I have come across a few infamous newspaper articles and I'd like to cite them to support some of my ideas and to take a few thoughts from them. However, I cannot seem to distinguish whether such articles are primary or secondary. What worsens things further is the fact that the authors do not cite their words and, usually, reference lists do not exist.
Do I treat a newspaper article like a primary source and cite it as such? If not, how can I track back the information given the fact that there are no references?
