Google is extracting quotations for politicians and celebrities from news sources and featuring them at the top of the Google News results page for certain searches.
For instance, a search on "Barack Obama" brings up a quotation by the Democratic presidential hopeful, and clicking on his name under the quote takes you to more pages of his quotations. You can then search within just the quotations from there.
"As part of Google's mission to organize the world's information, we've been hard at work making quotations in news articles easy to search and browse," the Google News blog says. "You can now more easily keep track of what your favorite politician, actor, or sports star is saying. You can even search within their quotes for specific topics."
I could find quotations for Obama, Hillary Clinton, John McCain, President Bush, and Vladimir Putin, but not for Bill Clinton or some major actors. As for sports stars, this is what Tiger Woods had to say: "I learned my lesson there with the press. I'm not going to say anything."
