There are a few books that can be unanimously placed in the ‘You Should Really Have This in your Library’ category by Web designers/developers. DOM Scripting by Jeremy Keith, in my opinion, is one of those books. From reading the few words on the cover (along with the endless supportive references from other developers) I knew this would be a great resource before I began it.

Getting into DOM Scripting by Jeremy Keith
One of the many reasons I love this book is the way it’s written. It’s as if Jeremy Keith is sitting across a coffee table with you, just chatting about the DOM and explaining why certain techniques are considered best practice. The book is very easy to read and things are explained in a way where you don’t have to go back and re-read sections very often.
