A bit out of date now, particularly the spread on the largest man-made structures. The Sears Tower is no longer the tallest building in the world, and the spread also includes the World Trade Center twin towers of NYC, which obviously are no longer standing.
so reading this book in 2015 there are a few things that are out of date, but over all its an enjoyable kids book. my daughter enjoyed leaning about the different things. it's a cute read and I would read this book to my kids again.
