Earth Book

This book is from 1990, so I was surprised that some of the libraries in my system still had it in circulation. Upon reading it, however, I had a hard time deciding whether it was out of date or not. Some of the information has probably changed, but I'm not sure that the ways that we look at the Earth from space have changed too much, even 25 years down the line. I think some of the picture quality has probably improved but I honestly don't know...and I doubt a kid would either.
