An organisation called End Sexism in Schools is researching the discrepancy in male- and female-authored books featured in school curriculums and they are looking for volunteers to help do internet-based research - even if it’s just for 30 mins. Thought there might be some mumsnetters who can help out?
I’m not affiliated with them, just thought it was interesting! So far, they are finding that kids are studying about 3 books written by men for every book written by a woman
