Scholarly literature is written by researchers 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.
Academic publishing is the process of contributing the results of one's research into the literature, which often requires a peer-review process. Original scientific research published for the first time in scientific journals is called the primary literature. Patents and technical reports, for minor research results and engineering and design work (including computer software), can also be considered primary literature.
