Originally published in 1929, Hall's Psychoanalyzing the Twelve Zodiacal Types is a somewhat misleading title. By reading Halls other works, one will gather he has a solid understanding of human psychology. But this book does not venture too far into the psychological world, and for the most part remains an astrology book more than a psychology book. The book is laid out typically, with each sign getting its own chapter, and in groups according to their class (i.e. cardinal, fixed, common). I feel that the descriptions for each zodiac is not too far from what you would find in other well written (and understood) astrology books. This book is concise and to the point and makes no claims of right/wrong, better/worse. The use of this book is more for those who are practicing nativities and the like and who are, perhaps, looking for an alternate means of assimilating information. The zodiacal descriptions are all based on the Sun sign which must be considered when making an accurate reading of a horoscope. While the information in the book is probably just as accurate as most other authorities, I would not say this book is a neccessity.
