Sitepoint is one of the best, in my opinion, tech publishers around. I always find their books easy to follow and full of really useful information.
If you're a beginner at building web sites, you want to make sure you don't make the same mistakes others, like myself, have made when teaching ourselves about web design and development. The main thing you'll want to learn is how to build a site using xHTML and CSS, and Sitepoint have a new book out called, shockingly, "Build your own website the right way using HTML and CSS" written by Ian Lloyd.
