In my thesis, I have to print the list of publications along with the corresponding impact factor of the journal. While using authoryear style of biblatex package, how can we customize it to print the impact factor as well?

Should we define a new field, or are there any feasible solutions for achieving it? I am sharing what I already have modified in the preamble of my file -

\usepackage[bibstyle=authoryear,
citestyle=phys,
backend=biber,
defernumbers=true,
natbib=true,
%biblabel=brackets,
isbn=false,
maxbibnames=10,
minbibnames=5,
giveninits=true,
hyperref=true,
%urldate=false,
sorting=none
]{biblatex}

\DeclareFieldFormat[article]{volume}{\textbf{#1}\addcomma\space} % Bolds volume of citation and adds comma after volume
\DeclareFieldFormat{pages}{#1} % No prefix for the "pages" field in the bibliography
\DeclareFieldFormat[article]{title}{#1}  % Remove quotes from journal title


%Suppress 'number' preceeding the vol. in bibliography;
\AtEveryBibitem{%
    \clearfield{number}}
%
%Suppress 'month' followed by year in bibliography;
\AtEveryBibitem{%
    \clearfield{month}}


\DeclareNameAlias{sortname}{last-first} % Lists all authors with last name first
\renewcommand{\labelnamepunct}{\addcomma\addspace} % Removes period after year in bibliography
\renewcommand{\revsdnamepunct}{\addspace}% want a comma between last name and initials
\renewcommand{\multinamedelim}{\addcomma\addspace}% want a space but no comma between names
\renewcommand*{\finalnamedelim}{\addcomma\addspace\bibstring{and}\space}% want a space but no comma between penultimate name and 'and' followed by final name
\DeclareSourcemap{% Ignores urldates
  \maps[datatype=bibtex]{
    \map{
      \step[fieldset=urldate, null]
    }
  }
}


\usepackage{xpatch}


\xpatchbibmacro{name:andothers}{% maked the ``et al'' italicized in the bibliography
\bibstring{andothers}%
}{%
\bibstring[\emph]{andothers}%
}{}{}


\renewbibmacro{in:}{% Removes "In" from bibliography entries
\ifentrytype{article}{}{%
\printtext{\bibstring{in}\intitlepunct}}}


\DeclareFieldFormat{labelnumberwidth}{#1.}% from karlkoeller's answer


\defbibenvironment{bibliography}
  {\list
    {\printfield[labelnumberwidth]{labelnumber}}
    {\setlength{\labelwidth}{\labelnumberwidth}%
      \setlength{\leftmargin}{0pt}%
      \setlength{\labelsep}{\biblabelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\itemindent}{\labelwidth}%
      \addtolength{\itemindent}{\labelsep}%
      \setlength{\parsep}{\bibparsep}}%
    \renewcommand*{\makelabel}[1]{\hss##1}}
  {\endlist}
  {\item}

A possible solution was to write manually the impact factor of each journal in the my-ref.bib file and letting it to print at the end. But it interrupts the hyperref which is required in the bibliography, and the link is corrupted.

I tried to definine a new field in biblatex as follows -

\DeclareFieldFormat{impactfactor}{\mkbibparens{IF: #1}} % New format for impact factor
% Define a new bibmacro to print impact factor
\newbibmacro*{impactfactor}{%
  \printfield{impactfactor}%
}

But that also didn't work.

  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Aug 17 '23 at 13:47
  • Thanks for your response. I want to add 'impact factor' in my bibliography list. How to do that using authoryear style in biblatex. – Omkar Rambadey Aug 17 '23 at 14:08
  • Welcome. // Almost always we need to try posted code, i.e. copy and compile it. Your code at the moment can't compile unfortunately. // Please add the missing parts, starting with \documentclass, ending with end{document}, discarding all lines not needed, AND still showing your problem. Including a screenshot of the result may also help. Perhaps you need to include commandline actions as well. // Is impact factor an established term or is it an idea? – MS-SPO Aug 17 '23 at 16:42
  • New fields need to be declared to biblatex first. They cannot be used just like that. You also need to make sure the field is actually printed by adding code to a used bibmacro or driver. It is not enough to define an eponymous bibmacro. See https://tex.stackexchange.com/q/163303/35864 for the several ways you can get hold of a new field. – moewe Aug 17 '23 at 18:32
  • Any news here? I feel that this is basically a duplicate of https://tex.stackexchange.com/q/163303/35864, which shows how to add a new field to the output. – moewe Sep 10 '23 at 07:19
