I love this book. I have been a GIS user for 10 years and really only came upon this book last year. It really helped me to improve my maps through thorough explanation of methods of map development and great examples. It didn't take me long to get through the book, but the information was valuable: clear and concise. It gave me changes I could implement the very next day at work- and I did. I wish I had found this book 10 years ago.
