Suppress field "pages" when page is specified in postnote with verbose citations

Question

I'm using the ext-verbose-trad2 biblatex style. When I specify the page of the citation using the command \cite the output prints the pages field of the entry, resulting in a redundant page reference.

Here a brief code as an exemplification

\documentclass[12pt, a4paper, openright, twoside]{memoir}
\usepackage[italian]{babel}
\usepackage[style = ext-verbose-trad2, articlein=false, firstinits=true, ibidpage=true]{biblatex}
\begin{filecontents*}{\jobname.bib}
@inbook{InbookCecchi, 
  author   = {Cecchi, C.},
  title= {Perseverare},
  bookauthor = {Cecchi, C.},
  booktitle = {Diabolic issues},
  editor = {Faffi, F. and Jollie, J. K.},
  date = {1980},
  pages = {15-18},
}
@article{ArticleTotti, 
  author   = {Totti, Q.},
  title= {Grammatica sbagliata},
  journaltitle = {Proceedings in errors},
  number = 12,
  volume = {XV},
  date = {2025},
  pages = {223-567},
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\cite[16]{InbookCecchi}.
\cite[240-251]{ArticleTotti}.
\end{document}

This gives the result:

I want to avoid the underlined pages reference, corresponding to the pages field in the respective entry, since I’m already specifying at which page I’m referring to.

Answer 1

You'll want to use the citepages option.

The option is documented in the biblatex documentation (pp. 62-63) and in the verbose-trad2 style example (pp. 2-3).

You probably want the effect of citepages=omit,, but you may also be interested in citeopages=suppress, or citepages=separate,

\documentclass[12pt, a4paper, openright, twoside]{memoir}
\usepackage[italian]{babel}
\usepackage[
  style=ext-verbose-trad2,
  firstinits=true, 
  articlein=false,
  ibidpage=true,
  citepages=omit,
]{biblatex}
\begin{filecontents}{\jobname.bib}
@inbook{InbookCecchi, 
  author     = {Cecchi, C.},
  title      = {Perseverare},
  bookauthor = {Cecchi, C.},
  booktitle  = {Diabolic issues},
  editor     = {Faffi, F. and Jollie, J. K.},
  date       = {1980},
  pages      = {15-18},
}
@article{ArticleTotti, 
  author       = {Totti, Q.},
  title        = {Grammatica sbagliata},
  journaltitle = {Proceedings in errors},
  number       = 12,
  volume       = {XV},
  date         = {2025},
  pages        = {223-567},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
  \cite[16]{InbookCecchi}
\cite[240-251]{ArticleTotti}
\end{document}
