I have said many times that the only way to put an end to the under-appreciation of female writers is to start in school. If children are brought up to believe that only male writers are important, and in particular that boys do not need to read books by women, they will take those attitudes into adulthood where they are much harder to shake off.
My friends at For Books Sake have been taking a look at gender representation in English Literature examinations in the UK. They found to their horror that the syllabus is becoming more male dominated (and more white) rather than less. As the politicians are fond of saying, something must be done.
