# biblatex: Make title hyperlink to doi url (if available)

I'm using biblatex with the standard bibliography style. How or what should I modify so that the title is turned into a link pointing to a suitable doi url? (of course only if the doi is available)

I used the default example bib from the current biblatex documentation which is available on every TeX distribution. The two entries have both a doi entry in the bib file:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber]{biblatex}
\bibliography{biblatex-examples}
\ExecuteBibliographyOptions{doi=false}
\newbibmacro{string+doi}[1]{%
\iffieldundef{doi}{#1}{\href{http://dx.doi.org/\thefield{doi}}{#1}}}
\DeclareFieldFormat{title}{\usebibmacro{string+doi}{\mkbibemph{#1}}}
\DeclareFieldFormat[article]{title}{\usebibmacro{string+doi}{\mkbibquote{#1}}}
\begin{document}
A reference to~\cite{kastenholz} and~\cite{sigfridsson}.
\printbibliography
\end{document}


With the latest biblatex update there is also a star version for \DeclareFieldFormat which refers to all entry types.

• @Herbert, would it be possible to make the hyperlinks conditional? What I mean is, if both URL and DOI are available, use DOI, if only URL is available, use URL. Also, you mentioned that there must (should?) be a star version for \DeclareFieldFormat to capture all entry types. Do you know the command for that? – Jörg Mar 16 '12 at 14:28

• Thanks so much! I'm using this: However it appears to not work when the item is a conference paper. Journal papers will have the hyperlinks, but conference papers don't. Is there a way to fix this? – RobertHannah89 Mar 13 '18 at 16:31
• The MWE is working, I then tried to do the same with the filecontents and my own citation entries, however, the link would not show up. I then downloaded the actual biblatex-examples file here and made a same one with filecontents. But the link still did not appear. – zyy Jan 13 at 5:31
