Microfilm
is normally used for a number of purposes.
It is carried out as a means of Document
Management, in that it allows users to look
at documents that are infrequently consulted
while removing the necessity of holding
the original on-site, it is also used as
a means of preserving documents by making
them available to researchers without exposing
the originals to wear-and-tear. Perhaps
the most common use of Microfilm/Reprographics
is in Vital Records Protection, in that
it allows a cheap copy of rare or important
documents to be made and held off-site,
thus ensuring the preservation of the information
on those documents.

While Microfilming/Reprographics
is a very cost-effective solution it is
best, as is the case with Scanning, to work
towards only having to film each document
once, as although Microfilming is cheap,
it is labour intensive. Once filming is
complete on each reel it should be developed
on Silver Halide stock and marked clearly as a 'master' film. The master film
should be treated as an archival document
and kept as true to the original as possible.
Multiple copies of the master should be
kept in a number of locations, preferably
off-site, as this offers some protection
against possible destruction/damage. Other
films for use by researchers, or in file
rooms, should be created from themaster
film on seperate stock, and replaced when
worn out by once again copying the master.
Copies should not be made of copies.
There are 2 primary formats of Microfilm,
16mm and 35mm (not counting microfiche,
which is a varient in the printing process).
Traditionally archivists have advocated
the use of 35mm film, for reasons of clarity
and resolution. It is also possible to get
colour film in 35mm which is obviously useful
in capturing documents for which colour
is an important part, for instance maps
and drawings. There are 2 main criteria
in choosing a format, once is the size of
the document and the other is whether colour
is required or not. For all intents and
purposes 16mm film is perfectly acceptable
for filming all documents up to A3 size
provided they are in black and white. Another
consideration is that there are no 35mm
cameras in Ireland available for commercial
use, so filming in 35mm would involve contracting
work to the UK. In instances where 35mm
is required it is probably best to consider
Scanning/Digitisation as an alternative.
