# Using acronyms for institutions in citations messes up sorting in the bibliography when using "author-year"

I would like to abbreviate "European Commission" by "EC", also when citing a document of the EC. The problem is that the abbreviation will only be introduced when I write "\ac{EC}" (using the acronym package) in the text but not when I cite a document of the EC.

I have tried to work around this problem by writing "\ac{EC}" in the author field of my bibliography file. This works fine, except that the sorting in the references section gets messed up when using "author-year", because "\ac{EC}" is recognized as starting with an "a".

\documentclass{article}
\usepackage[printonlyused]{acronym}
\usepackage[backend=bibtex,
natbib=true,
style=authoryear,
firstinits=true,
uniquename=init,
isbn=false,
doi=true,
url=true,
clearlang=true,
dashed=false
]{biblatex}
\acrodef{EC}{European Commission}

\begin{document}
\citet{Baltensperger2015} \\
\citet{EuropeanCommission2013a}\\
\citet{EuropeanCommission2013}

\printbibliography

\end{document}


The reference section then starts with the "EC" citations instead of the "Baltensperger" one.

Any ideas how I could use abbreviations in this way and get the sorting right?

• Try sortname={EC} or sortname={European Commission}. If that doesn't work a full MWE with the .bib entry in question would be appreciated. Dec 14 '15 at 11:28
• Thanks, this works! Mendeley doesn't support such a field though, so fighting on a new front now.. Dec 14 '15 at 12:21
• Mhhh, ask the Mendeley guys to support it. It is really the most elegant solution to this problem. I can only think of a different solution that would need Biber and not BibTeX as backend. (But when I use Biber, everything seems to work fine anyway.) Would Biber be an option for you? Dec 14 '15 at 12:47
• I'm really wrapping up my stuff here, so there is no point in switching for me. And Mendeley ... there are tons of requests like these and all I've seen from them in the last years were some cosmetic updates. I wouldn't recommend the software because the dev team is really disconnected from the community, but since I've started with it it's too late to change now. My solution is to write "EC" in the "translators" field, which I never use, and then find&replace it by "sortname" in the generated bib-file. Dec 14 '15 at 13:07
• Sorry to hear that. I'm always very wary of the automatic export features, sometimes they get things wrong and sometimes they don't support all features. Still, I have written up a solution that mentions sortname and the fact that Biber gets it right. Dec 14 '15 at 13:12

You can use the sortname field to specify the name used for sorting, so you would probably go for

sortname={EC}


or

sortname={European Commission}


If you use Biber the sorting is correct automatically, because the \ac is ignored when the sort order is determined.

For BibTeX there is the old \noopsort trick (see the UK TeX FAQ)

@PREAMBLE{ {\providecommand{\noopsort}[1]{}} }


and

author = {{\noopsort{EC}}{\ac{EC}}}

• sortname isn't recognized by \documentclass{elsarticle}. Any ideas how the sorting could be done in that case? Dec 16 '15 at 9:32
• @Tobias That is not something that depends on the document class as such, but on the bibliography package used. With biblatex the field sortname will always be recognised. But if you use a .bst file that probably won't work. Dec 16 '15 at 9:34
• @Tobias If the question is about BibTeX now, have a look at tex.ac.uk/FAQ-bibprefixsort.html and if that doesn't help ask a new question. Dec 16 '15 at 9:36
• Based on your comment, I found the following solution which works with biblatex and elsarticle and Mendeley! Just define the "author" in Mendeley as "{\noopsort{EC}}{\ac{EC}}" and add \providecommand{\noopsort}[1]{} to your preamble. Thanks moewe -> Credit should go to you, so please update your answer.

• @Tobias I have added a short passage about the \noopsort trick. Dec 16 '15 at 10:30
