Scientific articles and papers are one of the main sources of information in STEM disciplines. They help researchers, professors, and students to stay up-to-date on the latest trends in their field and to access current and developing findings.
The materials, evidence, or data used in yours, or others, research are known as sources. As foundations of research, these sources of information are typically classified into two broad categories - primary and secondary. Tertiary resources are used as well, though they are less common than primary or secondary.
