I did not read the entirety of this book, given that it is a textbook. However, I think there is a very good range of information, spanning from different types of personality models and how they were created, personality research methods, traits, biological underpinning of personality, and the stability of personality across a lifetime. I haven't read other personality textbooks, so I can't compare it to any others, but this textbook seems like a great starting point to anyone interested in personality research in Psychology.
