Definition

RSS (formally "RDF Site Summary", known colloquially as "Really Simple Syndication") is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a "feed", "web feed", or "channel", contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that's easier than checking them manually.

RSS content can be read using software called an "RSS reader", "feed reader" or an "aggregator". From Wikipedia


RSS feeds are built-in to almost all web 2.0 technologies, and should be promoted as an integral part of any of these services. Feeds can be displayed
on library webpages and blogs, providing useful links and up-to-date content.
