Help Digitize Books for the Web
NPR broadcast a story last week about how we Internet users work to digitize materials for the web. You know all those times you have to sign into different social network communities (like this one) or get past security that checks to make sure you’re not a computer bot trying to spam. You’re given a distorted set of letters to decode and type into a box.
Well, now some sites use something called reCAPTCHA, where two words appear. The first is the regular security code. The second is a real word that scanning equipment found difficult to interpret. So, you’re the interpreter! You’re helping to scan material for the Internet Archive.
The Science article describes exactly how it’s done!
