There is a big difference between this newer edition and manly of the scarce but available older hardcover editions. At the end of this article I have provided a few links to several older editions that collectors may want to consider for purchasing, you can make up your own mind. - My opinion is simple. This newer paperback edition is one of the worst examples of reprint and bastardization of one of the 20th century's masterworks. Yes inevitable as the industry is about selling out to the lowest common dollar, this would not have happened if Hall were alive to see his great book reduced to a college reader text. Trust me even the smaller 80s editions in hardcover will be well worth the couple of extra dollars that may be incurred.
And if you are knowledgeable of Manly P. Hall and this text, you already understand. I have had this for many years in my personal collection. I believe it is one of top ten books you can read before you die, and one of the classics ever written in human literature.
Even modern Publisher Llewelyn has nothing but high praises for 'Secret Teachings'...
"Simply put, this is the most beautiful and complete occult book ever published. It represents a lifetime of research into the mythology, symbolism, and magical practices of countless cultures. From the secrets of Isis to the teachings of mystic Christianity, nearly every occult dogma imaginable is represented here. The book is full of giant illustrations, some of which fold out into a magnificent two-page splendor. This is the definitive guide to secret societies, famous figures, and more a must for every personal library." - Llewellyn New Times
There are editions available on the open retail market these days if you just want a reader copy, and there are older collectable editions that are worth thousands of dollars, that is if you can even acquire one. I hope the listing below gives you a fair crossection to consider.
