Historical Sources tell us something about history. There are two main types of historical sources: primary and secondary sources.
A primary source comes from the past. It is an original object or document; first-hand information. Primary source is material written or produced in the time period that you may be investigating. Primary sources allow the researcher to get as close as possible to what actually happened during an historical event or time period.
If I tell you something I am the primary source.
Secondary sources are interpretations and evaluations of primary sources. They are NOT evidence but rather commentary on and discussion of evidence. Consider secondary sources as second-hand information.
If you tell someone else what I told you, you are the secondary source.
Secondary sources can be articles in newspapers, magazines, books or articles found that evaluate or criticize someone else's original research.
For example: A Roman coin made by the Romans is a Primary Source, but a drawing of a Roman coin made in 2003 would be a Secondary Source.
