We've previously covered citations on Wikipedia and their role in verifying accurate information, but it's worth talking a bit about where you can find them: reference sections.

These are found at the bottom of a Wikipedia entry, collecting all of the (properly formatted) citations for a given article. Interestly, if you open one up by clicking "edit source" you won't find much: often just a bit of code like {(reflist)}.

This is because all reference formatting occurs in-line, which is to say, the code that generates these citations can be found throughout the text, where the superscript numbers appear.

In recent years, Wikipedia has made it easier to see this information without visiting the page footer: in many cases you can hover or tap on the number to see the details. And the Visual Editor can make it much easier to create them.
