I am doing my masters in energy systems engineering. Whenever I cite a scientific paper that I found online, I include the link where I got it and date accessed in the citation, as well as the DOI, and publisher.
I was discussing this with a classmate, since he just cites the article without including a link, just the journal name, and volume, as well as providing the DOI.
I was wondering what was the correct way to cite an online scientific paper. We are often asked to cite in IEEE format.
