Multicultural Women's and Gender Studies is a multidisciplinary field and research materials can be found in many places.
"Feminist activist grey material is abundant on the Internet. In a range of ways feminists are lobbying for women’s rights through the Net, in areas such as: reproductive rights; domestic violence; women and politics; global issues; women and health; sexual harassment; and women of color." (p20)
"In considering feminist grey literature we have argued that non-commercially published material has always had an important place within feminism. This has been a necessary part of communicating women's experiences and ideas in a society where women's voices and women's writing have been suppressed." (p25)
