# Format an @article's title

TL;DR: How do I DeclareFieldFormat on an @article's title?

Having a .bib entry like this

@article{x,
title={Article Title},
author={Author},
journal={Journal Name},
year={2019}
}


And using [style=alphabetic,sorting=nyt,backend=biber,maxbibnames=999,useprefix=true]{biblatex}, the bibliography entry gets

[Aut19] Author. “Article Title”. In: Journal Name (2019).

However, I would like to make the Article Title italics instead of in quotes:

[Aut19] Author. Article Title. In: Journal Name (2019).

I tried \DeclareFieldFormat{title}{\emph{#1}}, which works fine with (for example) @misc, but not with an @article. How do I do that?

• \DeclareFieldFormat[article]{title}{\emph{#1}}. See also tex.stackexchange.com/q/462133/35864. biblatex allows you to specify type-specific field formats. \DeclareFieldFormat{title} redefines the generic format that is used if there are no type-specific definitions. @articles have a type-specific default and that has to be overwritten with a type-specific declaration: \DeclareFieldFormat[article]{title}. If you want to overwrite all declarations at once, use the starred form \DeclareFieldFormat*{title} – moewe Mar 1 at 16:40
• I knew it must be easy ;) Thanks. Would you post this as a reply so I can accept it? – Marian Mar 1 at 17:01

As explained in Remove Quotation Marks from Style biblatex's field formats allow for generic and type-specific formatting. @articles have a type-specific field format and so the definition has to happen with the type argument.

Use

\DeclareFieldFormat[article]{title}{\mkbibemph{#1}}


to turn only titles of @article entries into italics and leave everything else as is.

Use

\DeclareFieldFormat*{title}{\mkbibemph{#1}}


to remove all type-specific formatting and make all titles into italics.

See the already linked Remove Quotation Marks from Style for more extensive examples and explanations.
