"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."

I think there's a strong relationship between reCaptcha and this group
- via standards and accessibility.  :-)
