Hyperlink each bib entry to its DOI page

Question

Can I have each bib entry hyper-linked to its DOI page? i.e. clicking anywhere on the bib entry (preferably anywhere, but if not possible, at least on the title of the paper) in the PDF should open the link to its DOI page. I am willing to ensure that each entry in the bib file has a DOI/URL.

I'm using TexShop on Mac OS X Snow Leopard, and use pdflatex/bibtex to compile my dissertation.

Answer 1

With respect, it doesn't make much sense to have the ENTIRE bib entry link to the DOI page, since, an individual bibliography record may have BOTH URL and DOI's, either, or neither.

I use the following command, along with the hyperref package, which gives a blue colored hyperlink to the DOI webpage for the bibliography entries that have DOI records.

In the preamble, put the following:

\usepackage[hidelinks]{hyperref} %boxes hidden, remove hidelinks if boxes are desired.

Then before the bibliography is called:

\def\mybibdoicolor{\color{blue!75!black}} %change color to suit.
\newcommand*{\doi}[1]{\href{http://dx.doi.org/\detokenize{#1} {\raggedright\mybibdoicolor{DOI: \detokenize{#1}}}}

Finally, the bibliography can be called:

\bibliography{BIBDATAFILE}

An exerpt from my output is displayed below, noting the blue DOI record/s held in references [41-43], each can be clicked from inside PDF, in such event, the user would be redirected to the relevant site. In this case, as an example, should the user click on the DOI record inside [41], he/she would be redirected to http://dx.doi.org/10.1098/rspa.1925.0147, which in turn redirects the user to the publication.

Answer 2

Since I could not get the solutions here working with the latest biblatex, I am posting here two alternate approaches that worked for me. Both were posted by others for other questions. I just reproduce and link them here for reference since they are quite hard to find (at least it took me half a day finding them).

A lot of other solutions to make individual parts of the citation clickable exist, but actually making the whole thing into a link is tricky. Most solutions I found make it necessary to rebuild the citation style manually and are therefore not portable from one document to the next. These two seem to not touch the appearance but just wrap the item into a hyperlink.

1 In Document Solution

Moewe posted the following solution:

\newbibmacro{string+doiurl}[1]{%
  \iffieldundef{doi}
    {\iffieldundef{url}
       {#1}
       {\href{\thefield{url}}{#1}}}
    {\href{https://doi.org/\thefield{doi}}{#1}}}

\makeatletter
\def\blx@driver#1{%
  \ifcsdef{blx@bbx@#1}
    {\usebibmacro{string+doiurl}{\csuse{blx@bbx@#1}}}
    {\ifcsdef{blx@bbx@*}
       {\blx@warning{%
          No driver for entry type '#1'.\MessageBreak
          Using fallback driver}%
        \usebibmacro{string+doiurl}{\csuse{blx@bbx@*}}}
       {\blx@error
          {No driver found}
          {I can't find a driver for the entry type
           '\abx@field@entrytype'\MessageBreak
           and there is no fallback driver either}}}}
\makeatother

2 Biblatex Config File

Carlos Lanziano's answer number two contains a config file, that makes the entire entry into a hyperlink.

Save the following as biblatex-dm.cfg next to your document:

\newcommand{\doiorurl}{%
  \iffieldundef{doi}
    {\iffieldundef{url}
       {}
       {\strfield{url}}}
    {http://dx.doi.org/\strfield{doi}}%
}

\newcommand{\bibdrivercontent}[1]{%
 \ifboolexpr{%
   test {\ifhyperref}
   and
   not test {\iftoggle{bbx:url}}
   and
   not test {\iftoggle{bbx:doi}}
  }
  {\href{\doiorurl}{#1}}
  {#1}%
}

\let\OldDeclareBibliographyDriver\DeclareBibliographyDriver
\renewcommand{\DeclareBibliographyDriver}[2]{\OldDeclareBibliographyDriver{#1}{\bibdrivercontent{#2}}}

Answer 3

There is the urlbst package. It provides a perl script to modify existing .bst files with url and enclose the whole citation in an hyperlink.

Answer 4

To make a whole reference an hyperlink (with biblatex) using url (it is to do the same using doi)

\AtEveryBibitem{%
  \iffieldundef{url}
    {}
    {\href{\thefield{url}}{\usedriver{\thefield{article}}}
    \csdef{blx@bbx@\thefield{entrytype}}{}}%
}

Answer 5

Small correction to the solution by Guido:

\AtEveryBibitem{%
  \iffieldundef{url}
    {}
    {\href{\thefield{url}}{\usedriver{\thefield{article}}\thefield{entrytype}}}
    \csdef{blx@bbx@\thefield{entrytype}}{}}%
}

That yields the expected result for me.
