# How do you hide an article title in BibLaTeX?

I can use

``````\usepackage[bibstyle=numeric,url=false,doi=false]{biblatex}
``````

to hide urls and dois from my bibliography, but

``````\usepackage[bibstyle=numeric,url=false,doi=false,title=false]{biblatex}
``````

will not compile, throwing instead a keyval error.

How can I hide the titles of articles from my bibliography?

Is `\AtEveryBibitem{\clearfield{title}}` what you are after? Or alternatively, `\DeclareFieldFormat[article]{title}{}`. –  Corentin Nov 8 '13 at 5:04
@Corentin, Would I put this somewhere in the header of the LaTeX document source? –  Richard Nov 8 '13 at 5:16
Yes, `\AtEveryBibitem{\clearfield{title}}` is working when placed in the header. –  Richard Nov 8 '13 at 5:17
Yes, in the preamble of your document. –  Corentin Nov 8 '13 at 6:32

1. You can use `\DeclareSourceMap`:

``````\DeclareSourcemap{
\maps[datatype=bibtex]{
\map{
\pertype{article}
\step[fieldset=title, null]
}
}
}
``````
2. You can change the field format of title:

``````\DeclareFieldFormat[article]{title}{}
``````

Both solutions can be done at the preamble.

Please note that `\DeclareFieldFormat[article]{title}{}` can have adverse effects in that it makes `biblatex` think it printed the title when it didn't, potentially messing up the punctuation. The preferred variant is probably `\AtEveryBibitem{\clearfield{title}}`/`\AtEveryCitekey{\clearfield{title}}`. –  moewe Mar 17 at 11:54
