Bibliography style: author format

I would like the item in my bibliography to be format like this

Cauchy, L. A., Goursat E., Contour integral. French Academy, 2012.


That is:
-no numbering or key before the authors name
-lastname before the firstname where the firstname is abbreviate

But I get this

with the below sample document which illustrates the different kind of author entries I can have.

Should I manually format all author entries to get the format I want?
Is there an automated way to get this result?

\documentclass{article}
\usepackage{filecontents}

\begin{filecontents*}{example.bib}

@article{
refOne,
author = {Cauchy, L. A. and E. Goursat },
title = {Contour integral},
year = {2012},
}

@article{
refTwo,
author = {Louis Augustin Cauchy and Edouard Goursat},
title = {Contour integral},
year = {2012},
}

@article{
refThree,
author = {L. A. Cauchy and E. Goursat},
title = {Contour integral},
year = {2012},
}

\end{filecontents*}

\begin{document}
\bibliography{example}{}
\bibliographystyle{plain}
\nocite{*}
\end{document}

I recommend the package biblatex. I think the style authoryear is a good starting point. However there are a lot of styles available. –  Marco Daniel Aug 7 '12 at 19:15

    \usepackage[round, sort&compress, authoryear]{natbib}


and near the end of document

    \bibliographystyle{agsm}
\bibliography{example}  % example.bib


This should have no numbers in the references included.

You can just give first and last names, and the authors should be fine. –  Dualinity Aug 7 '12 at 15:53
I try your suggestion, but I get natbib error: bibliography not compatible with author-year citations. Should the author name be written in a certain format? –  Nicolas Essis-Breton Aug 7 '12 at 22:49
Fortunately, there's actually no need to embark on this rather tedious path. I would recommend that you run the file makebst.tex through LaTeX. (At a command prompt, type "latex makebst" and follow the prompts.) This utility (created by the author of the natbib package) poses lots of detailed questions regarding how you want various items formatted, and at the end of the process it creates a brand-new bibliography style (with extension .bst) that is tailored to your exact needs.
