Biblatex Numeric Style – Replace Square with Round Brackets

biblatex

Suppose you have this MWE using numeric style with Biblatex

\documentclass[10pt]{article}
\usepackage[utf8]{inputenc}

\usepackage[italian]{babel}
\usepackage{csquotes} % needed if also biblatex is used

\usepackage[backend=biber,style=numeric]{biblatex}
\addbibresource{references.bib}

\begin{document}

\section{Conclusion}
Adams said ``I always thought something was fundamentally wrong with the universe'' \cite{adams1995hitchhiker}.

\printbibliography

\end{document}

What is the best way to replace square brackets with round brackets in both citations and bibliography?

Best Answer

Update

With biblatex-ext styles, things are a little bit easier since you can use their cite delimiter feature.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=ext-numeric]{biblatex}

\DeclareOuterCiteDelims{parencite}{\bibopenparen}{\bibcloseparen}
\DeclareOuterCiteDelimsAlias{cite}{parencite}
\DeclareInnerCiteDelims{textcite}{\bibopenparen}{\bibcloseparen}

\DeclareFieldFormat{labelnumberwidth}{\mkbibparens{#1}}
\DeclareFieldFormat{shorthandwidth}{\mkbibparens{#1}}

\addbibresource{biblatex-examples.bib}

\begin{document}
Lorem \autocite{sigfridsson}
Lorem \autocites{sigfridsson}{worman}
Lorem \cite{sigfridsson}

\printbibliography
\end{document}

Without `biblate-ext`

With

\DeclareFieldFormat{labelnumberwidth}{\mkbibparens{#1}}
\DeclareFieldFormat{shorthandwidth}{\mkbibparens{#1}}

you get round brackets in the bibliography, for citations you need to copy the definitions from numeric.cbx and change \mkbibbrackets into \mkbibparens

\DeclareCiteCommand{\cite}[\mkbibparens]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}
\DeclareMultiCiteCommand{\cites}[\mkbibparens]{\cite}{\multicitedelim}

\DeclareCiteCommand{\parencite}[\mkbibparens]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}
\DeclareMultiCiteCommand{\parencites}[\mkbibparens]{\parencite}{\multicitedelim}

More radical is

\renewrobustcmd{\mkbibbrackets}{\mkbibparens}

or even

\let\bibopenbracket\bibopenparen
\let\bibclosebracket\bibcloseparen

where all square brackets are replaced by round brackets. This can lead to problems if you do want square brackets in other places in your citations/bibliography.

Note that you will need more intricate tricks for some of the more advanced numeric-derived styles and \textcite.

[Tex/LaTex] biblatex messing up citation entry with lots of authors

This problem is due to biblatex-apa's (apa.bbx's) apaauthor name format; you might want to notify the author of this small bug.

The string and others in the author list sets ifmorenames to true. apaauthor checks for this case whenever a name is printed, not just at the very end of the list; consequently it prints the andothers string ("et al.") after each name.

The fix is to add the following lines to your preamble.

\DeclareNameFormat{apaauthor}{%
  \ifthenelse{\value{listcount}=\maxprtauth\AND\value{listcount}<\value{listtotal}}
    {\addcomma\addspace\ldots\addspace}
    {\ifthenelse{\value{listcount}>\maxprtauth\AND\value{listcount}<\value{listtotal}}
      {}
      {\ifthenelse{\iffieldequalstr{doubtfulauthor}{true}}
        {\mkbibbrackets{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}?}}
        {\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}}}}%
  \ifthenelse{\value{listcount}=\value{listtotal}}% this test is new
    {\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}

Update 2013-10: This has been corrected in biblatex-apa version 6.4 according to a comment below the question from user PLK.

[Tex/LaTex] Citing (author, journalabbr., year) needed

First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.

Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.

Last but not least you have to add the abbreviation fields to the entries.

MWE:

\begin{filecontents}{min.bib}
@article{boisson2003unexpected,
  title={Unexpected protein families including cell defense components feature in the N-myristoylome of a higher eukaryote},
  author={Boisson, B. and Giglione, Carmela and Meinnel, Thierry},
  journal={Journal of Biological Chemistry},
  journalabbr={JBC},
  year={2003},
  publisher={ASBMB}
}
\end{filecontents}
