The new addition is not user friendly. Signing naturally 1-6 was organized more efficiently and the DVD setup was more user friendly. I have compared books with others in my class and I am the only one with pain it my copy, but it is there. On about 10% of the pages there are smudges of all colors. Something at the printing press went wrong because my book is new. If this book is required for your class, there's no way around it, but look for an older edition.
