> reCAPTCHA digitizes books by turning words that cannot be read by computers into CAPTCHAs for people to solve. Word by word, a book is digitized and preserved online for people to find and read.
I wonder where i heard/got the impression that it wasn't really being used for this much anymore. Maybe from when most of the recaptchas most of us saw switched from scanned books to google street view photo crops. And I was also surprised by the implication that google's algorithms really needed human help for visual recognition of almost exclusively strings of 0-9. I would have thought that would be a pretty well solved problem.
Anyway, somehow I got the idea that recaptcha wasn't actually providing much OCR help anymore, but maybe I just made that up.
