Query: Less Than Impressed

I had one of the authors as a professor for my speech development class, and this was the assigned book.Although the authors are clearly knowledgeable, the text fails as both a learning tool and a reference book. If you actually read the book through, the writing is awkwardly casual and filled with less than helpful examples. The chapters titles and heading make finding specific information difficult, and the index is not user-friendly. There are also several times where statistics provided seem contradictory.Although this edition contains several valuable additions, overall the previous editions are better resources.
