# Automate ordering of citation within parenthesis

I use the biblatex-chicago package and would like to automatically sort citation within parenthesis by order in the bibliography. Basically, I would like to do what \usepackage[sort]{natbib}* does, but in biblatex.

If I type \citep{Smith2009,Smith2001,Jones2010,Jones1999} I want the results to look like (Jones,1999,2010;Smith,2001,2009).

    \documentclass{article}
\RequirePackage[natbib, authordate,backend=biber,doi=false,isbn=false,url=false,
ibidtracker=false]{biblatex-chicago}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book{Jones1999,
author = {Jones, A.},
year = {1999},
title = {Title},
publisher = {Publisher},
}
@book{Jones2010,
author = {Jones, A.},
year = {2010},
title = {Title},
publisher = {Publisher},
}
@book{Smith2001,
author = {Smith, A.},
year = {2001},
title = {Title},
publisher = {Publisher},
}
@book{Smith2009,
author = {Smith, A.},
year = {2009},
title = {Title},
publisher = {Publisher},
}
\end{filecontents}

\begin{document}

\citep{Smith2009,Smith2001,Jones2010,Jones1999}

\printbibliography

\end{document}

• I didn't see a point of adding a MWE because I have exactly the same question as in the link I referred to. Upon re-reading I was indeed unclear. My apologies. Feb 1 '18 at 16:35
