adding doi-hyperlink on publisher+year on @book entry

Question

I would like to activate the doi-hyperlink over some fields of the bibliography. For @article, these are journal+volume+year+pages. For @book, on publisher+year.

The first goal is fully achieved by the following very useful code written by Marco Daniel in the answer to this thread . I copy&paste it below for convenience. Unfortunately, it does not handle @book bibliography entries. My question is whether someone can edit this code to implement the additional feature of doi-hyperlinks on fields publisher+year for @book entries.

\documentclass{article}
\usepackage[backend=biber,backref=true]{biblatex}
\addbibresource{biblatex-examples.bib}

\usepackage[colorlinks]{hyperref}

\ExecuteBibliographyOptions{doi=false}
\ExecuteBibliographyOptions{doi=false}
\DeclareFieldFormat{doilink}{%
\iffieldundef{doi}{#1}%
{\href{http://dx.doi.org/\thefield{doi}}{#1}}}

\DeclareBibliographyDriver{article}{%
  \usebibmacro{bibindex}%
  \usebibmacro{begentry}%
  \usebibmacro{author/translator+others}%
  \setunit{\labelnamepunct}\newblock
  \usebibmacro{title}%
  \newunit
  \printlist{language}%
  \newunit\newblock
  \usebibmacro{byauthor}%
  \newunit\newblock
  \usebibmacro{bytranslator+others}%
  \newunit\newblock
  \printfield{version}%
  \newunit\newblock
  \usebibmacro{in:}%
  \printtext[doilink]{%
  \usebibmacro{journal+issuetitle}%
  \newunit
  \usebibmacro{byeditor+others}%
  \newunit
  \usebibmacro{note+pages}%
  }%
  \newunit\newblock
  \iftoggle{bbx:isbn}
    {\printfield{issn}}
    {}%
  \newunit\newblock
  \usebibmacro{doi+eprint+url}%
  \newunit\newblock
  \usebibmacro{addendum+pubstate}%
  \setunit{\bibpagerefpunct}\newblock
  \usebibmacro{pageref}%
  \usebibmacro{finentry}}

Answer 1

You can use the same strategy for all entry types: Copy the relevant driver from standard.bbx and add \printtext[doilink]{...} around the stuff you want to link.

The following code shows the approach for the current version of @article and @book.

\documentclass{article}
\usepackage[backend=biber,backref=true]{biblatex}


\usepackage[colorlinks]{hyperref}

\ExecuteBibliographyOptions{doi=false}

\DeclareFieldFormat{doilink}{%
  \iffieldundef{doi}{#1}%
    {\href{https://doi.org/\thefield{doi}}
    {#1}}}


\DeclareBibliographyDriver{article}{%
  \usebibmacro{bibindex}%
  \usebibmacro{begentry}%
  \usebibmacro{author/translator+others}%
  \setunit{\printdelim{nametitledelim}}\newblock
  \usebibmacro{title}%
  \newunit
  \printlist{language}%
  \newunit\newblock
  \usebibmacro{byauthor}%
  \newunit\newblock
  \usebibmacro{bytranslator+others}%
  \newunit\newblock
  \printfield{version}%
  \newunit\newblock
  \usebibmacro{in:}%
  \printtext[doilink]{%
    \usebibmacro{journal+issuetitle}%
    \newunit
    \usebibmacro{byeditor+others}%
    \newunit
    \usebibmacro{note+pages}}%
  \newunit\newblock
  \iftoggle{bbx:isbn}
    {\printfield{issn}}
    {}%
  \newunit\newblock
  \usebibmacro{doi+eprint+url}%
  \newunit\newblock
