Great book
The narrator possesses a refined and compelling voice, and the author's writing style stimulates the mind. The author uses a tremendous amount of detail to avoid unnecessary/inaccurate generalizations and intentional/unintentional misinterpretations. However, the author executes this feat without allowing the reader to feel lost in mundane facts. I enjoyed the author's use of rhetorical questions to explore the viewpoints of persons who oppose his assertions. Overall, an informative and invigorating read. I highly recommend this book for anyone who has ever asked, "Why did certain people and cultures end up with so much, while others ended up with so little".

Guns, Germa and Steel Audio Version
A great audio adaptation of a great book. I listened to it on my commute to work.
I have the actual book, but had no time to sit down and read it. If you are very busy, audio versions of books really work well.

Guns,germs, and steel on disks
This book is full of info most of which is confusing and useless but had to read it for school and the disks really only give the important info and skip the rest. over all product is great!
