Authors of scholarly articles are usually subject experts, researchers or scholars in their fields. Scholarly journals often list the author's credentials near the beginning of each article. If no specific credentials are present, such as degrees or other publications, the author of a scholarly article will likely associate with an institution of higher education. Scholarly articles often start with an abstract of the contents of the article. The citation will not give you a clue as to the presence of an abstract, you must examine a copy of the journal.
Scholarly articles are generally longer than articles in a popular magazine.
The range of page numbers in the article citation will give you this information. The language used in scholarly articles draws heavily upon terminology, jargon and definitions of the subject discipline. It assumes some degree of subject knowledge on the part of the reader. Therefore, the reading of scholarly articles may be difficult for newcomers to the discipline. As you can see from these examples, the name of the professional organization may or may not appear as part of the title.
