First, Elizabeth Bird, the grande dame of librarian bloggers, gave Boys of Steel: The Creators of Superman a luminescent review.
Then, months later, she called it ultra-cool.
Now she wrote that she wouldn't mind if it got a Sibert Award (given by the American Library Association for the most distinguished informational book of the year).
Just the fact that she wrote that is award enough. High praise from someone in the know. Thank you, Elizabeth.
