On the Dallas PHP Users Group site today, there's a new, quick book review from baron covering Wiley Publishing's "Beginning Web Programming with HTML, XHTML and CSS".
This is a hands on book useful as an HTML refresher and introduction to XHTML, CSS1, CSS2, JavaScript and general web related topics including; site design, page layout, hosting, and search engines. This book contains many valuable links to external tools and sources of information such as syntax validators, browser archives, royalty-free image sites, sites with detailed CSS information and demonstrations, and much more. The books contains a comprehensive reference section which provides a fast lookup of XHTML elements, CSS properties, special characters, mime types, etc.
His review isn't all too positive, unfortunately - there were code errors in the examples, and some subjects were just touched on too lightly. He notes that it's a good refresher/learing tool, but for anything more advanced than that, look elsewhere...
