A scholarly journal is a periodical written by and for professionals in a specific discipline in which is published original research to disseminate new knowledge in the field. These journals are competitive and many more articles are rejected than are published. Many, but not all, of the journals are peer-reviewed, a process by which other researchers who are specialists in the area being studied review the research prior to publication and make suggestions for changes and edits prior to publication. For this reason, research articles from peer-reviewed journals are considered to be at a higher standard than those that have only undergone an editorial process by a paid editor rather than the more rigorous review by other specialized researchers in the field.
