Replacing “and” by “og” and “In”by “I” in references and bibliograpy using natbib

Since I am writing in norwegian, I would like to chang the two words "and" and "in" into norwegian. "And" appears both in references in the text and in the bibliography, while "in" appears in the bibliography.

My document:

\documentclass[a4paper, norsk, 12pt]{article}
\usepackage[latin1]{inputenc}
\usepackage [norsk] {babel}
\usepackage[round, longnamesfirst]{natbib}

\begin{document}

If I have more than one author, the reference would be a list of alle the authors the first time i cite it \citep{fysdid}.
The problem is that I can not have the word ''and'' in the reference when I am writing i norwegian. I would like to replace it by ''og''.

\renewcommand{\refname}{Litteratur}
\bibliography{litteratur}
\bibliographystyle{abbrvnat}

\end{document}


the bibtex-file:

@book{fysdid,
title= {Fysikkdidaktikk},
author= {Carl Angell and Berit Bungum and Ellen K. Henriksen and Stein Dankert Kolstø and Jonas Persson and Reidun Renstrøm},
year= {2011},
publisher={Manusutkast},
}


The result:

If I have more than one author, the reference would be a list of alle the
authors the rst time i cite it (Angell, Bungum, Henriksen, Kolst, Persson,
and Renstrm, 2011). The problem is that I can not have the word "and"
in the reference when I am writing i norwegian. I would like to replace it by
"og".

Did you tried the babel package with your language? It might be best to add a minimal working example (MWE) which shows what you have so far. – Martin Scharrer May 12 '11 at 9:58

You can create a Norwegian compatible BibTeX style with makebst, but there's an easier way. Make a copy of abbrvnat.bst calling it abbrvnat-no.bst. In this file do a search of the strings " and " and change them into " og "; something similar must be done with in, I presume. Then call this new style with the \bibliographystyle command.

The new style should be put in a place known to the TeX system, which can be the working directory. If you need also in other projects you should consult the documentation of your TeX distribution in order to find the right place and the necessary steps to make it known.

Jeg synes at det er også nødvendig å endre "In " til "I ". (For å være komplett, skulle ord som "Volume" også endres). Med disse tre endringene, fant jeg 13 ord som skulle endres. Filen er ganske lang (for lang for å inkluderer som et svar) men endringene skje på linjer 121, 232, 325, 475, 597, 598, 641, 644, 652, 688, 691, 694, 1111. (Ellers send meg en e-post og jeg kan sende filen.) – Loop Space May 12 '11 at 12:34
@Andrew: Well, I couldn't say it better. :) – egreg May 12 '11 at 15:32
Sorry ... couldn't resist. – Loop Space May 12 '11 at 18:05
Thanks, this was really helpful! I had to change not only "I", "and" and "volume", but also "pages", "Technical Report", etc. – user10723 Jan 12 '12 at 15:00
@PESolberg Instead of posting a “Thank you” as an additional answer, you should thank egreg by upvoting his answer (with the upward pointing arrow to the left of it; you need 15 reputation points before you can upvote). We want to keep the answer space reserved for actual answers, that's why I converted the non-answer to a comment. – Stefan Kottwitz Jan 12 '12 at 15:16
