Bibliografia multilíngue com estilo nome-ano

Question

Gostaria de escrever um texto grego com referências tanto em inglês quanto em grego e gostaria de compilá-lo com pdfLatex. Eu tentei usar o seguinte código:

\documentclass{article}

\usepackage{ucs}
\usepackage[utf8x]{inputenc}
\usepackage[greek,english]{babel}
\newcommand{\en}{\selectlanguage{english}}
\newcommand{\gr}{\selectlanguage{greek}}
\usepackage[round]{natbib}

\begin{document} 
\gr 
Όπως έχει αναφερθεί στην Ελληνική \citep{Sfa04}
αλλά και τη διεθνή \citep{Miranda02} βιβλιογραφία 

\bibliographystyle{plainnat}
\bibliography{test} 


\end{document}

E o arquivo test.bib é:

@book{Miranda02,
 language = {english},
 author = {M. J. Miranda and P. L. Fackler},
 publisher = {MIT Press},
 title = {Applied Computational Economics and Finance},
 year = {2002}
}

@book{Sfa04,
 language = {greek},
 author = {Μ. Σφακιανάκης},
 publisher = {Εκδόσεις Πατάκη},
 title = {Προσομοίωση και εφαρμογές},
 year = {2004}
}

E funciona perfeitamente. Meu problema é que gostaria de ter citações como (Nome do autor, ano) e referências em inglês e grego.

Answer 1

Use biblatex + biber. Possui excelente suporte para vários idiomas. Você terá que definir o idioma no babador com o campo langid:

@book{Miranda02,
 language = {english},
 langid = {english},
 author = {M. J. Miranda and P. L. Fackler},
 publisher = {MIT Press},
 title = {Applied Computational Economics and Finance},
 year = {2002}
}

@book{Sfa04,
 language = {greek},
 langid={greek},
 author = {Μ. Σφακιανάκης},
 publisher = {Εκδόσεις Πατάκη},
 title = {Προσομοίωση και εφαρμογές},
 year = {2004}
}

Então isso funcionará:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage[autostyle]{csquotes}
\newcommand{\en}{\selectlanguage{english}}
\newcommand{\gr}{\selectlanguage{greek}}
\usepackage[style=authoryear,natbib,autolang=other,language=auto]{biblatex}
\addbibresource{test.bib}

\begin{document}
\gr
Όπως έχει αναφερθεί στην Ελληνική \citep{Sfa04}
αλλά και τη διεθνή \citep{Miranda02} βιβλιογραφία

\printbibliography
\end{document}
