Hello, I'm DVdm. I noticed that you added or changed content in an article, Gottfried Wilhelm Leibniz, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page.   DVdm (talk) 12:24, 2 October 2021 (UTC)
