"As one of a few institutions to have consistently collected pamphlets published during the 19th and the first half of the 20th centuries, Harvard holds tens of thousands of these pamphlets, covering diverse and eclectic topics. Areas currently covered in this digital collection include Latin America, World War I, Sociology, the Boer War, and Brittany. As additional pamphlets are cataloged and digitized, they will be added to this online collection."
