One of my neighbors, a black, retired UT Professor of Engineering who has suffered/endured an incredible amount of racial discrimination in his life has offered the following books on racism.
The Strange Career of William Ellis by Karl Jacoby
Black Indians by William Loren Katz
Bind Us Apart by Nicholas Guyatt and
The Sea Captain's Wife by Martha Hodes
According to my neighbor
"1. Top....This one is a true story, most of which takes place in TX, so anyone interested in some TX history, with its varied perspectives, might find it to be interesting reading.
2. This treats Blacks in North America pre Civil War, and their relationships with American Indians.
3. Excellent and fairly detailed American history related to issues of race.
4. .....It’s a true story from someone’s diary, but it has a great exposure to northern and southern thinking regarding race in years preceding and during the Civil War."
