When searching the streaming collections, you may have to try different search strategies, as "Feminism" or "Gender Studies" is vague and huge topics. Adding subsequent terms, can help because these might also be found in the descriptions of the videos, and will help narrow down your search.
For example: In America Latina en Video - you can search "mujer" and films regarding women will come up in the results list.
Another tip is to use the "Browse" or "Subject" search of the streaming video database that is being searched.
For example: In Docuseek, click on "Subject." If you scroll down the page you'll see a listing for "Women's Studies."
