Wikipedia's entry on citing Wikipedia says that APA formatting requires that their page on plagiarism be formatted as:

Plagiarism. (n.d.). In Wikipedia. Retrieved August 10, 2004, from

In particular, the APA format requires the article name to take the place of the author.

To cite Wikipedia with BibTeX, they say to use the code:

@misc{ wiki:###,
   author = "Wikipedia",
   title = "Plagiarism --- {W}ikipedia{,} The Free Encyclopedia",
   year = "2004",
   url = "\url{}",
   note = "[Online; accessed 22-July-2004]"

This however, puts Wikipedia as the author, among other things (and is therefore not in APA format).

The package I am using is apacite and the code I have for my bibliography is:


I have tried things like setting putting the title of the article in the author = ... field, but if I put, say, author = Estimation lemma, the output in the author position is "lemma, E." I have also tried putting quotation marks around the title, but this does not work either.

Is there any way to get around this?

Welcome to!. You can do author = "{Estimation lemma}". The extra braces are proving an extra group without sorting. I am sure we have such a question somewhere. – Marco Daniel Sep 29 '12 at 6:40

Let's have a TeX and a BIB file:



\usepackage{url,apacite}    % package url to prevent horrible linebreaks


@misc{ wiki:xxx,
  author = {{Estimation lemma}},
  title = "Estimation lemma --- {W}ikipedia{,} The Free Encyclopedia",
  year = "2010",
  url = "",
  note = "[Online; accessed 29-September-2012]"


compiled example


Notice the use of double braces: {{Estimation lemma}}.
The inner pair hides these two words from BibTeX so that it only "sees" one string.

Thank you! This is much simpler than the solution I finally came up with. After I posted this question, I toyed with the code a bit I tried inserting \hspace{4pt} between "Estimation" and "lemma". It worked, but I think this is much simpler lol – Michael Zhao Sep 29 '12 at 4:32
