RSS (Really Simple Syndication) is an XML-based syndication format for distributing content on the Web. Many kinds of content can be distributed using the RSS format including search results, topic alerts, and new records that have been added to the database.
Information released in RSS format is called a feed. RSS feeds can be read by internet browsers or "news reader" programs. The latest versions of Microsoft’s Internet Explorer, Apple's Safari, and Mozilla’s Firefox support RSS feeds without downloading special software (see the browser's Help for instructions). News reader programs are available for a range of computer platforms, many at low or no cost.
