Hi Brian,
Unfortunately there are rather few true ethnographies of higher education. Besides Stevens' book, I can also highly recommend Michael Moffatt's Coming of Age in New Jersey, which is really the classic ethnography of college life. More recently, Rebekah Nathan has written My Freshman Year, which compliments and updates Moffatt's book well.
More common are interview-based studies, which, though not strictly ethnographic, do provide a bit more in-depth detail than the numerous statistical, survey-based studies. Of these, the most notable are:
Susan Blum, My Word! Plagiarism and College Culture
Mary Grigsby, College Life Through the Eyes of Students
Michele Lamont, How Professors Think
Dorthy Holland and Margaret Eisenhart, Educated in Romance: Woman, Achievement, and College Culture
Kathleen Bogle, Hooking Up: Sex, Dating, and Relationships on Campus
Helen Lefkowitz Horowitz, Campus Life: Undergraduate Cultures from the end of the Eighteenth Century to the Present
Richard Light, Getting the Most out of College
Ken Bain, What the Best College Teachers Do
Also look out for a forthcoming book by Elizabeth Armstrong (Michigan) and Laura Hamilton on gender and the reproduction of social class in higher education.
