# Text is english, citation style is in another language

My LaTeX document is English but when I cite multiple authors

Teyseyre und Campo

Teyseyre and Campo

I set `\selectlanguage{english}` and for every single entry I added `language = {english}`.

I also tried adding the following which I found in another thread:

``````\usepackage{babelbib}
\selectbiblanguage{english}

\renewcommand\betweenauthors{and}
\providecommand\harvardand{}
\renewcommand\harvardand{and}
``````

Tt still displays the German "und". Can someone help me getting rid of it?

• Do you use BibLaTeX? If you do, `\usepackage[english]{babel}` fixes your issue. – ppr Oct 30 '13 at 18:51
• I do use \usepackage[english]{babel} and natbib – keinabel Oct 30 '13 at 19:05
• `natbib` is not a 'style': what argument are you giving `\bibliographystyle`? – jon Oct 30 '13 at 19:16
• You should consider change from natbib to biblatex. Biblatex has a better language support and is more flexible. To achieve what you want with biblatex you need only the babel line, the .bib call `\bibliography{file.bib}` and `\usepackage[style=authoryear-comp]{biblatex}` (or whatever style you want. – ppr Oct 30 '13 at 19:19
• @jon I use natdin then – keinabel Oct 30 '13 at 19:21

The bibliography style `natdin` lets users cite and reference pieces according to the German standard "DIN 1505, Parts 2 and 3" (citing from the header of `natdin.bst`). As such, it shouldn't come as a surprise that you get the German connector particle "und" rather than, say, "and". Changing parameters such as `\harvardand` will have no effect whatsoever since the `natdin` bibliography style doesn't use that macro.

Assuming you want to stick with `natdin` as your bibliography style and all you want to do is change the connector particle from "und" to "and", you could proceed as follows:

• Find the file `natdin.bst` on your computer and make a copy, to be called, say, `mynatdin.bst`. (Never edit an original file that's part of the TeX distribution directly.)

• Open `mynatdin.bst` in your favorite text editor and search for the BibTeX function named `und`. (It's on line 181 in my copy of this file.) Given your description, this function is probably set up as

``````FUNCTION { und } { " und " }
``````

Change it to

``````FUNCTION { und } { " and " }
``````
• Next, search for the function `ua.etal` (probably just a few lines up from the `und` function). Change it so that it says

``````FUNCTION { ua.etal } { " et~al." }
``````
• Save the file `mynatdin.bst`, either in the directory where your main tex file is located or in a directory that's searched by your TeX distribution. If you choose the latter option, you will probably also need to update/refresh the TeX filename database in an appropriate way.

• Start using the new bibliography style my issuing the command

``````\bibliographystyle{mynatdin}
``````

in your main tex file. Be sure run LaTeX, BibTeX, and LaTeX twice more to fully update the work of BibTeX and LaTeX.
