Patrons may receive automatic updates of the new material we post on our website by subscribing to our new RSS/XML feed, which link is posted below and on our homepage.

If you unfamiliar withthe topic of RSS/XML feeds, we suggest you conduct a web seach on this term using one of the Internet's search directories, such as Google. In a nutshell, RSS, sometimes known as Really Simple Syndication, is a popular means of sharing regularly updated content (such as news headlines) without requiring readers to constantly visit a Web site to see what's new or to subscribe to an email distribution list. RSS "feeds," or summaries, contain titles, short descriptions, and hyperlinks to longer articles or Web pages, as well as a linked reference back to the originating site. Links in RSS feeds are updated automatically.

To use RSS, you will need a special RSS news reader or aggregator that will allow you to collect and display the RSS content we post. We do not provide the required news reader or aggregator on our website, but via the Internet you can locate several different news readers that are available, many for free (see for example, for a list of web-based news aggregators or for a list of aggregators by platform). Most news readers are applications that you download and install. Others are Web-based services you sign up for that work inside your web browser.

To subscribe to our RSS feed:
1. Copy the URL/shortcut that corresponds to the topic that interests you.
2. Paste the URL into your reader.
Some aggregators will allow you to simply click the RSS icon below from which it will automatically identify the element and add it to your reader.

Please note that by accessing CNN RSS feeds, you agree to our terms of use listed below.
