They look more interesting than they really are. The titles and descriptions suggest that the contents are real verifiable anomalies and some are but, too many entries are merely references to a note someone found of some entirely ridiculous claim made by some moonbat up to as far back as around 150 years ago. Those things that are interesting real anomalies are often not thorough discussions of the subject leaving one to try to find obscure references elsewhere to learn more on the subject.
If the properly documented thorough discussions were put in abridged forms of these books at a price that reflected the actual amount of information then contained in them then they would be a must buy. The present form/price of these volumes left me somewhat disappointed.
