Scanning turns out fine. We use it for some 1845 – 1875 letterpress business ledgers of the family that founded the town and the local iron industry. Important documents. Letterpress can be difficult under any circumstance; faded inks, feathery. I think the people who are doing the transcription are much happier with the scan that they can manipulate it. Scans can be stored on the computer and searched. Can be printed out: folded into paper airplanes, lunch place mats for fundraisers. We use the wand for any printed material when we don’t want to compromise the spine.
I see researchers using wands on large maps in bound atlases. They scan sections.
I can’t say what we bought as I won’t be in the historical society for a few days. About 3 years ago it was just under $100. New ones are probably better than the one we bought.
