It was late October 2000. A wide-eyed graduate student at the time, I had recently decided to write my dissertation on Black soldiers and World War I—what would eventually become my first book, Torchbearers of Democracy (2010). Now I was embarking on my first research trip to the University of Massachusetts-Amherst, whose library houses the papers of W. E. B. Du Bois.

I had, in advance, gone through the online finding aid. A nondescript reference to “Du Bois World War I materials” grabbed my attention.This might be promising, I thought.
