Primary sources are first-hand, authoritative accounts of an event, topic, or historical time period. They are typically produced at the time of the event by a person who experienced it, but can also be made later on in the form of personal memoirs or oral histories.
Anything that contains original information on a topic is considered a primary source. Usually, primary sources are the object discussed in your paper. For instance, if you are writing an analysis on Upton Sinclair’s The Jungle, the book would be a primary source. Just because a source is old does not mean it is a primary source.
Examples of primary sources include:
Secondary sources analyze, review or critique primary sources. They often include an analysis of the event discussed or featured in the primary source. They are second-hand accounts that interpret or draw conclusions from one or more primary sources.

Academic or Scholarly Articles
Scholarly literature is written by and for researchers, faculty or scholars who are experts in their field. People who write for academic journals are employed by colleges, universities, or other institutions of education or research. They submit articles to the editors of the journals, who decide whether or not to publish the article.
The most prestigious academic journals utilize the peer-review process. This means that, before an article is accepted for publication, it is reviewed by several experts in the field, who suggest possible changes, check the facts, and recommend to the editor of the journal whether or not to publish the article.
These articles tend to use scholarly or technical language and include full citations for sources. The best way to find articles from academic journals is to use library databases.
