If you pick up a kid's book in the United States that's about a person of color, chances are the character is black. And if the character is black, there's a decent chance he or she is oppressed. These are the findings of a team of researchers from Maine's Bates College. In September the group launched the Diverse BookFinder, a database to help people find books with characters of color. The team aims to categorize all the books published or reprinted in the US since 2002 about people of color. What their research shows is that books about specific groups cluster heavily around specific narratives.
