# Citation is not using the custom prefix defined by multibib

I am writing a paper that I need to have two bibliographies. For example, a regular references pages and another one for a specific topic. Something like this:

I already did it with multibib.

\documentclass[sigconf]{acmart}

\usepackage[resetlabels,labeled]{multibib}
%...
\newcites{New}{The other list}
\begin{document}
%...

\section{test}
\citep{GM05} this is a test \citeNew{Williams2009}
% and this as well \citeNew{Gren}

\bibliographystyle{ACM-Reference-Format}
\bibliography{sample-bibliography}

\bibliographystyleNew{plain}
\bibliographyNew{references}

\end{document}


-- Content of my reference.bib file

@article{Williams2009,
author = {Williams, Laurie and Kudrjavets, Gunnar and Nagappan, Nachiappan},
doi = {10.1109/ISSRE.2009.32},
isbn = {9780769538785},
title = {{On the Effectiveness of Unit Test Automation at Microsoft 1}},
year = {2009}
}

@article{Gren,
author = {Gren, Lucas and Antinyan, Vard},
title = {{On the Relation Between Unit Testing and Code Quality}}
}


-- Content of my sample-bibliography.bib file

@article{GM05,
author = {Williams, Laurie and Kudrjavets, Gunnar and Nagappan, Nachiappan},
doi = {10.1109/ISSRE.2009.32},
isbn = {9780769538785},
title = {{Example}},
year = {2009}
}


However, the citation is not correct. I want it to be "[1] this is a test [New1]", instead of "[1] this is a test [1]"

• I am working with the following template overleaf.com/latex/templates/… – Karla Silva Jul 8 '17 at 18:40
• Welcome to TeX.SX! External templates can change. Please try to make a minimal but working example with bibliography (MWEB) and add it into your question. This would help us to reproduce the problem, test our suggestions and find an answer. – Schweinebacke Jul 8 '17 at 18:48
• @Schweinebacke, I updated my question! thanks a lot :) – Karla Silva Jul 8 '17 at 19:40
• Please always test your example. The ... in the document preamble result in an error message. Working means, that the example should be compilable without error message or with only those error messages that are part of the problem. I've commented the line in your example to get a real MWEB. – Schweinebacke Jul 9 '17 at 6:47

It looks like the problem is not with acmart, but rather with natbib. Here is your example with article:

%\documentclass[sigconf]{acmart}
\documentclass{article}
\usepackage{natbib,url}
\setcitestyle{numbers,square}
\usepackage[resetlabels,labeled]{multibib}
%...
\newcites{New}{The other list}
\begin{document}
%...

\section{test}
\citep{GM05} this is a test \citeNew{Williams2009}
% and this as well \citeNew{Gren}

\bibliographystyle{plainnat}
\bibliography{sample-bibliography}

\bibliographystyleNew{plainnat}
\bibliographyNew{references}


As a workaround, I would use consecutive numbering instead:

\documentclass[sigconf]{acmart}
\usepackage{multibib}
%...
\newcites{New}{The other list}
\begin{document}
%...

\section{test}
\citep{GM05} this is a test \citeNew{Williams2009}
% and this as well \citeNew{Gren}

\bibliographystyle{ACM-Reference-Format}
\bibliography{sample-bibliography}

\bibliographystyleNew{ACM-Reference-Format}
\bibliographyNew{references}

\end{document}


• Thanks, after two days I finally found a decent solution without any hacks or something like that! – leandroungari Jul 2 at 18:13
