Book sampling: MS how to

Before I purchase at Amazon, do any of you, for some odd reason, have any kind of Dummies/How to/Look You Idiot sort of books on using MS Office 2007. Or anything focusing on MS Outlook?

About half our office is upgraded to 2007, and gradually finding out all that it will do. Or, finding out all that it will do that you didn't intend, and perhaps didn't want.

I've decided to get some books that may assist me in getting an overview of this system that the online help seems unable to do. No, they are not all Dummy books. Two were interesting, focusing on Outlook and GTD organizational system. But...

Do any of you have books you can recommend, and any I might peruse before purchasing?
