Primary sources include original content, first-hand accounts, raw data, documents or objects created at the time of study. Primary sources vary dependent upon the focus of study.
For example, primary sources for a historian will include diaries, letters, newspaper article written at the time of an event; for a literary scholar, she may study a poem, a short story, or novel; for a musicologist, she may study notes written by the composer; for a biologist, she will study the findings of an original research project.
Secondary sources interpret or analyze a primary source. A secondary source provides commentary and discussion of a primary source.
For example, a magazine article that discusses a research study that analyzed data collected from a survey about literacy in rural school districts.
Article databases index both popular, professional/trade, and scholarly journals (or peer reviewed).
Peer reviewed or refereed articles refers to the process in which articles are reviewed by professionals in a field of study before being published. A journal's website should explain the publishing process and if it is peer reviewed or not. Many times professors use the term peer reviewed and scholarly articles synonymously.
