Data entry is the act of transcribing some form of data into another form, usually a computer program. Forms of data that people might transcribe include handwritten documents, information off spreadsheets from another computer program, sequences of numbers, letters and symbols that build a program, or simple data like names and addresses. Some people perform jobs that are exclusively data entry, while others, like programmers, might have to occasionally enter data.

To archive human knowledge and to make information more accessible to the world, multiple projects are currently digitizing physical books that were written before the computer age. The book pages are being photographically scanned, and then transformed into text using "Optical Character Recognition" (OCR). The transformation into text is useful because scanning a book produces images, which are difficult to store on small devices, expensive to download, and cannot be searched. The problem is that OCR is not perfect.
reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.
But if a computer can't read such a IMAGES, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.
High Transcription Accuracy
Answers to reCAPTCHA challenges are used to digitize textual documents. It's not easy, but through a sophisticated combination of multiple OCR programs, probabilistic language models, and most importantly the answers from millions of humans on the internet, reCAPTCHA is able to achieve over 99.5% transcription accuracy at the word level. See for yourself!
The samples below show a comparison of the accuracy of standard OCR versus reCAPTCHA transcriptions on a medium quality scanned document:

About 200 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books.
