The decade of the 1970' s could be characterized as period of feminine consciousness, a period of concentrated awareness of social and economic imbalances and injustices, which led to thorough examinations of educational materials. Sexism was discovered to be rampant, though perhaps not unexpected, throughout reading materials intended for young people. Many studies examined the frequency of appearance of male and female characters, which a majority focused on sex role stereotyping.
