# Replace "dot" with "comma" using biber and verbose-trad1

I'd like to have a "comma" instead of a "dot" after the authors and before the title. In other words, replace the "dot" for a "comma" as the author-title separator...

MWE :

\documentclass{article}
\usepackage[french]{babel}
\usepackage{csquotes}

\begin{filecontents}{jobname.bib}
@Book{clone,
author = {Maniatis, T. and Fritsch, E. F. and Sambrook, J.},
title = {Molecular Cloning: A Laboratory Manual},
year = {2001},
publisher = {Cold Spring Harbor Laboratory},
location = {New York},
edition = {3}}
\end{filecontents}

\begin{document}
This is just a test\footcite{clone}
\end{document}


Here you are:

\documentclass{article}
\usepackage[french]{babel}
\usepackage{csquotes}

\usepackage{xpatch}
\xpatchbibdriver{book}{%
\newunit\newblock
\printfield{edition}%
}
{%
\printfield{edition}%
}{}{}

\begin{filecontents}{jobname.bib}
@Book{clone,
author = {Maniatis, T. and Fritsch, E. F. and Sambrook, J.},
title = {Molecular Cloning: A Laboratory Manual},
year = {2001},
publisher = {Cold Spring Harbor Laboratory},
location = {New York},
edition = {3}}
\end{filecontents}


• I was referring to the fact that the command \labelnamepunct could eventually change something else, but I've found that it doesn't. Now, I've read the bib latex manual in order to find the same thing to change the punctuation after the title: same thing, I need rather a "comma" that a "dot". Do you know to do it, please? In your example, it would be a "comma" after Manual Feb 28 '15 at 10:42
• See my updated code. We have to patch the bibliography driver for the ‘book’ entry type. The xpatch package is done for that. Feb 28 '15 at 11:17
