It makes sense to me that higher resolutions should do better, so I'll run a comparative test when I get the leisure. Does anyone else have some experience on this issue?

The "auto color select" that I used on my first attemp, apparently saw the "yellowed" pages as color so the scanning was at 150 DPI. Had I forced it to BW, it would have been 300 DPI.
I plan to compare various resolutions and see how it affects speed and OCR accuracy.
At the 150 DPI, I had a lot of confusion between t, l, 1, i, f, & sometimes J. Also "cl" was sometimes seen as "d" & "ib" as "th". I think the 300 DPI should take care of most of these. Some interesting confusion, like "lot" being seen as "tol".
More later.
