Digitization Setups

The Overhead was a Better Light digital back scanning system. It was essentially a digital camera that operated like a scanner, moving from side to side to capture an item. It was in room 216. It was a bit persnickety about focus. It had no live view, just a screen where you could see a preview scan. It was faster than the flatbed scanners but nothing as fast as a digital camera capture system. If you need to locate images done with that machine, an easy place to look is at the Woodward diaries.

The Bookdrive was an Atiz product, using two digital cameras pointed at two sides of a v-shaped book cradle. The cameras we used on that station were Canon EOS 5Ds. It had serious focus problems. We re-structured it so that it shot things against the capture bed just like our other mounted-camera systems. The lighting was torturous that way. For these reasons, we stopped using the setup. Also, the Canon EOS 5D was a Mark I, which wasn't compatible with EOS Utility, which we use as our live-view capture interface (see Cameras.


Peculiar Collections

  • Captured with batch scanner, in black and white: u0008_0000003 (transcripts only)
  • Captured with slide scanner: u0001_2007004
  • Captured with batch feeder attachment to Epson flatbed: u0002_0000002 (some, probably the disbound ones)


We used to keep tracking data in separate files. We switched to integrated tracking data exported to separate files in January 2013. Both files are stored in the archive as .log.txt. The easy way to tell them apart is how many columns they have. Old-school tracking data files have dozens of columns, some to record info about audio. New-form tracking data files have less than 10 columns.

Random Info

  • Yes, we once took an exacto knife to some surplus copies of old yearbooks. They're probably still back here. Some have been digitized already; others are awaiting the go-ahead to continue the collection.
  • Some material is captured against a white background. These are flatbed scans. If it looks dirty, that's because the flatbed lid was. The batch feeder attachment was especially prone to dirty gray tracks.
