\section{Introduction}

The standard biblatex fields allow to describe the author of a work, with the so called \bibfield{authors} field. However, some works are published without name, or with pseudonyme, but the scholars know the real author. This package adds a new field \bibfield{realauthor}, to specify the knew real author.

It also add a new field \bibfield{realeditor}, to specify the knew real editor.

\section{Basic use}

\subsection{Requirement}

The packages require \biblatex~3.5 or later.

\subsection{The .bib file}
Basically, you just have to add the real author / editor name in the field \bibfield{realauthor} / \bibfield{realdeditor}, like in the following examples: 

\inputminted{tex}{example-realauthor.bib}

\subsection{Loading of the \biblatex package}

When loading the \biblatex package, use the \namebibstyle{realauthor}  bibstyle, which is based on the \namebibstyle{verbose} bibstyle:

\begin{minted}{latex}
\usepackage[citestyle=verbose,bibstyle=realauthor]{biblatex}
\end{minted}

Not that the package patches some bibmacro.
If you redefine them, don't forget the patches\footnote{We suppose that, if you redefine them, you could understand the packages.}.
Here the list of macro patched:
\begin{itemize}
  \item author;
  \item author/editor+others;
  \item author/translator+others;
  \item author/editor+others/translator+others;
  \item bbx:editor;
  \item byeditor;
  \item byeditor+others;
  \item cite:name (patched at the beginning of the document);
\end{itemize}

\subsection{Example of result}

By default, the real author name is printed in brackets, with an equal, between fine nonbreak spaces,  when a pseudonym is also use:
\begin{quotation}
\cite{LeClerc1686}

\cite{Simon1686}
\end{quotation}

\subsection{\bibfield{Labelname} field}\label{field:label} 

This package, since version 2.0.0, declares  the \bibfield{realauthor} name as the \bibfield{labelname}, if a \bibfield{author} name is not defined.

That implies this field is use for:
\begin{itemize}
  \item Sorting.
  \item \emph{ibid} / \emph{op. cit} abreviation.
\end{itemize}

Note that this field is not affected by \verb+useauthor+ option, but it is by \verb+userealauthor+ option \secref{userealauthor}.

Used in a bibliography macro or driver, \cmd{ifuserealauthor}\mprm{true}\mprm{false} expands to \prm{true} if the \opt{userealauthor} option is enabled (either globally or for the current entry), and \prm{false} otherwise.

There is also a \verb+userealeditor+ option and a \cmd{ifuserealeditor} field, similar, but for \bibfield{realeditor} field.

\subsection{Sorting}\label{sorting}

The default sorting schemes \verb+nty+ is problematic, because it doesn't consider the \bibfield{realauthor} field  as a name. That is why the package provides two sorting scheme:

\begin{itemize}
   \item  \verb|realauthor|, which  but considers the \bibfield{realauthor} and \bibfield{realeditor} fields to sort list by authors' name. If an entry has both \bibfield{realauthor} and \bibfield{author}, only the \bibfield{author} field will be used.
  \item  \verb|anonymous+realauthor|, which push the anonymous texts at the beginning of the list (as the \verb+anonymous+ sorting of the \emph{biblatex-anonymous+} package), but considers the \bibfield{realauthor} and \bibfield{realeditor} fields to sort list by authors' name (as the \verb+realauthor+ sorting).
\end{itemize} 
  See the example file to have an illustration.
  
 
 +The package also provides \verb-realauthor+manuscripts- and  \verb-realauthor+anonymous+manuscripts- sorting schemes to use in combination with the \emph{biblatex-manuscripts-philology} package (please read handbook of this package for more details about it).
 
\section{Disable realauthor use}\label{userealauthor}

The package, or rather \biblatex, defines an \verb+userealauthor+ option, which can be settable on a per-entry basis in the \bibfield{options} field, or by entrytype, using \cmd{ExecuteBibliographyOptions}, or globally, when loading \biblatex. 

This option, when set to false:
\begin{itemize}
	\item Disable use of \bibfield{realauthor} as label name.
	\item Disable use of \bibfield{realauthor} for sorting.
	\item Before the version 2.4.0. with the default style, and contrary to the \verb+useauthor+ option, also disabled printing of \bibfield{realauthor}. From version 2.4.0, if you don't want to print the field, don't use the package\ldots.
\end{itemize}

The same is true for \opt{realeditor} option for the \bibfield{realeditor}. 

\section{Customization}

You can redefine the \cmd{mkrealauthor} command to change the way the real author name is printed. Default value is:

\begin{minted}{tex}
\newcommand{\mkrealauthor}[1]{\mkbibbrackets{#1}}
\end{minted}

You can also redefine the \cmd{realauthorequalsign} command to change the sign before the real author name when a pseudonym is also used. Default value is:

\begin{minted}{tex}
\newcommand{\realauthorequalsign}{\addnbthinspace=\addnbthinspace}
\end{minted}

There are also \cmd{mkrealeditor}, which by default calls \cmd{mkrealauthor}, and \cmd{realeditorequalsign}, which by default calls \cmd{realauthorequalsign}.

For more customization, you have to redefine the macros defined in \file{realauthor.bbx}.




\section{Use with biblatex-manuscripts-philology}

To use this package with the features of \verb+biblatex-manuscripts-philology+, you must use the package \verb+biblatex-multiple-dm+.
