that was a sales site. As you can see, I found a scholarly book to source part of the sentence. You might want to look at Help:Referencing for beginners, a page I still look at for reminders from time to time. It takes experience to recognise good sources, but for articles such as this one they should usually be academic books or journals. Doug Wellertalk 10:16, 6 May 2020 (UTC)[reply]
