Little Pinch of Salt

I’ve noticed CAPTCHAs are now asking you for two words, and didn’t know that the extra effort requested is all about making sure that old literary texts (the crumbling, fading and falling apart ones) can be successfully digitised. Well, I didn’t know that until I read this BBC article.

If you’re using CAPTCHA, you can switch to reCAPTCHA and help to archive old books. Pretty cool.

How reCAPTCHA makes text legible.
