This is a really well developed topic - I just wanted to make a technical note regarding how you have arranged your end references. I noticed that you are often repeating sources as multiple entries - if you are use the "additional use of same source" earlier with the names you set for each source, your end references will compile each instance of the same source as sub numbers (ex. 2.1, 2.2, 2.3, etc...). This would help the reader identify what sources are being cited multiple times, and also help your bibliography be condensed to show only one instance of each source. Your content was an excellent read, and I really like how you have arranged your headings and sub-headings to make the article flow nicely!
