University students do an incredible amount of reading.

Given the breadth of topics they must cover before graduating, it’s interesting to see the trends in required-reading lists.

A recent Quartz post explored some of these lists, citing The Open Syllabus Project, which collected over 1 million curricula over the past 15 years.

Students at America’s most prestigious universities — those in the top 10, according to US News & World Report — must endure the rigors of some very dense subject matter. The topics of the titles cover issues such as philosophy, politics, and war.

These books were found on university syllabuses from Princeton, Harvard, Yale, Columbia, Stanford, University of Chicago, MIT, Duke, UPenn, and Brown.
