# How to cite it properly?

What is the correct way to cite the following:

Should there be a comma after see also? And what is the command to produce it?

-
As @Alex said, and the whole aside not inside the first ref: [2] and the references therein (see also [13,15,33]). But alas, I cannot claim any authority on this issue other than gut feeling (my gut can be quite assertive sometimes). –  Harald Hanche-Olsen Sep 6 '12 at 10:07
[2, and the references therein] conventionally refers to the study [2] and in it the Section, Chapter, or Theorem etc. which is called and the references therein. –  percusse Sep 6 '12 at 10:58

The package natbib redefines the \citecommand with optional arguments that do exactly what you are asking for. Here is an example:

\documentclass{article}

\usepackage{filecontents}
\usepackage[numbers]{natbib}

\begin{filecontents}{biblio.bib}
@article{Author2012,
Author = {Author, A},
Title = {Article},
Year = {2012}}
\end{filecontents}

\begin{document}

\cite{Author2012}

\cite[e.g.]{Author2012}

\cite[see][]{Author2012}

\cite[and references therein]{Author2012}

\cite[see][and references therein]{Author2012}

\bibliographystyle{plainnat}
\bibliography{biblio}

\end{document}

The output looks like this:

If you prefer author-year citation style, you can remove the [numbers] option when loading the package, and you can replace the square brackets by round brackets with the option [round].

-
Some of that is also possible without natbib: \cite[Ch.~1]{Author2012} gives [1, Ch. 1] and \cite[p.~387]{Author2012} gives [1, p. 387]. Any words not relating to the citation should be kept outside the square brackets, see @percusse's comment above. –  Alex Sep 6 '12 at 12:36
