Scholarly articles are usually written by scholars or professionals in a certain field of study. The information provided can either be to further their field of study, keeping recent research, findings, and news up to date, or to simply allow the general public to enlighten themselves. These types of sources can usually be trusted as they subjected to peer review before publication, as well as, obligated to cite any of the source material they utilized. Which, not only provide credibility for their own work and the work of others but, your own as well if you use these sources.
