At first I really liked this book, but the farther I progressed, the more confusing it got. By the time I got to somthing practical, I was completely lost. A couple of times, when I was having trouble understanding something, I went back and re-read a preceding chapter, but that was not enough. I was reading this on my own, rather than in a class, so I had nobody to ask for clarification when something was confusing. Maybe it would be okay in a course.
For the theorems, he doesn't state the asssumption. Instead, the reader is expected to know them because of the variable names. For example, because "p" was chosen to represent a prime number at some point in the book, I think that it is always a prime number from then on. However, he never stated that this is the case, so I'm not sure it is true. Sometimes a variable would start off fairly general, but he would add some assumptions about it for a later theorem. For subsequent uses of that variable, I would not know whether the variable was being used in its more general or more specific sense. The uncertainty about the meanings of variables just got to be too much for me.
A glossary would be helpful. In particular, it would be great to have a list of all the meanings of "primitive".

I used this textbook for an introduction to Channel Coding class I took (graduate level). I think that the material is difficult, but this book is remarkably clear, considering that. I had no experience with Galois Fields or any of that kind of math before starting with this book, but I was able to grasp it. I think the main thing missing in this book are good summaries for each chapter, giving highlights of the important stuff. Sometimes it's hard to get an overall picture of the material, I got bogged down in math sometimes. Visually, the book is beautiful, good fonts, charts, etc...
