I have always been a big admirer of Google, they always have exciting projects on the go, I like the fact they are the most innovative company on the planet, driven by creativity, leveraging a vast number of talented people to make all kinds of large records accessible to everyone previously not possible.

One of the ugly sides of the internet is hate groups.  Quite a significant amount of this is antisemitism, and quite a significant portion of antisemitism is holocaust denial.

Google are now inviting those who had family lost or survived the holocaust to submit pictures and data to this site as a big collaborative project, to stop history from being forgotten or revised, especially as the number of people survived this ordeal are getting few.   Google use a fair bit of their own OCR software to turn scanned text into searchable data.
