Will Google proof goofs?

Over at InfoWorld Tech Watch, Ephraim Schwartz raises an obvious question about Google's plan to digitize and make searchable thousands of books from major libraries:

Who's going to do the proofreading?

I realize there are high speed scanners available but I wonder how accurate they are?

If the average printed page has 550 words on it and a scanner is 99 percent accurate that means there would be 5.5 errors or misreads of letters and or words per page. That's a lot of errors to find. ...

I know from first hand experience scanning can be somewhat problematic. lower case h's and n's can look awfully similar to a non-human scanner.

Imagine a first time online reader of Hamlet puzzling over the line, "to be or hot to be"?

Elsewhere, the Detroit Free Press points out some potential real-world limitations in the service's utility.
