I just finished reading DOM Scripting, a great javascript book. I am very familiar with all aspects of PHP and MySQL, and have read a Head Rush Ajax.

Now I am looking to move onto more advanced javascript, I have grown to love PHP 5's object oriented programming and would like to learn more about Javascripts. Could someone please recommend a good advanced javascript book.

Most of the ones I have found that say they are advanced javasciprt, just deal with DOM or CSS, both of which were covered very well in DOM Scripting.

Thanks again.
