Interdisciplinary Study of Issues Surrounding Social Justice: From Frederick Douglass to Martin Luther King Jr. and Malcolm X [PDF ebook] 

This book pulls an array of voices together to understand the convoluted times of 2016 to 2021 and the unique times of COVID-19. The killing of George Floyd, Breanna Taylor, and the death of John Lewis are events that highlight a historical revival for numerous social justice issues. This book stresses the importance of sociologist W. I. Thomas’s work: "if you define a situation as real, it is real in its consequences" – otherwise termed the world of subjective reality. This helps explain what happened on January 6, 2021.
