Word recognition software is used when a book page is scanned, to see what words are on the page, but when you have billions of pages, not every word is going to be recognized & accounted for. This is where reCAPTCHA came in.

The reCAPTCHA service is a user-dialogue system originally developed at Carnegie Mellon University's main Pittsburgh campus. It uses the CAPTCHA interface, of asking users to enter words seen in distorted text images onscreen, to help digitize the text of books, while protecting websites from bots attempting to access restricted areas.[1] On September 16, 2009, Google acquired reCAPTCHA.[2] reCAPTCHA is currently digitizing the archives of The New York Times and books from Google Books.[3] As of 2009, twenty years of The New York Times had been digitized and the project planned to have completed the remaining years by the end of 2010.[4]
