Other people to credit:

At O’Reilly:

Our biggest thanks to Mike Loukides at O’Reilly, for starting it all, and helping to shape the Head First concept into a series. We continue to be thrilled to have an editor who is a Real Java Guy. And a big thanks to the driving force behind Head First, Tim O’Reilly. Lucky for us, he’s always thinking about the future, and rather enjoys being a disruptive influence.

A huge thank-you to the clever Kyle Hart for figuring out how Head First fits into the world, and for launching the series. And to Allen Noren for a great job on the O’Reilly Head First pages. Finally, to Edie Freedman for designing the Head First cover look and feel. With Head First, you can judge the book by its cover.

Our intrepid beta testers and reviewers:

Our top honors and thanks go to John Zoetebier and Gustavo Torreti (aka “Morpheus”). You are amazing and energetic and smart (and picky, picky, picky) and we can’t thank you enough. Gus, you always made us smile with each and every message you sent.

And as always, thanks especially to the javaranch Trail Boss, Paul Wheaton.
