I tried the GCV demo as well and got one mistake "prevent:" instead of "prevents" as it is in the text. But that's the only I could find, which puts it several categories ahead of the txt file.

I'm not sure though whether the IA can get Google to OCR it for them for a budget they can afford. Likely they'd want OCR solutions that have a one-time cost, so volume based SAAS offerings won't work.
