Holocaust historical data goes online

The world's largest collection of Holocaust documents is going online.

Israel's Holocaust memorial, Yad Vashem, is teaming up with Google to make its photographs and documents available and searchable on the internet. The first 130,000 photos hit the web Wednesday.

Viewers can also contribute to the project by adding their own stories and documents about family members who appear in the online archives.

Google says it is using experimental optical character recognition technology to make documents searchable and easier to navigate. The new feature upgrades Yad Vashem's already formidable website.

The launch comes a day before the United Nations marks its annual Holocaust remembrance day.
