The function of secondary sources is to interpret, analyze, critique and comment on primary sources. Thus, they can be described as at least one step removed from the event or original work. Secondary source materials are usually in the form of published works such as journal articles or books, but may include radio or television documentaries, or conference proceedings.

A source can be primary or secondary depending on how it is being used. Often newspapers are considered secondary sources as journalists report, analyze, and interpret events and the experience of others. Newspapers can also be used as primary sources. If you are researching how American attitudes on welfare spending have changed during the past twenty years, newspaper editorials can serve as primary sources of public opinion.
