Yes, check this book out from your library sometime.
This is a fun little book that lives up to its title. The stories about each of the artists are very interesting. I bet my artist friends (you know who you are) would even get more out of it than me.
I thought it was most interesting to hear the artists describe how they came up with ideas and how they practiced drawing. None of them made it look easy. And I LOVED the little "dummy books" that some of them had made. I learned a new term.
I have to admit I hadn't heard of all of the artists. I enjoyed looking at the list of ALL the Caldecott winners on the back, and I was sad that more weren't mentioned in the book. I will definetly use this research to reserve more books for me via the online catalog of my library.
