= How to reference a book in Wikipedia markup?
Their reference markup is incredibly overengineered, convoluted, and underdocumented, it is unbelivable!
Use the reference:
``
This is a fact.{{sfn|Schweber|1994|p=487}}
``
Define the reference:
``
===Sources===
{{refbegin|2|indent=yes}}
*{{Cite book|author-link=Silvan S. Schweber |title=QED and the Men Who Made It: Dyson, Feynman, Schwinger, and Tomonaga|last=Schweber|first=Silvan S.|location=Princeton|publisher=University Press|year=1994 |isbn=978-0-691-03327-3 |url=https://archive.org/details/qedmenwhomadeitd0000schw/page/492 |url-access=registration}}
{{refend}}

`sfn` is magic and matches the the author last name and date from the `Cite`, it is documented at: https://en.wikipedia.org/wiki/Template:Sfn
Unforutunately, if there are multiple duplicate `Cite`s inline in the article, it will complain that there are multiple definitions, and you have to first factor out the article by replacing all those existing `Cite` with `sfn`, and keeping just one `Cite` at the bottom. What a pain...
You can also link to a specific page of the book, e.g. if it is a book is on <Internet Archive Open Library> with:
``
{{sfn|Murray|1997|p=[https://archive.org/details/supermenstory00murr/page/86 86]}}
``
For multiple pages should use `pp=` instead of `p=`. Does not seem to make much difference on the rendered output besides showing `p.` vs `pp.`, but so be it:
``
{{sfn|Murray|1997|pp=[https://archive.org/details/supermenstory00murr/page/86 86-87]}}
