Query: Good introductory book

Getting to Know ArcGIS Desktop is a very good introductory book to ESRI's latest software. It is easy to read and the exercises are easy to follow and are a great teaching tool. This book covers basic GIS tasks and will provide a solid foundation for future learning. However, I do not think this book will be useful to persons already experienced with ArcGIS as advanced topics are not covered. Overall, very good tutorial.
