Q. What are the origins of the term "for us, by us" or FUBU?
Start with the Library home page and select the Databases tab, there are a few sources you might check:
Gale Virtual Reference Library, Oxford African American Studies Center, Oxford Reference Online
I searched Gale Virtual Reference Library for “for us, by us” and "black arts movement" found an article that seems to have an answer to the question and a citation to the original source.
