What is a Secondary Source?

Secondary sources offer an analysis or a restatement of primary sources. They often attempt to describe or explain primary sources. Some secondary sources not only analyze primary sources, but use them to argue a contention or to persuade the reader to hold a certain opinion.  Examples of secondary sources include dictionaries, encyclopedias, textbooks, and books and articles that interpret or review research works.
