They are both effectively from the same "article", drawing on data from This project to present it in a user friendly fashion. From what I can tell, for a website of a newspaper with no author, I am supposed to cite it via the first 1-3 words of the title. "Economic Diversity and...", whatever makes it clear. The problem is the distinguishing factor between the two different article "names" isn't until the end, even though the articles do have different names (as they end with "at Name of school here").
My current inclination is to treat them as you would a same author/same year and distinguish them by (2017a) and (2017b). However, my first thought was to instead refer to the articles individually, citing them as "Economic...New College". This would fit the 3 or less words and be perfectly distinct to reference them in my list, but violates the "use words from the start rule".
Should I be using one of these two options, or something else?
My actual current paper has in its citations (can't figure out the hanging tabs here, but they are in regular paper) and my citations are (Economic Diversity, 2017a), etc.
