Negative Positive
Title: A classic!
Review: This is a classic textbook from a renowned scientist. This book is mandatory to anyone that needs an introduction to the complex field of Geomagnetism. There are several other works on the subject but this new (second) edition includes some relevant updates from recent research, turning this one of the best available texts on the subject. My only complain is the huge difference in price between hardcover and paperback versions at Amazon (near U$100) that I found AFTER buying the hardcover edition.
Is the review positive or negative?
