One of the biggest issues I face is when receiving a new version of Microsoft Office, is asking the question, "What's changed and why do I need it?".
Well, I actually bought this book a couple weeks ago, and as a result, have purchased Office XP Professional, which I am thoroughly happy with. This book, Special Edition Office XP helped me understand what the differences in Office versus prior versions are and how I can apply them to my daily work. While the table of contents listed here on the detail page talks about Office 10, it does appears that the book was written on a release candidate beta. The book addresses all the issues I had that Microsoft's own marketing machine couldn't.
Woody Leonard and Ed Bott are both extrememly well known, but it seems their years of experience with Office have paid off, at least from what I am seeing in this book.
There is extensive coverage on all the key areas of Office XP I'd recommend taking a strong look at these key components of the book:the table of contents, the index, the notes, the "cautions" and the tips from Ed & Woody throughout the book. This book is also packed with a lot more than the similiar product from Microsoft Press. I was really disappointed with their product after comparing the two side-by-side. Thanks goes to the authors and the publisher for making my job a lot easier and thanks for an outstanding book.
