I grabbed this book from the library in preparation for a computer skills test for a staffing agency. I thought this book would teach me how to use the MS Office suite better, but there's very little in this book that a regular, everyday user of MS Office products wouldn't already know. (The same is true of the computer exam, actually. If you've worked with MS Office products at all, you'll be fine. I overprepared...) This book devotes more space to Word than to any of the other programs--perhaps because the target audience isn't one that demands high-level Excel skills or the complex use of Outlook.
For a regular MS Office user who would like to learn more about the programs, I'd recommend "The Missing Manual" series. Those books don't assume that you're a novice at MS Office and actually teach you things you don't know.
Read most of the Microsoft Word and Excel sections to prepare for testing to help jog my memory. Easy to understand and has very easy instructions to follow. Good for a novice. Very Windows friendly, assumes the world runs on Windows. It doesn't.
