Remove the title in a second verbose citation

Question

I need a very specific layout for my university.

My current MWE looks like this:

\documentclass[paper=a4,]{scrreprt} 
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[style=verbose,backend=biber]{biblatex}

\begin{filecontents*}{document.bib}

@book{Belyi.2015,
    year    = {2015},
    title   = {{S}tates and markets in hydrocarbon sectors},
    author  = {Belyi/Andrei/Talus},
}

\end{filecontents*}
\addbibresource{document.bib}

\renewcommand{\mkbibnamelast}[1]{\mkbibemph{#1}\addcomma} 
\DeclareFieldFormat*{title}{#1\addcomma}

\DeclareFieldFormat{parens}{\mkbibparens{#1}}
\renewbibmacro*{date}{\printtext[parens]{\printdate}}

\begin{document}
First Note\footnote{\cite{Belyi.2015}}.

Second note\footnote{\cite{Belyi.2015}}.

\printbibliography
\end{document}

The current output looks like this:

Belyi/Andrei/Talus, States and markets in hydrocarbon sectors, (2015)

Belyi/Andrei/Talus, States and markets in hydrocarbon sectors

Now I want to get rid of the title in the second citation. My guess is it works somehow with ifciteseen but I can't seem to get it right.

• Bonus: Is there a possibility to end all citations with a dot? My current solution to this is to end the footnote but it would be nice if latex could do it for me.

Answer 1

The macro cite:short is used for short (subsequent) citations in the verbose styles. There is no need for an additional \ifciteseen test. That test is already executed to decide whether to call cite:full or cite:short.

You can use the test \ifsingletitle (activated with the option singletitle) to test if the author list is unique, in that case the title will be dropped. If the author list is not unique, i.e. there are several works with the same list of authors, the title is displayed to allow for a disambiguation of the references.

Please note how I modernised and modified some of your code and filled the .bib entry in the appropriate format (authors should always be separated with and and not with /).

The bonus question can be solved by using \autocite (or \footcite).

\documentclass[paper=a4,]{scrreprt} 
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[style=verbose,backend=biber,singletitle]{biblatex}

\renewcommand*{\newunitpunct}{\addcomma\space}

\renewcommand{\mkbibnamefamily}[1]{\mkbibemph{#1}} 
\DeclareDelimFormat*{multinamedelim}{\addslash}
\DeclareDelimAlias{finalnamedelim}{multinamedelim}

\DeclareDelimFormat{nametitledelim}{\addcomma\space}

\DeclareFieldFormat*{title}{#1}
\DeclareFieldFormat*{citetitle}{#1}

\renewbibmacro*{cite:short}{%
  \printnames{labelname}%
  \ifsingletitle
    {}
    {\setunit*{\printdelim{nametitledelim}}%
     \printtext[bibhyperlink]{%
       \printfield[citetitle]{labeltitle}}}}

\DeclareFieldFormat{parens}{\mkbibparens{#1}}
\renewbibmacro*{date}{\printtext[parens]{\printdate}}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@collection{Belyi.2015,
  year      = {2015},
  title     = {States and Markets in Hydrocarbon Sectors},
  editor    = {Belyi, Andrei V. and Talus, Kim},
  publisher = {Palgrave},
}
\end{filecontents*}
\addbibresource{\jobname.bib}

\begin{document}
First Note\autocite{Belyi.2015}.

Second note\autocite{Belyi.2015}.

\printbibliography
\end{document}

Modification for family names in first/full citations

\renewbibmacro*{cite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \usedriver
      {\DeclareNameAlias{sortname}{labelname}}
      {\thefield{entrytype}}}%
  \usebibmacro{shorthandintro}}
