While newspapers are not considered scholarly sources, they are frequently looked at as primary sources if the person writing the article was present at the event being described. (Confirm this with your professor.) They are also a useful means of obtaining names of leaders, activists, and military officers who might be involved in the subject you are researching. Newspapers are also a great source for editorials.
The coverage of each newspaper varies by database so it is necessary to check closely to be sure the desired title and date will be available in the selected database.
