# Doesn't write the full last name of third author

I have some trouble with my literature directory. It doesn't show the full name of the third author. It only shows:

Hairer, E. und Lubich, C. u. W. G.

But I want to see:

Hairer, E., Lubich, C. und Wanner, G.

My code looks like following:

\documentclass[a4paper,12pt]{article}
\bibliographystyle{chicago}
\begin{document}
\bibliography{BIB}
\end{document}


And in my Bib the code is

@book{hairer2002geometric,
title={Geometric Numerical Integration: Structure-Preserving Algorithms for Ordinary Differential Equations},
author={Hairer, E., Lubich, C. und Wanner, G.},
series={Springer Series in Computational Mathematics},
year={2002},
volume={31},
publisher={Springer},
}

author={Hairer, E. and Lubich, C. and Wanner, G.} is the correct syntax –  egreg Dec 13 '13 at 14:20
Thank you for you answer. I write it in German, that's why I need 'und' between the authors. How can I change the and to 'und'? –  little_miss_sunshine Dec 13 '13 at 14:25
@little_miss_sunshine The BibTeX database format requires and between entries in the input: this is nothing to do with what gets printed for 'and' in the output. –  Joseph Wright Dec 13 '13 at 14:47

How can I change the 'and' to 'und'?

If you want to stick with BibTeX and the chicago bibliography style, while also getting the conjunction between authors to print as "und" rather than as "and", you may want to proceed as follows:

• Locate the file chicago.bst in your TeX distribution. Make a copy of this file and name it, say, mychicago.bst. (Don't edit an original file directly.)

• Open mychicago.bst in your favorite text editor. (The editor you use to edit your .tex files will do fine.)

• Find and replace all five [5] instances of " and " with, you guessed it, " und ".

• Save the file mychicago.bst, either in the directory where your main .tex file is located or in a directory that's searched by TeX/BibTeX. If you choose the latter option, you will probably need to update TeX's filename database.

• Start using the newly created bibliography style by issuing the command \bibliographystyle{mychicago}. The first time you use a new bibliography style, it's usually a good idea to blow away all temporary and auxiliary files and then run LaTeX, BibTeX, and LaTeX twice more to fully synchronize all cross-references.

As others have already pointed out, and is a BibTeX keyword that's used to separate the authors in an author field. Thus, be sure to write either

author={Hairer, E. and Lubich, C. and Wanner, G.}


or

author={E. Hairer and C. Lubich and G. Wanner}


With these modifications to mychicago.bst in place, this is what you'd get from the entry in question:

Note that "Chicago" style inverts the surname and first name's initial only for the first author; subsequent authors' names are set as First-name-initial. Surname.

sounds perfect. but I can't find chicago.bst. The only thing I have with chicago are:chicago.tmp, biblatex-chicago.tmp. –  little_miss_sunshine Dec 13 '13 at 18:50
@little_miss_sunshine -- If you open a terminal (aka command line) window and type kpsewhich chicago.bst and hit return, what answer do you get? If all else fails, you could download it from the CTAN. –  Mico Dec 13 '13 at 18:59
it even finds something.it says 'C:/users/.../Roaming/Miktex/2.9/... But if I open C/users/... there is no folder Roaming. –  little_miss_sunshine Dec 14 '13 at 12:41
I found it. It was in an hidden folder. –  little_miss_sunshine Dec 14 '13 at 13:00
It works with the 'und' now. Thank you sooooo much. –  little_miss_sunshine Dec 14 '13 at 13:03

With that BibTeX entry you get many errors:

Too many commas in name 1 of "Hairer, E., Lubich, C. und Wanner, G." for entry hairer2002geometric
while executing---line 1563 of file chicago.bst


and this is repeated 20 times.

The correct syntax is

author={Hairer, E. and Lubich, C. and Wanner, G.}


Authors should be separated by the keyword and; each author is Surname, Name or Name Surname (the first format is usually preferred).

I suggest you to switch to biblatex:

\begin{filecontents*}{\jobname.bib}
@book{hairer2002geometric,
title={Geometric Numerical Integration:
Structure-Preserving Algorithms
for Ordinary Differential Equations},
author={Hairer, E. and Lubich, C. and Wanner, G.},
series={Springer Series in Computational Mathematics},
year={2002},
volume={31},
publisher={Springer},
}
\end{filecontents*}

\documentclass[a4paper,12pt]{article}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage{biblatex}

\begin{document}
\nocite{*}
\printbibliography
\end{document}


The usage of filecontents* is just for making the example selfcontained. In the argument to \addbibresource you should insert the actual name of your BibTeX database (ending with .bib).

Many customizations are possible.

The comment \printbibliography doesn't work. If I use it like your code, then the literature directory doesn't show upt at all. –  little_miss_sunshine Dec 13 '13 at 15:04
@little_miss_sunshine You have to use Biber rather than BibTeX –  egreg Dec 13 '13 at 15:08
