Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
Really Simple Syndication (RSS) is a way to subscribe to receive headlines and synopses of updates to blogs, general news sources, and almost everything else that’s available on the Web. Basically, an RSS document, or “feed,” is an XML file that has a link to the full article or blog entry along with the title and a synopsis.
RSS feeds are provided by many web sites, including news sites, blogs, company and organizational sites, and almost anything else you can think of. Subscribing to a site simply requires linking to an XML file at the site. Your RSS reader periodically reads the file and the file’s contents describe the current headlines.
