What is the difference between primary and secondary sources?

Primary sources are told in first-person perspective. Secondary sources are made out of compiled information from primary sources, for the most part, and told in third-person perspective. An example of a primary source would be a journal or diary entry by a person who lived and experienced something during a particular time period. A secondary source could be an internet article written about some particular event.
