Both micro-fiche and -film can have an expectancy of 40-50 years and more
with optimum storage conditions. But the word "optimum" can imply a lot.
And of course searchability is a major advantage of electronic forms. As
for "blowing up" the results (pun intended?), certainly you can do that
with fiche or film optically also. And for scanning, yes, the data have to
be captured in any case. But film is a photographic process accomplished
in a part of a second, as opposed to the slightly slower requirements of
electronic scanning (and the greatly longer process of OCR). The time
difference may be slight for a small project, but it can add up to a lot in
a large one. Plus you must consider that the "indexing" of page images –
in wither case – must be done, at least to some extent, manually, adding
additional time requirement.
I am not an advocate of film particularly, but I think it only fair to lay
out some of the positive and negative attributes of both approaches to give
the company the best shot of finding the optimal solution in their specific
context. Certainly, it seems that the electronic scheme is gaining ground
all over the map.
