Citation customisation

Question

Greeting to everyone !

I am helping a friend to write a law-oriented thesis and I am struggling to set in the correct way the citation. In these types of thesis we usually have 2 different types of citations:

• THE FOOT NOTE CITATION: in which we found "Author + title + publisher + year + ... + comment of the writer";
• THE END THESIS BIBLIOGRAPHY: in which we found the standard bibliography WITHOUT the comment of the writer.

The problem is the following:

THIS IS MY MAIN:

\documentclass{article}
% Dimensione dell'area di scrittura -> tra parentesi
% (larghezza, altezza)
\usepackage[a4paper, total={15cm, 20.8cm}]{geometry}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage{xcolor}
\usepackage{graphicx}
\usepackage[citestyle=verbose-ibid, labeldateparts]{biblatex}
\addbibresource{biblio.bib}
\title{FORMALISING ALGORITHMIC FAIRNESS AND UNFAIRNESS IN LEGAL EXPERIENCE}
\author{Veronica Paternolli}
\date{\today}
\begin{document}
\maketitle
[...]
\clearpage
\tableofcontents
\clearpage
\input{sections/introduction}
[...]
\printbibliography
\end{document}

And this is how it look like now:

The question is the following:

We would like to have while using \footcite{ }:

• In the footer [in this order] just "author", "title", "publisher, "date", and, if present, "note".
• In the end bibliography everything else.

Answer 1

To put the note at the end, use addendum instead of note in the bibitems, see this answer by moewe.

To remove it from the Bibliography, use:

\AtEveryBibitem{%
  \clearfield{addendum}%
}

Here is a complete MWE:

\begin{filecontents}[overwrite]{biblio.bib}
@book{wolfgang2017introduction,
  title={Introduction to artificial intelligence},
  author={Wolfgang, Ertel},
  year={2017},
  publisher={Springer},
  addendum = {{This} is a note about this book.}
}
@inproceedings{dymitruk2021borderlands,
  title={Borderlands of the Law and Technology: from Digital Machines to LegalTech},
  author={Dymitruk, Maria},
  booktitle={Legal Tech},
  pages={67--80},
  year={2021},
  organization={Nomos Verlagsgesellschaft mbH \& Co. KG},
  addendum = {{This} is a note about this conference proceedings.}
}
\end{filecontents}
