Mastering AutoCAD 2010 and AutoCAD LT 2010

I agree with the reviewer who gave it 2 stars.  I originally learned AutoCAD 2008 and bought this book as a refresher and to figure out the new 2010 settings.  I would NOT recommend this book for a beginner because the mistakes in this book are confusing enough for me when I already know the basics.  There aren't mistakes on every page but enough to be frustrating and momentarily confusing. That's when the F1 key (AutoCAD 2010 Help box) comes in handy. If you already know AutoCAD and just want to figure out the 2010 features and where everything is, this book is written in a good format and will fit your needs.
