A secondary source is a document that interprets or analyzes primary or other secondary sources. It is second hand information, i.e., one step removed from the event.
Examples include:
- books such as biographies, histories, overviews, works written with the use of other sources
- literature reviews
- book reviews
- journal articles (which are not primary reports of new research)
- newspaper & magazine articles (which do not give first hand accounts)
