Google News Blog – Credit where credit is due:

"News publishers and readers both benefit when journalists get proper credit for their work. That can be difficult, with news spreading so quickly and many websites syndicating articles to others. That’s why we’re experimenting with two new metatags for Google News: syndication-source and original-source. Each of these metatags addresses a different scenario, but for both the aim is to allow publishers to take credit for their work and give credit to other journalists."
