Google News, the aggregation platform for news from thousands of news sources, has a short shelf life. After news stories are posted, they expire after 30 days.
However, all these stories, plus millions of older articles never posted, reside on Google News Archives.
Last summer, Google announced plans to archive major news sources. It recently completed most of The New York Times and all of TIME magazine as Josh Cohen of Google News told me in this interview.
Besides the searchability of all this content, there is a very cool tool that allows a graphical display of search results. Check out this chart of Barack Obama’s news coverage. As far as we can determine, the charts have been introduced late last year to little attention. It’s cool. Go ahead, "Google News Chart" yourself!
In the interview, Josh explains how Google works effectively with publishers who have subscription services or pay walls, explaining how special Google links to The Wall Street Journal and Financial Times provide visitors with a free, one story "snack."
