switch to source editing, and find the reference you want to use again.
After the word ref make a gap and add the word name along witn an = sign.
So that it looks like this ref name=.
After the equals sign, give the reference a name (preferably related to the subject) in quotation marks, along with a gap and a / symbol after the reference name, for example:
ref name="Football" /
Then all you have to do is copy all the stuff between the...
< and the...
> symbols...
In my example "all the stuff" is ref name="Football" /
Then paste it next to the information you want to reference.
"Football" as the name for a reference used more than once, then one instance (conventionally but not necessarily the first) should be <ref name="Football">[all the details of author(s), title, access date, etc, here]</ref>, and each of the others should be the much simpler <ref name="Football" />. (Incidentally, the name "Football" will only be visible to people editing the article.) The full-details instance may use one of the "cite" templates (e.g. Template:Cite web), but it doesn't have to do so.
^Cite error: The named reference Football was invoked but never defined (see the help page).
