Ezra Greenspan is a literary and cultural historian who studies the history of print culture in its various manifestations in the United States. He is interested, in particular, in the central activities (such as writing, reading, printing, and publishing) and institutions (such as libraries, bookstores, and schools) of American print culture. His central figure has long been Walt Whitman, but he also has an active scholarly interest in the culture of letters of nineteenth-century African Americans. He is currently working on a comprehensive literary biography of the most important and versatile nineteenth-century African American writer, William Wells Brown. As an undergraduate and graduate teacher, he offers a variety of courses on the canonized and minority literary cultures of the United States.  He is the co-editor of the journal Book History.
