RSS feeds are a simple way to view content without having to visit a web site to check for updates. When new journal issues are posted online, users subscribed to the RSS feed will automatically receive an update with links to individual articles plus the abstract for each article.
To view a RSS feed, you need a news reader program. A list of news reader programs can be found at www.allrss.com/rssreaders.html.
If you have other questions or comments about RSS feeds please send the remarks to APS using the contact form.
