# Changing citation style using biber

I have two problems regarding the citation style, see example.

1. At first, the citation should be without the title of the work for space sparing reasons.

2. Second, the volume.number (Month Year) notation should be replaced by a \bf{volume}, number (year) notation.

Here is the LaTeX code:

\documentclass[open=right,titlepage=on,headsepline=on,numbers=enddot,ngerman,12pt,draft]{scrbook}
\usepackage[ngerman]{babel}
\usepackage[citestyle=verbose-ibid,bibstyle=authortitle,labelyear=true,backend=biber,isbn=false,url=false,doi=false,eprint=false]{biblatex}
\bibliography{mini}
\begin{document}
\footcite{sigmund_mechanism_1973}
\printbibliography
\end{document}


and this is the mini.bib file:

@article{sigmund_mechanism_1973,
title = {A mechanism of surface micro-roughening by ion bombardment},
volume = {8},
issn = {0022-2461, 1573-4803},
doi = {10.1007/BF00754888},
abstract = {},
language = {en},
number = {11},
urldate = {2014-02-24},
journal = {J Mater Sci},
author = {Sigmund, Peter},
month = nov,
year = {1973},
keywords = {Characterization and Evaluation Materials, Industrial {Chemistry/Chemical} Engineering, Mechanics, Polymer Sciences},
pages = {1545--1553},
file = {}
},

• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – karlkoeller Apr 1 '14 at 8:08
• @user49013: Please reduce your latex code to a MWE – strpeter Apr 1 '14 at 8:41
• Are you sure it is the verbose-ibid citation style you want? One point of the "verbose" styles is that they can be used without a list of references, since everything is there (in the first citation, at least), which is a reason why they won't omit the title. With style=authortitle-terse you have a predefined style that only prints the author name (providing there is just one title by that author, of course). – pst Apr 1 '14 at 8:44
• style=authortitle-terse gives in my case only the name. What want is in the footnote autor, journal, \bf{vol}, number (year) and in the bibligrapy autor, title, journal, \bf{vol}, number (year). – user49013 Apr 1 '14 at 8:56
• @strpeter: Done. Hopefully this helps for answering the question. – user49013 Apr 1 '14 at 15:39

You could try these modifications to verbose-ibid

We use a comma for punctuation

\renewcommand*{\newunitpunct}{\addcomma\space}


The language list will not be displayed, we also drop the title in citations.

\AtEveryBibitem{\clearlist{language}}
\AtEveryCitekey{\clearlist{language}\clearfield{title}}


The volume is printed in bold

\DeclareFieldFormat[article]{volume}{\mkbibbold{#1}}


No "In:" ...

\renewbibmacro{in:}{}


There is a comma between volume and number in @articles

\renewbibmacro*{volume+number+eid}{%
\printfield{volume}%
\printfield{number}%
\printfield{eid}}


There is no such thing as a short citation here, so we always either print the full thing or just ibid.

\renewbibmacro*{cite}{%
\usebibmacro{cite:citepages}%
\global\togglefalse{cbx:loccit}%
\ifciteseen
{\iffieldundef{shorthand}
{\ifboolexpr{
test {\ifciteibid}
and
not test {\iffirstonpage}
}
{\usebibmacro{cite:ibid}}
{\usebibmacro{cite:full}}}
{\usebibmacro{cite:shorthand}}}
{\usebibmacro{cite:full}}}
