Verified Purchase(What is this?)
This review is from: NGK Infopedia 2013 (National Geographic) (Paperback)
I purchased the 2011 edition and that has been my Grandsons constant reading companion. The 2013 version is equally as good if not better, produced with the usual high quality Nat. Geo photographs and well written, I highly recommend this for any young reader, it's even good for Grandads.
