Best book for AJAX development

[kiwicmc]

So, if we assume that I'm fully up to speed on Java, HTML, JavaScript. What would a good book for me to get to assist me with Zimbra development?

I'm thinking something laying out AJAX principals would be good. Any recommendations?

PS:I've got a shelf full of O'Reilly's is there a good one for AJAX?

AJAX books are just starting to arrive. Basic CSS/DHTML/JavaScript is a good start. 3 good books are:

Dynamic HTML: The Definitive Reference (2nd Edition) by Danny Goodman

Cascading Style Sheets: The Definitive Guide (2nd Edition) by Eric A. Meyer

JavaScript: The Definitive Guide (4th Edition) by David Flanagan
