Information about the past can be gathered from a variety of sources. To fully study a historic event, it is important to examine all available sources of information. These sources include both primary and secondary source material.
Primary sources are the most authentic way to study history. When researching an event in history, historians rely almost exclusively on primary sources since these materials were created at the time the event took place. The creators of these documents were often direct witnesses to the events.
The following are examples of primary sources:
Secondary sources are images or descriptions of the past created sometime after the events in question. The creators of secondary source material did not witness the events directly, but often rely on primary source material in their work.
The following are examples of secondary sources:
The photographs and films available on the Through a Lens: Dieppe in Photography and Film Web site, although digitally reproduced, are primary sources. They are copies of original photographs and films created by individuals who were present at the raid on Dieppe or at later commemorative ceremonies.
