+Overview
+========
+
+`icite` is designed to produce from BibTeX or BibLaTeX bibliographical
+databases the different indices of authors and works cited which are
+called \emph{indices locorum citatorum}. It relies on a specific
+`\icite` command and can operate with either BibTeX or BibLaTeX.

+
+Installation 
+============
+
+1.  Run `'latex icite.ins'` to produce the `icite.sty`
+    file;
+
+2.  To finish the installation you have to move the `icite.sty` file into
+    a directory where LaTeX can find them. See the FAQ on `texfaq.org`
+    at <https://texfaq.org/FAQ-inst-wlcf> for more on this.
+
+
+Development, Git Repository 
+===========================
+
+Browse the code 
+---------------

+% \section{Introduction}
+% \label{sec:introduction}
+% Bib\LaTeX\ features a very powerful internal mechanism which
+% supports indexing of citations and bibliographic entries and can be
+% activated by a simple |indexing| option in the preamble. However, by
+% default, only the authors and the works cited are inserted in the
+% index. Furthermore, authors and works are indexed separately and
+% only inserted in the global index that is generated by
+% \cs{makeindex}. Another limitation is that the references are also
+% excluded from the index.
+%
+% Notwithstanding these limitations, it is quite possible to typeset
+% \emph{indices locorum citatorum} with Bib\LaTeX, but this remains an
+% intricate business and requires knowing how to redefine and/or patch
+% standard and internal Bib\LaTeX\ commands.
+%
+% The \package{icite} package is but a modest piece of software which
+% addresses this situation. It relies on citation commands, but does
+% not require Bib\LaTeX. Instead, \hologo{BibTeX} can be used as
+% \package{icite} uses the \package{usebib}
+% package\footnote{\cite{usebib}} to build the indices by drawing
+% directly from the bibliographic database.
+%
+%
+% \section[The \package{icite} package]{The \textsf{icite} package}
+% The \package{icite} package is loaded as usual like so:---
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \usepackage[<options>]{icite}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+%
+% \package{icite} may be loaded with two optional \enquote*{named
+% arguments} either of which is set using the syntax
+% \meta{key}$=$\meta{value}. The description of the optional arguments
+% follows:---
+%
+% \DescribeOption{citecmd}\label{ref:citecmd}
+% |citecmd|$=$\meta{command}\hfill\tcboxverb{Default: cite}\\
+% \meta{command} may be any citation command accepted by
+% \hologo{BibTeX} or Bib\LaTeX. This option is used by the \cs{icite}
+% command that is described below. By default, \cs{icite} uses the
+% \cs{cite} command to insert citations in the body text.
+%
+% \DescribeOption{defaultindex}
+% |defaultindex|$=$|none|\verb+|+\meta{index\_name}\hfill%
+% \tcboxverb{Default: not set}\\
+% \meta{index\_name} is the name of the index in which all passages
+% cited with the \cs{icite} command are to be found by default. As
+% this option is not initally set, \cs{icite} naturally inserts cited
+% passages in the default general index, unless |defaultindex| is set
+% to the value |none|, in which case indexing is disabled. It must be
+% noted that this named argument does not need a value as it defaults
+% to |loccit| if it is used alone. This is an easy way to have all
+% passages cited indexed in a separate index named |loccit|.
+%
+% \paragraph{Bibliographic database}
+% \DescribeMacro{\bibinput} Once \package{icite} is loaded, it must be
+% connected to at least one bibliographic |.bib| file. To that end,
+% \package{icite} uses the same \cs{bibinput} command as
+% \package{usebib}.\footnote{Please refer to \cite[1]{usebib} for more
+% detailed information on how to use this command.} An example
+% follows:---
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  % load icite, have \icite use \autocite by default, and insert cited
+  % passages in a separate index named 'loccit':
+  \usepackage[citecmd=autocite, defaultindex]{icite}
+  % note that the .bib file must be stripped of its extension:
+  \usebib{bibliography} % that is: load bibliography.bib
+\end{code}
+% \iffalse
+%</example>
+% \fi
+%
+% \paragraph{Styling the titles}
+% \DescribeMacro{\SetTitleStyle} By default, \package{icite} prints
+% the titles of the works cited in italics.\\
+% \cs{SetTitleStyle}\marg{formatting directives} can be used in the
+% preamble only to customize the way titles are displayed in the
+% indices, like so:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \SetTitleStyle{\textbf{#1}}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% As this example shows, |#1| is the token that is replaced with the
+% actual title in the formatting directives of the \cs{SetTitleStyle}
+% command.
+%
+% \subsection{Entry fields}
+% \subsubsection{Author names}
+% To process author names, \package{icite} uses the following entry
+% fields:
+% \begin{description}
+% \item[author] As for example in |author = {Ullmann, Manfred}|, which
+% is satisfactory in most cases.
+% \item[indexauthor] This field is not set by Bib\LaTeX. However, it
+% may be used as a fallback field for multiple or complex names.
+% \item[sortname] This standard Bib\LaTeX\ which is never printed may
+% be used to modify the sorting order of the index entries.
+% \end{description}
+%
+% \paragraph{Example}
+% From a given entry such as: \\[1ex]%
+% |author = {|\prname{.hunayn ibn 'is.hAq al-`ibAdiyy, 'abU
+% zayd}|}|\\[1ex]%
+% it may prove useful to define an additional |indexauthor| field to
+% have printed in the index only the relevant part of the name, like
+% so: \\[1ex]%
+% |indexauthor = {|\prname{.hunayn ibn 'is.hAq}|}| or
+% |indexauthor = {|\prname{.hunayn}|}|\\[1ex]
+% But in the end, the |sortname| field is also needed because the
+% diacritics must be discarded so that the name be sorted
+% properly:\\[1ex]%
+% |sortname = {|Hunayn ibn Ishaq|}|
+%
+% \subsection{Titles}
+% To process titles, \package{icite} uses the following entry fields:
+% \begin{description}
+% \item[title] The full title of the work.
+% \item[shorttitle] The title in an abbriged form. If this entry is
+% set, it takes precedence over the |title| field in the printed index.
+% \item[indextitle] This field may be used to have a title such as
+% \emph{The {\TeX}Book} printed in the index as \emph{{\TeX}Book, The}.
+% \item[indexsorttitle] Like |sortname| for author names, this field is
+% used for sorting only and is never printed. From the previous
+% example, it may be used like so: \\%
+% |indexsorttitle = {TEXBook}|
+% \end{description}
+% 
+% \section{Basic use}
+% \DescribeMacro{\icite} \package{icite} provides the \cs{icite}
+% command which both inserts a formatted citation in the body text and
+% an entry corresponding to the passage cited in the index. This
+% command is to be used in place of any \hologo{BibTeX} or Bib\LaTeX\
+% citation command the syntax of which is
+% \cs{command}\oarg{pre}\oarg{post}\marg{key}. It must be noted that
+% only standard citation commands are supported, with the exception of
+% those mentioned as qualified citation lists or so-called
+% \enquote*{multicite} commands. The full syntax of \cs{icite}
+% follows:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \icite[<pre>][<post>]{<key>}[<command>]
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% Where \oarg{command} can be used as a further optional argument to
+% specify a standard citation command that \cs{icite} should emulate
+% instead of the default \cs{cite} command or any other command set as
+% default in the preamble by means of the |citecmd| global
+% option.\footnote{See above, \vref{ref:citecmd}.}
+%
+% \paragraph{Example} The following example illustrates how
+% \package{icite} can be used in combination with Bib\LaTeX\ and the
+% \package{imakeidx} package to have the passages cited sorted and
+% printed in a separate, specific \enquote*{Index of Passages
+% Cited}:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  % preamble
+  % load icite, have \icite use \autocite by default, and insert cited
+  % passages in a separate index named 'loccit':
+  \usepackage[citecmd=autocite, defaultindex]{icite}
+  % load bibliography.bib
+  \usebib{bibliography}
+
+ % load biblatex (with oxnotes, \autocite acts as \footcite)
+ \usepackage[style=oxnotes]{biblatex}
+ \addbibresource{bibliography.bib} % mind the extension here
+
+ % load imakeidx and use xindy to have the numbers sorted properly
+ \usepackage[xindy]{imakeidx}
+ \makeindex[name=loccit, title=Index of Passages Cited (modern authors)]
+\end{code}
+% \iffalse
+%</example>
+% \fi
+%
+% Then \cs{icite} can be used like so:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \section*{\cs{icite} in action}
+  Let us start with four citations of the same reference, to make sure
+  that they are all indexed and sorted properly:
+  one\icite[123]{Ullmann1970}, two\icite[231]{Ullmann1970},
+  three\icite[81]{Ullmann1970} and four\icite[18]{Ullmann1970}.
+
+  Let us continue with four other citations out of two other
+  references: one\icite[90]{Bürgel2016}, two\icite[370]{Dols1987},
+  three\icite[205]{Bürgel2016} and four\icite[380]{Dols1987}.
+
+  Finally, let us have \cs{icite} use \cs{textcite} to cite
+  \icite[123]{Endress1992}[textcite], and again, this time in a
+  footnote\icite[86]{Endress1992}.
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% 
+% \begin{tcblisting}{text only}
+%   \section*{\cs{icite} in action}
+%   Let us start with four citations of the same reference, to make
+%   sure that they are all indexed and sorted properly:
+%   one\icite[123]{Ullmann1970}, two\icite[231]{Ullmann1970},
+%   three\icite[81]{Ullmann1970} and four\icite[18]{Ullmann1970}.
+%
+%   Let us continue with four other citations out of two other
+%   references: one\icite[90]{Bürgel2016}, two\icite[370]{Dols1987},
+%   three\icite[205]{Bürgel2016} and four\icite[380]{Dols1987}.
+%
+%   Finally, let us have \cs{icite} use \cs{textcite} to cite
+%   \icite[123]{Endress1992}[textcite], and again, this time in a
+%   footnote\icite[86]{Endress1992}.
+% \end{tcblisting}
+% 
+% All indices and the contents of the \hologo{BibTeX} file that has
+% been used can be found below in the appendix
+% (\vrefrange{ref:indices}{ref:icite-bib} respectively). As can be
+% seen by comparing the bibliography generated in the footnotes with
+% the text printed in the index, \package{icite} prints as expected
+% the abbridged forms of the titles when they are
+% available. Furthermore, as a default citation command set in the
+% preamble, the \enquote*{oxnotes} Bib\LaTeX\ option of
+% \package{biblatex-oxref} style package makes \cs{autocite} behave
+% like \cs{footcite}. Finally, the page numbers in the index are
+% sorted properly: for example, two-digit numbers, like 81, are listed
+% before 123.
+%
+% \section{Refined use}
+% When references are made not only to modern authors but also to
+% authors and works from classical antiquity or from the Middle Ages,
+% it is commonly agreed that at least two separate indices of passages
+% cited should be made. Another option is not to index passages cited
+% from modern authors at all.
+%
+% \DescribeMacro{\IndexSubtypeAs} \package{icite} is able to
+% differentiate between sources by drawing from the bibliographical
+% database the exact string that may be found in the |entrysubtype|
+% entry field. To that end, the \cs{IndexSubtypeAs} command is
+% provided. It takes to mandatory arguments, like so:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \IndexSubtypeAs{<subtype>}{<index_name>}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% Where |<subtype>| is any given string used to specify an
+% |entrysubtype| in the bibliographical database, and |<index_name>|
+% the name of the index which the authors matching that subtype must
+% go into. This command is to be found in the preamble only.
+%
+% Of course different subtypes can be associated with a single index
+% or with different indices. That said, one should keep in mind that
+% any entry the actual subtype of which is not associated with an
+% index is processed as if it had no subtype at all. Examples
+% follow:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  % load icite, and have cited authors indexed in an index named
+  % 'secondary':
+  \usepackage[defaultindex=secondary]{icite}
+  % except for authors whose 'entrysubtype' field matches the string
+  % 'classical': have them indexed in an index named 'primary':
+  \IndexSubtypeAs{classical}{primary}
+  % authors whose 'entrysubtype' field matches the string 'medieval'
+  % should go into the same index:
+  \IndexSubtypeAs{medieval}{primary}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% Or:
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  % load icite, but do not index passages cited with \icite:
+  \usepackage[defaultindex=none]{icite}
+  % except for authors whose 'entrysubtype' field matches the string
+  % 'classical': have them indexed in an index named 'primary':
+  \IndexSubtypeAs{classical}{primary}
+  % authors whose 'entrysubtype' field matches the string 'medieval'
+  % should go into the same index:
+  \IndexSubtypeAs{medieval}{primary}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+%
+% \paragraph{Example} In the following example, modern authors, namely
+% those whose |entrysubtype| field does not match the string
+% |classical| should go into the default |loccit| index. As for those
+% whose |entrysubtype| matches |classical|, they should to into an
+% index named |primary|. Furthermore, the \package{classics} package
+% is used to format references in which a volume number is used. In
+% this way, \package{xindy} only has numbers to handle:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  % preamble
+  \usepackage[style=oxnotes]{biblatex}
+  \addbibresource{bibliography.bib}
+
+  \usepackage[xindy]{imakeidx}
+  \makeindex[name=loccit, title=Index of passages cited (modern authors)]
+  \makeindex[name=primary, title=\emph{Index locorum citatorum}]
+
+  \usepackage{classics}
+  \newclassic{iau}{\classicsRoman{#1}|, #1|.#1}
+  \newclassic{razi}{#1|.#1}
+  \newclassic{nadim}{\classicsRoman{#1}|.#1|, #1}
+  
+  \usepackage[citecmd=autocite,defaultindex]{icite}
+  \IndexSubtypeAs{classical}{primary}
+\end{code}
+% \iffalse
+%</example>
+% \fi
+% 
+% Then \cs{icite} can be used like so:--- %
+% \iffalse
+%<*example>
+% \fi
+\begin{code}
+  \section*{\cs{icite} in action}
+  Let us start with four citations of the same reference, to make sure

+% As already said above, all indices and the contents of the
