So that's maybe 320,000 US Letter size pages. Assuming 70KB/page, I make that 21GB or 30-ish CD-ROMs (or a mere 5 DVDs, if they're cheaper over there these days). Assuming a scan time of 10s per page, you will need over 37 days of scan time to get all the data (I'm guessing you can run it in unattended mode...) I assume you are going to make this available on a web page or two, I think I can download it all in just about 60 hours. Looks good to me :-) I think if you PDF stuff that has been G4'd you'll find that the size increase is minimal. Stuff I've scanned comes out of the scanner as PDF but *not* G4 compression, that's why it's a little bigger. I believe that Acrobat 5 can go from PDF to other stuff, but I think we only have V4 kicking around, so I cannot check. No problem - just supply TIFFs and I'll happily turn them into PDFs myslef (just this once, you understand :-) ) Seriously, if this works, I'll dig out my four linear mm of fiche and send them over (always assuming they're not already in your stack).
