# Spanish and english bibliography references in the same document using \bibliographystyle{dcu}

I've written a latex document with bibliography references in spanish and english. I wanted to know if there is way to cite in both languages. I mean, I wanted cites like:

"Author1 and Author2 (year1)" and

"Author3 y Author4 (year2)"

in the same document.

The code below show what I've done, it just produces references in english.

\usepackage[spanish]{babel}
\usepackage{natbib}
...
\begin{document}
...
...
...

%-----------------------------------
%   BIBLIOGRAPHY
%-----------------------------------

\label{Bibliography}
\bibliographystyle{dcu} % Use the "dcu" BibTeX style for formatting the Bibliography
\nocite*{}
\bibliography{Bibliography.bib} % The references (bibliography) information are stored in the file named "Bibliography.bib"

\end{document}

• Welcome to TeX.SX! I'm not sure if bibtexwith natbib let you achieve what you request easily, but biblatexcan do it. Since you use babelyou can do it easily: Now, my doubt is if you want to cite the same reference twice: once in Spanish and the other in English or simply cite references in Spanish or English. – Aradnix Sep 30 '14 at 22:03
• Hi Aradnix, I wanted to cite once per language. Do you have any suggestion? – Uzg Sep 30 '14 at 22:19
• Well, my suggestion is move to biblatex. You can use aliases for the bibtex and natbib options and use the babel language options for cite correctly in both languages. – Aradnix Sep 30 '14 at 23:18

The template is obsolete. An updated version can be found on latextemplates.com. It uses the new features of package biblatex, where it is very easy to do what you want.
