In historical research, a primary source can be any source of information created at the time of a historical event or by a direct participant in or observer of an event.
Primary sources can include memoirs,diaries, correspondence, interviews, photographs, newspaper or magazine articles, film footage, news broadcasts, official documents, speeches, maps, artifacts, and works of fiction or drama.
What constitutes a primary source depends entirely on the subject of research. For example, John F. Kennedy's Profiles in Courage would be a secondary source in a study of John Quincy Adams or Sam Houston, but it could serve as a primary source if the topic of study were Kennedy himself.
Choose historically appropriate keywords. For example, use "Great War" instead of "World War I" to locate documents discussing the war during and just after it occurred. You may also consider different terms that might have been used to describe the same event from opposing sides or perspectives. Searching for the names of particular people or places may also be effective, but consider how the names might be presented (last name only, or as part of a title) and how country and city names have changed over time.
