Caldecott? Newberry? What's the difference?

When I asked my husband to hand me the Caldecott Medal Winner book, he looked at me like I had lost my mind! "What is a Caldecott Medal, and how am I supposed to know that?"

The Caldecott Medal is an award given by the Association for Library Service to Children each year to a children's picture book. The Caldecott Medal is based on illustrations. It is the most distinguished medal that a picture book can be given. According to wikipedia, there are certain criteria that must be met:

1. The book must be published in English in the United States the preceding year.
   


2. The illustrations must be original work.



3. The artist must be a citizen or resident of the United States.



4. The book must be considered for the artistic artwork employed.
   


5. The book must display respect for children's understandings, abilities, and appreciations.
   


6. The book must be a self contained entity, not dependant on other media for its enjoyment

When a book is awarded with a Caldecott Medal, you will see the Caldecott Medal on the front of the book.
The first Caldecott Medal was awarded in 1938 to Dorothy P. Lathrop for Animals of the Bible.
The most recent Caldecott Medal was awarded to Erin E. Stead for A Sick Day for Amos McGee.
The year I was born, the Caldecott Medal book was awarded to Marcia Brown for the book Shadow. Can you figure out what year I was born? What book was awarded the Caldecott Medal book the year you were born?

Like the Caldecott Medal, the Newberry Medal is given annually to the most distinguished children's book the previous year. Unlike the Caldecott, the Newberry award is not given just for illustrations. The Newberry award was the first award given to a children's book.
The first Newberry Medal was awarded in 1922 to Hendrik Willem van Loom for the children's book The Story of Mankind. The most recent Newberry Medal was awarded to Clare Vanderpool for the children's book Moon over Manifest.

If you were in charge of giving out the Newberry Award, what book would you choose, and why?
