Since the Objectivist Metablog republishes most of ARI’s press releases, I created an RSS feed which allows you to feed those press releases to your newsreader/website:

Please note that the feed contains a copyright notice reproduced verbatim from ARI’s press releases. You will have to follow the rules in their copyright notice if you want to publish it on your site.
