RSS Feeds
RSS stands for Really Simple Syndication or Rich Site Summary, depending on who you listen to. Basically, it's a different way for displaying the content of a webpage and is generally used in conjunction with an piece of software called an aggregator. This monitors any feeds (RSS links) to see if they've changed so you can quickly and easily see which ones have been updated since you last looked. They can also let you see the content instead of or before you visit a page. List Books has an RSS link (which is compatible with Atom as well, courtesy of Feed Burner) for the latest listings so you can stay up to date quickly and easliy or integrate it into your own website.
