A secondary source is a source which interprets primary sources. A secondary source is written or created after an event by a person who was not present for the original event. It may include primary sources and offer an explanation and synthesis of them.
Examples of secondary sources might include textbooks, scholarly articles and monographs, biographies, scholarly books, encyclopedias, and more.
