Interesting
Format: Paperback
This was a very interesting read. I read it cover to cover in 2 days. It was fascinating. Many details within matched up to various interviews and stories I have heard. That being said, I did find it odd all the "human" like aliens appeared to be Caucasian. I realize most the descriptions included multi colored skin tones, but all the pictures appeared Caucasian. So the universe with multi dimensions has no diversity?? Also, why were the most malevolent beings the most terrifying in appearance? That seemed a bit odd. That they would just so happen to be the ones that also look the most scary? Also, I looked up some of the resources and such used and they were charging exorbitant amounts to hear about their contactee interviews or be apart of star seed ascension or whatever. It's just, if everything is to be believed, wouldn't they want everyone to experience the path to enlightenment? I mean we all have to earn a living, but $40 just to hear one session?? I scoffed at that. All that being said, I am very open minded and well, ready to ascend from this plant, like, yesterday.

Incredible source of information on extraterrestrials and where they come from
Format: Paperback, Format: Paperback
This book Has changed the game and is a breakthrough for those of us who want to know more about life that exist in our shared universe. The author has brought us an in-depth view of species and beings from all throughout the galaxies. A profound read full of information on extraterrestrials like never before, we get to have them all in one book! The author has done an amazing job with his research and is knowledgeable and convincing I believe he has evidence and enough resources to make this book believable to readers and one we can trust. Truly a work of art I have learned so much more than I ever had on this subject and really look at this book as a blueprint for humans to get know all of names of the extraterrestrials and where they come from.

A very interesting read
Format: Paperback
The book has a straight forward and simple layout. I liked the variety of info they had on different "species", some probably real, and some very questionable. Since the information the author uses relies on MUFON reports, it assumes all reports people gave over the years are true. It loses me when it gets into the more malevolent groups like reptilians and then believe it or not, dragons, which are the ultimate evil controlling them.

very interesting compilation of our best knowledge
Format: Kindle
I’ve known Craig for a number of years and have read all his books. While the “Autobiography of an Extraterrestrial” series was ostensibly fiction, flash bulbs kept going off in my head, past life memories perhaps, and a strong sense that I had been there. This Species Almanac is more an attempt to compile our best knowledge and understanding of our place in the Universe and who the neighbors are.

you will start wondering if this is real of sc-fi
Format: Paperback
Great book to read and see what potentially could be there. Its raw description of races without any bigger context, but this is what almanac is. Its not a story book. It gives glimpse of possibilities and and insight into political structure in the universe, what is good, what is bad - but that's just a glimpse without going deep in it leaving reader with impression: "OK, i want more!" and "ok, were to get more details on governance and technology, metaphysics, religion"? It's well organized. One thing that will come after reading is question: Is it really something real that is hidden in government secrets or its new branch of SC-FI?
