I can feel your frustration, since I am always looking for sources. I am surprised that you did not find anything in jstor. I would suggest that you do different key word searches. Also look up prominent feminists. I am positive you will have more hits than you can imagine.
Outrageous Acts and Everyday Rebellions is a classic by Gloria Steinem. This should be helpful. Or do a key word search in jstor with the above name.
Routledge Encyclopedia of Women: Global Women's Issues and Knowledge should also get you started with bibliography. Read few articles and see what helps you.
Finally, you can use a lot of work on power as well, people like Foucault. Or you can use people who have worked on gender studies.
