What is a primary source?
The Oxford English Dictionary's definition of the word "primary":
A primary source is an original document or object, something that was created or written during the time that is being researched. It is first-hand information from someone who was present at the scene of action or witnessed an event when it occurred. It gives us an up, close and personal view of a particular event or time.
Examples of primary sources:
Artifacts and Relics such as pottery, furniture, clothing, coins, implements, etc.
Census and Demographic Records
Creative works such as poetry, drama, fiction, music, art
Experiments, clinical trials
Historical documents such as charters, constitutions, etc.
Journal articles reporting original research, empirical data, statistics, etc.
Legal documents (laws and legislative hearings)
Letters and correspondences
Maps and Atlases (Those created at the time of the event such as battelfield maps created during a war are primary sources but those created later are secondary sources)
Papers delivered at conferences
What is a Secondary Source?
The Oxford English Dictionary definition of the word "secondary":
A secondary source interprets and analyzes a primary source. These sources are one or two steps removed from the event or occurrence. They may include comments, discussions, reviews and explanations; they are considered second-hand sources because they are based on the primary source. A secondary source may contain quotes, graphics or pictures of primary sources in them.
Examples of Secondary Sources:
Books that discuss or analyze a topic
Indexes and Abstracts
Journal or magazine articles that interpret or discuss previous research findings
Newspaper articles that interpret a topic or event (Articles that report first-hand about a topic are considered primary sources).
Reviews of art, books, movies, plays, etc.
