Primary sources are original records created at the time historical events occurred or well after events in the form of memoirs and oral histories. Primary sources may include letters, manuscripts, diaries, journals, newspapers, speeches, interviews, memoirs, documents produced by government agencies such as Congress or the Office of the President, photographs, audio recordings, moving pictures or video recordings, research data, and objects or artifacts such as works of art or ancient roads, buildings, tools, and weapons.
These sources serve as the raw material to interpret the past, and when they are used along with previous interpretations by historians, they provide the resources necessary for historical research" (Source: Using Primary Sources on the Web, a website created by the History Section of the American Library Association designed to help researchers locate, evaluate, and properly cite online primary sources). Scholars analyze and interpret primary sources in secondary works, particularly scholarly monographs (books) and peer-reviewed journal articles. Secondary sources need not be scholarly, however, and can include popular magazine and newspaper articles, non-academic biographies, textbooks, or websites. Please contact your professor or me if you are having difficulty differentiating between primary and secondary sources.
