One of my local historical societies has a Minolta PS 7000 overhead scanner and we are probably going to scan some older directories that Ancestry does not have. However, we would have no idea how to make those scans searchable as a database (being able to search by surname) as opposed to a full-text OCR that would not even recognize that there are (usually) two columns of information per page. If it's not something we'd be able to do with free or low-cost software, I wonder if scans could be turned over to Ancestry so they could add them to their database?
Would anyone happen to know if it is possible to have the Minolta PS 7000 scan in color, or to have it scan at higher than 600dpi? That's not necessary for directories, but it would be nice for images. I'm not entirely sure if b&w & dpi are limitations of the scanner itself or of the software. It seems that the color might be, and I suppose dpi might be - though I'm not sure why.
"Renders crisp, legible text and clear, sharp halftones up to 600 dpi resolution for 11" x 17" originals, 400 dpi for 17" x 23-3/8" oversized pages using exclusive Micro-Toning System for legible text and clear, sharp halftones." https://www.imageaccesscorp.com/scanners/moreinfo.asp?Brand=...
If it can do at least 600 I'm not sure why it couldn't do at least 600 for 17" x 23-3/8" oversized pages too.
They have XnView v2.25 for Windows.
