How does a secondary source differ from a primary source?
A secondary source interprets and analyzes primary sources. Secondary sources are one step removed from the event. Examples include a book about the effects of World War I written years later by a historian; a journal article which interprets another scientist’s experiment or medical research; a biography of an author, actress, or scholar. Some types of secondary sources are book reviews, histories, literary criticism, and encyclopedias.
