragile if stored properly.
Here is a site that has good info:
