A great reference and fascinating in its own right. I got this mainly to use as a reference when writing stories, but it's also a great book to browse through. I'm somewhat familiar with some of the Native American cultures in my area, but regarding those of most of the New World I'm fairly ignorant.
To me there's nothing more interesting than people, so psychology, history, sociology, and anthropology are all endlessly intriguing. As well as a lot of information, this book has a lot of illustrations in color of everything from household implements to religious symbols to weapons to clothing. Well worth reading and keeping as a reference.
