RSS and Atom: Understanding and Implementing Content Feeds and Syndication by Heinz Wittenbrink

The style of the book is succinct and precise. The information is densely packed but well structured, making it both readable as an introduction and overview, but also highly functional as a reference. The author is authoritative but friendly in his style, and peppers the text with interesting examples and pertinent URLs. This book has been written for content professionals, web developers and marketing teams who want to understand what RSS and content syndication is, how it works, what it can for them, and how they can get it up and running. It assumes a solid knowledge of XML and how the web works, but is not intended to be the exclusive province of the technically minded.
