Tips 
 * Don't be afraid to edit! Just find something that can be improved and make it better. Other editors will help fix any mistakes you make.
 * It's normal to feel a little overwhelmed, but don't worry if you don't understand everything at first—it's fine to edit using common sense.
 * If an edit you make is reverted, you can discuss the issue at the article's talk page. Be civil, and don't restore the edit unless there is consensus.
 * Always use edit summaries to explain your changes.
 * When adding new content to an article, always include a citation to a reliable source.
 * If you wish to edit about a subject with which you are affiliated, read our conflict of interest guide and disclose your connection.
 * Have fun! Your presence in the Wikipedia community is welcome.

Citations at Externality
I almost reverted your edit to Externality (and another editor may still do so), because you made two substantial contributions without supporting it with any citations. It is not sufficient to list two books or papers at the end of the article. At each paragraph, you need to give the source that supports that paragraph, in sufficient detail that someone reading the article can easily verify it. In a book, that means providing at least the chapter and preferably the page. A journal paper does not generally need further elaboration unless it is long enough to have well-defined sections.

If you plan to contribute more extensively to wikipedia, you should read citing sources. Ideally, you would emulate this citation: but nobody expects you do reach that standard in your first edits. In the meantime, please try to rectify the omission at externalities using the simplest form of citation and another editor will format it properly. The technique is to enclose the citation in "ref" tags, thus. So for the Pieper citation above, it would be sufficient to append something like

I hope that this is clear but if not, please ask at the Teahouse where the volunteers there are more experienced at giving explanations than I am. --𝕁𝕄𝔽 (talk) 09:57, 24 April 2023 (UTC)
