SCANNING
Drawings, photos, maps and other materials
are copied with specialist film cameras up to 1m x 1.5m or digitally
scanned up to a maximum size of 0.91m x 30.5m.
16mm and 35mm photographic microfilm is
utilised for recording books, fine illustrations, photos and catalogues.
Microfiche is used for catalogues, parts lists and drawings. Aperture
cards holding 35mm microfilm are used mainly for archiving drawings
at higher quality than Microfiche and offer customers space to
add typed or hand written text on the card. Duplicates are produced
for all formats.
