I wonder if putting a white-on-transparent OCR overlay on top of the scanned layer lets you find errors just by looking at the black spots.
You might do better by putting a colored transparent text overlay over a colored text base, such that one can spot the color change where the (additive please not subtractive) colors "don't mix."
For example a green base text layer with an additive red transparent text OCR overlay layer give you a yellow letter where the colors mix -- "hit", but green or red where there is a "miss". One can still read what's there in any case, but "hit vs. miss" would become pretty obvious, I would think.
I'd say it depends more on how well you can match the exact font, kerning, etc, of the original book across multiple browsers, DOMs, and OSes. Even with precise letter positions from the OCR, not simple. Be interesting if someone can pull it off, though. Also, personally, I would not touch that particular color combination; I've got a moderate case of protanomaly[0], and that color combination is camouflage. -Bob [0] Somewhere around 5% of the population has some sort of color blindness.
