[Tex/LaTex] Remove quotes from inbook reference title with biblatex

biblatexbibtex

I use BibTeX and biblatex to create a bibliography. In my BibTeX database I define a @inbook reference with author, title, year and booktitle. Now the problem is that the reference is rendered as:

Author (year): “Title”. In: BookTitle.

I need to remove the quotes around the title.

I already have a custom cite style file with some other definitions, but I did not find where to remove these quotes.

Best Answer

The default definitions for this are in biblatex.def. In your case, they are:

\DeclareFieldFormat[article,inbook,incollection,inproceedings,patent,thesis,unpublished]{citetitle}{\mkbibquote{#1\isdot}}
\DeclareFieldFormat[article,inbook,incollection,inproceedings,patent,thesis,unpublished]{title}{\mkbibquote{#1\isdot}}

So you can add the following to your own .tex file (or to a biblatex.cfg):

\DeclareFieldFormat[inbook]{citetitle}{#1}
\DeclareFieldFormat[inbook]{title}{#1}

The first removes the quotation marks from your citations; the second from the bibliography.

\documentclass{article}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@InBook{entry1,
  author =   {Author, A.},
  booktitle =    {Main Title of Book},
  title =    {InBook Title without Quotation Marks},   
  publisher =    {The Publisher},
  date =     3000,
  location =     {CityPlace},
  pages =    {63--90},
}
@article{entry2,
  author =   {Author, A.},
  title =    {Title of Article},
  journal =      {Journal Title},   
  volume =       {50},
  number =       {3},
  date =     3000,
  pages =    {63--90},
}
\end{filecontents}

\usepackage[style=authortitle,backend=bibtex]{biblatex}
\addbibresource{\jobname.bib}

\DeclareFieldFormat[inbook]{citetitle}{#1}
\DeclareFieldFormat[inbook]{title}{#1}

\begin{document}

\cite{entry1,entry2}

\printbibliography

\end{document}
