THIS was painful, even as textbooks go. Written by robots who were paid by the word, this tediously bloated text was clearly designed to dissuade people from embarking on a career of communication investigation. It is, quite simply, impossible to read this book and ever want anything mentioned within to be a part of your life again.
The writing is both heavy-handed and dumbed down, which is a pretty impressive feat of writing, I suppose. The authors clearly had either no idea what audience they were writing for or each had their own audience in mind. Some of the more advanced topics, like statistical analysis, were written for time traveling cyborg rocket scientists who enjoy performing trigonometry equations while listening to the sound of the breaking hearts of college students everywhere. At the other end of the spectrum, the book spends four pages explaining how to find research literature in an academic library. The fact that the book is VERY dated doesn't help things, even though some of the topics explored are as timeless as the scars that reading this book will leave on your psyche.
In short, if your professor assigns this book, consider dropping the class and trying next semester or pursuing a different major. Or perhaps explore a career in the exciting field of drive thru window operation - some things just aren't worth it.
