The publishing house Verso have compiled a list of key readings for undergraduates (available here). The 24 books are inclusive of works by Marx, Harvey, Lukes, Zizek, Balibar, and Anderson. This list would also be helpful and informative for post-graduate students and academics alike.
Admittedly there are a number of these publications that I have not read as of yet, but I’m thankful to have discovered this list and to begin reading. I’ll probably start with “The Curios Enlightenment of Professor Caritat” by Steven Lukes. It sounds fascinating! Racecraft: The Soul of Inequality in American Life” by the Fields sisters is also now on my “to read” list.
