many people have jousted at this particular windmill
this is a huge time-consuming project
I have literally thousands of sheets of DEC fiche from multiple sources
scanning at that kind of volume doesn't scale. you have to clean an qc every sheet
even with a production scanner. It took me most of a day to do the little bit of xxdp
fiche a couple of weeks ago on a manual positioning Canon microfilm/microfiche scanner
I just bought another high-end scanner, which isn't running yet. It uses glass carriers
for each sheet and I have about 6 carriers.
I was hoping it could handle IBM punched-card sized fiche, but I've not been able to
find a carrier that big. I have a rather large backlog of those as well.
