A search of the Columbia Libraries catalog for <"anarcha-feminis?" OR anarchafeminis?> yields 12 results. I know you like to use Wikipedia as a warrant, so check out their definition of Anarcha-Feminism.
In other words, it would be helpful if you would establish ANARCHA-FEMINISM and ANARCHA-FEMINISTS as subject headings, since the concept is like a hundred years old. I don't care whether you hyphenate or not, but ANARCHAFEMINIST wins the Google Fight.

PS ANARCHA-FEMINISM is on Sandy Berman's suggestion list, so it's not like I'm the first person to suggest it.
