For Harriet has a lot of material written about black women and their contributions.
InMotion is a documentary of African Americans and their migration experience.
Not just for Black History Month, read Te-Nihesi Coates blog and Post-Bourgie and particularly this piece that agrees with me on the empty critiques of sayings about “do what you love” and work. Also, the Crunk Feminist Collective, which allows you to both read and financially support the page, which is an excellent idea if you want people to keep creating content unsubsidized by the University of Southern California the way I am.
Finally, The Root has wonderful online reporting; please see this very nice piece on Stokely Carmichael.
