\section{Aim of the package}

The default citation styles \verb+verbose-trad1+;\verb+verbose-trad2+;\verb+verbose-trad3+ use the \emph{op. cit.} form in order to have shorter reference when a title have been already cited.

However, when you cite two  entries which share the same \bibfield{booktitle} but not the same \bibfield{title}, the \emph{op. cit.} mechanism does not work.

For example we obtain the following example:

\begin{quotation}
\makeatletter
\cite{Pleiade_Barnabe}

\csundef{blx@bsee@\the\c@refsection}

\cite{Pseudo-Hippolyte}

\csundef{blx@bsee@\the\c@refsection}

\cite{Pleiade_Tite}

\csundef{blx@bsee@\the\c@refsection}

\cite{Pseudo-Epiphane}
\makeatother
\end{quotation}

While we would like to obtain:

\citereset


\begin{quotation}

\cite{Pleiade_Barnabe}

\cite{Pseudo-Hippolyte}

\cite{Pleiade_Tite}

\cite{Pseudo-Epiphane}
\end{quotation}

The aim of this package is to enable such abbreviation.

\section{Use}

The \verb+biblatex-opcit-booktitle+ package must be loaded after the \verb+biblatex+ package, which must be at version 3.4 or greater. You must use a \verb+verbose-trad+ citation style. For example:

\begin{minted}{latex}
\usepackage[bibstyle=verbose,citestyle=verbose-trad1,citepages=omit]{biblatex}
\usepackage{biblatex-opcit-booktitle}
\end{minted}

In order to know when two entry share the same \bibfield{booktitle}, you must use the crossref mechanism of \biblatex. In the case of the previous example, we used:
\begin{minted}{latex}
@book{Pleiade2,
  Address = {Paris},
  Number = {516},
  Publisher = {Gallimard},
  Series = {Bibliothèque de la Pléiade},
  Title = {Écrits apocryphes chrétiens},
  Volume = {2},
  Year = {2005}}

@bookinbook{Pleiade_Barnabe,
  Annotator = {Enrico Norelli},
  Crossref = {Pleiade2},
  Pages = {627-642},
  Title = {Actes de Barnabé},
  Translator = {Enrico Norelli}}

@bookinbook{Pleiade_Tite,
  Annotator = {Willy Rordorf},
  Bhg = {1850z},
  Crossref = {Pleiade2},
  Pages = {609-615},
  Title = {Actes de Tite},
  Translator = {Willy Rordorf}}

@book{Schermann1907,
  Address = {Leipzig},
  Editor = {Theodor Schermann},
  Publisher = {Teubner},
  Title = {Prophetarum vitae fabulosae indices apostolorum discipulorumque Domini Dorotheo · Epiphanio · Hippolyto aliisque vindicata},
  Year = {1907}
}

@bookinbook{Pseudo-Hippolyte,
  Author = {{Pseudo-Hippolyte}},
  Crossref = {Schermann1907},
  Pages = {163-170},
  Title = {Index apostolorum discipulorumque Domini}}

@bookinbook{Pseudo-Epiphane,
  Author = {{Pseudo-Épiphane}},
  Crossref = {Schermann1907},
  Pages = {107-126},
  Title = {Index apostolorum discipulorumque Domini}}
\end{minted}

There is not other thing to do!

The feature works with these entrytypes:  \bibtype{inbook}, \bibtype{incollection}, \bibtype{inproceedings}, \bibtype{bookinbook}. 

If you define a \bibfield{shorttitle} in the main entry, it will be used instead of the full title when we need an abbreviated form.
\subsection{Limits}

We have not implemented options to use abbreviation like \verb+ibid+, because we want to have not ambiguous abbreviated forms. 

If you have redefined the \verb+cite+ bibliographic macro, you must changes:
\begin{minted}{latex}
\usebibmacro{cite:full}%
       \usebibmacro{cite:save}
\end{minted}

by:

\begin{minted}{latex}
\usebibmacro{cite:test:ifrelated}
\end{minted}

\subsection{Use with own citation style}

If you have created your own citation style file (\verb.+cbx.), you must create a bibliographic driver called \verb+inbook:rel:<yourcitationstyle>+. You can look at the model \verb+inbook:rel:verbose-trad-xxx+  in the .sty file, or just use \cs{DeclareBibliographyAlias} to use an already existing model.

If your citation style is public (i. e. published on CTAN), please contact us: we could provide the bibliographic driver directly in this package.

If you have created your own \verb+cite+ bibmacro, this bibmacro must call, directly or indirectly the `cite:test:ifrelated` bibmacro (or your adaptation of this bibmacro).

\subsection{Customization}

You can change the \verb+inbook:rel:verbose-trad-xxx+ bibliographic driver to customize the way the main title is printed, \verb+xxx+ meaning 1, 2, or 3, depending of you specific citation style.
