Primary and Secondary Sources
There can be a difference between the time when the document was produced and the time the event actually took place. It is important to distinguish between them.
The author of the document may be dealing with an event that is happening or has just ended. This would be the case, for example, with a newspaper article from 1929 that reports the collapse of the New York Stock Exchange or a photograph that shows an event. These documents are primary sources, that is, first-hand sources.
The author of a document might also write about a fact or an event many years after it happened. This would be the case for a historian who analyzes records of the past (primary sources) and then writes a book on the subject. These documents are secondary sources, that is, second-hand sources.
