# Natbib: How to suppress the same author in case of multiple citations?

My problem is simple. In my document, in order to produce references, I use natbib. When I have the same author I prefer to have hers/his name to appear once (in the beginning) and then instead of his full name I want to have a 3-em baseline.

Is this possible to happen?

Here is a simple code:

\usepackage{ucs}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{makeidx}
\usepackage{graphicx}
\usepackage[left=1.00in, right=1.00in, top=1.00in, bottom=1.00in]{geometry}
\usepackage[sectionbib, sort]{natbib}

\author{My name}
\title{Suppressing same author's name in multiple citations}

\begin{document}
\maketitle

As it is mentioned in \cite{Card2005} and \cite{Card2012} ...

\bibliographystyle{chicagoa}
\bibliography{biblio}
\end{document}

where the bibliography file (biblio.bib) contains:

@ARTICLE{Card2005,
author = {Card, David},
title = {{Is the New Immigration Really so Bad?}},
journal = {Economic Journal},
year = {2005},
volume = {115},
pages = {F300--F323},
number = {507},
month = {November},
timestamp = {2013.06.19}
}

@ARTICLE{Card2012,
author = {Card, David},
title = {{Comment: The Elusive Search for Negative Wage Impacts of Immigration}},
journal = {Journal of the European Economic Association},
year = {2012},
volume = {10},
pages = {211--215},
number = {1},
timestamp = {2013.06.25}
}

If you are willing to switch to biblatex this is easy; and, for what it is worth, chicagoa dates from 1992 (and was designed for LaTeX 2.09!) and therefore implements the 13th edition Chicago Manual of Style, which was published in 1982 (14th = 1993; current is 16th). biblatex has an up-to-date contributed 'Chicago' style, called biblatex-chicago. – jon Sep 25 '13 at 4:14
This seems to be possible with natbib, have a look at American Naturalist BibTeX BST style file (amnatnat.bst) and The McBride bibliography style (mcbridge.bst). However biblatex offers a wider range of trackers and options. – moewe Sep 25 '13 at 4:55
@jon How the code above can be used with biblatex and get the result that I want. Also, I have a specific bibliography style that I have manually installed in the MikTex system. Is the declaration of bibliography style the same as in Natbib? – Pantelis Kazakis Sep 25 '13 at 16:40
@PantelisKazakis What to do to switch to biblatex? and biblatex for idiots might give you a quick overview of how biblatex works. Custom .bst cannot be used with biblatex, but it is very easy to modify one of the existing styles to your needs, see for example Guidelines for Customizing biblatex styles. Though the manual is quite daunting, biblatex is quite easy to use. – moewe Sep 25 '13 at 21:07
@moewe It seems that I need to learn everything from the very beginning. Maybe I will do that later, but for now, I will continue using natbib, for it fits much better my needs (it has hypperrefs, coloured citations) and with the assistance of some other codes that I have found in the forum it is quite good. I know biblatex is the future, and I will devote sometime in the future. – Pantelis Kazakis Sep 25 '13 at 21:41

As @jon has pointed out in the comments above chicagoa is quite an old implementation of the Chicago Manual of Style guidelines way back from 1992.

For biblatex there is biblatex-chicago, it implements the 16th edition of the CMS and is still actively maintained.

biblatex-chicago replaces recurring author names by a dash.

A short example of a file using biblatex-chicago would be

\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[authordate]{biblatex-chicago}

\begin{document}
\cite{cicero, wilde, baez/online, baez/article}
\printbibliography
\end{document}

Where biblatex-examples.bib is a file containing the bibliography. As a matter of fact that particular file is part of the standard biblatex installation. Normally you would put yourbibfile.bib right in the same directory as the main .tex file.

For current versions of biblatex, running Biber instead of BibTeX is recommended. So you would compile the above example via

pdflatex test
biber test
pdflatex test
pdflatex test

The output should then look like this
