As many of those who have read academic papers know, even claims with citations are often suspicious. Time and time again I've found cited sources that don't say what was claimed. Sometimes, citations are not specific enough (e.g., citing a huge book rather than the specific page with the evidence). So, better than giving a URL would be to give a URL with a "fragment" if possible, i.e., #id. https://en.wikipedia.org/…
its nice to have urls, but I think we all know deep down they wont change much in the grand scheme of things. I know when I see a quote on the internet, its almost assuredly fake, but if I am interested I can always just google it.
