Primary sources in the arts and most humanities disciplines are original, creative works. These include literary and musical compositions, paintings and studio works, photographs, and much more. Primary sources in history are the surviving records—traditionally texts but also material cultural remains and visual imagery—that date to the period under consideration (e.g., historical newspaper articles; memoirs and personal narratives; government documents).
In the arts, humanities, and history, secondary sources are based on primary sources. Common formats include monographs (books) written for other scholars and peer-reviewed journal articles. Scholars leverage primary works to answer unresolved disciplinary questions, but also to question disciplinary consensus and challenge stale narratives.
