By happenstance, author and activist, Charles A. Preston appeared on my Twitter timeline through the retweet of someone I follow, and I consider myself lucky to have found his amazing resource for Black History (this month and every month of the year). The multi-folder Google doc is chock full of information about many aspects of Black History from Afro-Futurism to Zora Neale Hurston and many others in between. I believe he is continuing to update it. When using his folders, remember to give him credit as well as linking to his Twitter or website.
In addtion, you can follow Mr. Preston on Twitter or visit his Website.
