One of the reasons Margaret of Anjou continues to be so maligned by novelists and even some writers of nonfiction is that much of the material that is available about her (especially online) is out of date or based on dated or discredited sources. Happily, a body of careful research about Margaret is slowly growing. Here are some recent books and articles about her and her family:
