E. P. Thompson's The Making of the English Working Class exercised a substantial influence on the South African academy and acted as a key shaper of a “history from below” movement in the 1980s. While Thompson's influence in South Africa has been celebrated, the limits of his circulation are less frequently explored. This article takes on this task by placing The Making alongside Steve Biko's I Write What I Like. Biko was a major figure in the emergence of the Black Consciousness Movement (BCM). The article compares the interlinked formations of which the two texts formed a part—the BCM displaced white radical intellectuals, who retreated into class analysis as an analytical alternative to race. The article also examines specific copies of the two titles found in South African libraries and uses the different patterns of marginalia as a way of tracing the individual impacts of the two texts.
