Biblatex formatting for N.N. Authors

I am using biblatex with the citation style alphabetic and I have troubles with formatting a special author set-up:

If there is no author sometimes one writes N.N. (= non nominatur in Latin). I have this in my bibliography for several entries as authors (Author = {N.N.}), but formatting gives me not the necessary output.

A full example for a bibliography entry should look like:

[NN16] N.N.: Document title, 2016

But the result I get after compiling looks like:

[N.N16] N.N.: Document title, 2016

I think this is not surprising regarding the normal rules on how biblatex abbreviates authors names and surnames. But so far I failed with finding a good modification to achieve the desired format.

Does anyone have a good idea on how to solve this? Thanks for your input on this!

Here is a MWE, please note it does not contain further formatting of the citation as noted before, but is just using alphabetic:

\begin{filecontents*}{Beispielbibliographie.bib}
@Article{NN16,
Title                    = {Document title},
Author                   = {N.N.},
Year                     = {2016},
}
\end{filecontents*}

\documentclass[12pt]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[german]{babel}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{lipsum}
\usepackage[backend=bibtex, bibstyle=alphabetic, citestyle=alphabetic,
firstinits=true, isbn=false, doi=false, maxnames=4, minnames=3,
maxalphanames=3, url=false, maxbibnames=99]{biblatex}

\begin{document}

\cite{NN16}

\end{document}

• Hey Thomas, thank you for the Link, actually together with some others I also used this post to configure the bibliography. The formatting for all other authors is right, so I am thinking more of an additional formatting if author = N.N. do [NNyear] but I couldn't find the section for formatting the citation jet nor did I know, if this is the best way to proceed. – Jäger Oct 7 '16 at 22:29
• Can you provide a complete MWE because I get [NN16] like you want. – ThomasGuenet Oct 9 '16 at 10:47

With Biber I get NN16 in your example.

I'm not quite sure it is the best idea to write author = {N.N.}, if you have no author (at least use author = {{N. N.}}, or author = {{N.\,N.}},).

You can use the label field as a drop-in replacement for the letters generated from the label names

@article{NN16,
title  = {Document title},
author = {{N.\,N.}},
label  = {NN},
year   = {2016},
}


Alternatively, just add shortauthor = {NN}, for the expected output. That is because shortauthor is given preference over author when constructing the labels.

@article{NN16,
title       = {Document title},
author      = {{N.\,N.}},
shortauthor = {NN},
year        = {2016},
}

• Thanks moewe, the solution with the label works good for my cause. I didn't of more labels, than the one provided by Jabref. – Jäger Oct 10 '16 at 22:06
