Finnish library uses games to crowdsource indexing

Most internet users have probably come across reCAPTCHA at some point or other in their online travels, notable because it not only helps distinguish human website visitors from computerized bots, but it also taps the human ones to help digitize books, newspapers and old radio shows. Operating on a similar principle, Finnish indexing effort Digitalkoot now offers a series of games by which players can help fix mistakes in the indexing of old Finnish newspapers.
