A feed is a regularly updated summary of web content, along with links to full versions of that content. When you subscribe to a given website's feed by using a feed reader, you'll receive a summary of new content from that website. Important: you must use a feed reader in order to subscribe to website feeds. When you click on an RSS or Atom feed link, your browser may display a page of unformatted gobbledygook.
What are RSS and Atom?
RSS and Atom are the two feed formats. Most feed readers support both formats. Right now, Google News supports Atom 0.3 and RSS 2.0.
How do I use Google News feeds?
To access Google News feeds, look for the RSS| Atom links on any Google News page. These links will generate a feed of current stories related to the page that you're looking at.
