After the horrific shooting at the Emanuel African Methodist Episcopal Church in Charleston in 2015, Chad Williams, a history professor at Brandeis, began the historian-crowd-sourced #CharlestonSyllabus, which in just a few days amassed several hundred titles. Here they all are in a WorldCat List: bit.ly/BC-charleston. Some more recent titles worth pursuing: Caste, by Isabel Wilkerson; The Disordered Cosmos, by Chanda Prescod-Weinstein; We Do This Till We Free Us, by Mariame Kaba; Stamped from the Beginning, by Ibram Kendi.
