%\section{Introduction}
%\label{sec:intro}
%
% The list of cited works accompanying a scholarly work is not just
% a technical appendix or a subtle way to avoid accusations of
% plagiarism.  Rather, it is an organic part of the work, telling the
% user a story about the field of study and showing why the given
% work is an organic part of it.  There are several ways to tell the
% story, and accordingly there are several ways to organize the list
% of references.  One can tell it accordingly to logical
% development of ideas, so the order of citations follows the order
% they are mentioned in the paper.  This leads to the ``unsorted''
% style of references, usual in physics and mathematics papers and books.
% Alternatively, one can choose to tell the story as the story of
% people behind the ideas, ordering the citations alphabetically by
% author names.  This is the order used in humanities and other fields.
% Yet another possibility is to tell the story in the chronological
% order.  The chronological order of citations is not widely used,
% with the important exception of resumes and CVs, but it has its own
% advantages.  
%
% In the times BC (Before Computers), difficulties in manual creation
% of reference lists discouraged presentation of more than one such
% list.  Now we can easily have as many lists as we want.  Accordingly
% we can have not one, but several lists of references, each telling a
% different story.  The package
% |multibibliography|~\cite{Multibibliography, Multibibliography13}
% provided just this: multiple bibliographies with the same references arranged
% in different orders, with hyperlinks between entries.  However, this
% package had various limitations, including: the fixed format of
% typesetting citations in text, the limitation on the possible
% Bib\TeX\ styles.  Also, it requires post-processing by a Perl
% script.
%
% This package tries to lift these limitations.  It provides the
% following improvements over the original |multibiliography|:
% \begin{enumerate}
% \item A Perl postprocessing is no longer needed:  all processing is done
% by Bib\TeX.
% \item The user can work with familiar |natbib|~\cite{Daly:Natbib}
%   commands \cs{citep}, \cs{citet}, \cs{citeauthor}, \cs{citeyear},
%   \cs{citenum}. 
% \item Any |natbib|-compatible |.bst| file can be used for formatting
% the bibliography provided that it has the right sorting of entries
% (note that the provided style gives |natbib|-compatible
% chronological ordering).
% \item The style is much more customizable than that produced by
% |multibibliography|.  
% \item Hyperlinks between the entries are improved.
% \end{enumerate}
% 
% Note about the name.  The letter \emph{n} in the package name can be
% interpreted as
% \begin{enumerate}
% \item \emph{N}ew multibibliography style, or
% \item \emph{N}atbib-compatible multibibliography style, or even
% \item \emph{N}-ordering multibibliography style, with $N$ being a
% usual mathematical moniker for ``many''.
% \end{enumerate}
% 
%
%\section{User Guide}
%\label{sec:ug}
%
%
%\subsection{Usage Summary}
%\label{sec:ug_usage}
%
% The simplest way to use the package is the following:
% \begin{enumerate}
% \item Add to the preamble of your |.tex| file
% \begin{verbatim}
% \usepackage{nmbib}
% \multibibliography{FILE1, FILE2, ...}
% \multibibliographystyle{timeline}{STYLE1}
% \multibibliographystyle{sequence}{STYLE2}
% \multibibliographystyle{authors}{STYLE3}
% \end{verbatim}
% 
% \item Use |natbib| commands such as |\cite|, |\citep|, |\citet|,
%   |\citeauthor|, |\citeyear|, and |\citenum|.  The command |\citeall|
%   creates a ``full citation'', showing the author,  year, and 
%   number of the citation.
% \item Put in your document at the places where you want the
%   bibliography the commands |\printbibliography{timeline}|,
%   |\printbibliography{sequence}|, and |\printbibliography{authors}|.
% 
% \item Run |latex| on the |tex| file.  This will create, besides the
% standard auxiliary file |FILE.aux|, three new files:
% |FILE-timeline.aux|, |FILE-sequence.aux| and |FILE-authors.aux|.
% \item Run |bibtex| on each of the three auxiliary files mentioned
%   above:
% \begin{verbatim}
% bibtex FILE-timeline
% bibtex FILE-sequence
% bibtex FILE-authors
% \end{verbatim}
% \item Run |latex| on the |tex| file at least twice (this is a
% |natbib| requirement).
% \end{enumerate}
% 
% Below we discuss these commands in more detail as well as
% customization commands.
%
%
%\subsection{Options}
%\label{sec:ug_options}
%
% The |nmbib| package internally uses |natbib| \cite{Daly:Natbib} for citation
% formatting.  The options used for |nmbib| are sent to |natbib|.
%
%\subsection{Setting up}
%\label{sec:ug_setting}
% 
% \DescribeMacro{\multibibliography}%
% The list of \BibTeX\ databases to be used for references is set by
% the command \cs{multibibliography}\marg{bibfile1, bibfile2, \dots}.
% Note that the similar command \cs{bibliography} in standard
% \LaTeX\ performs \emph{two} functions:
% it sets up the databases and prints the
% bibliography.  The command \cs{multibibliography}, on the other
% hand, performs only one function: the setting up of the databases.
% The bibliographies themselves are printed by the command
% \cs{printbibliography}, discussed below.  Therefore the \cs{multibibliography} command
% can be issued anywhere in the file, including
% the preamble. 
%
% \DescribeMacro{\multibibliographystyle}
% The standard \cs{bibliographystyle} command sets the bibliography
% style of the reference list.  Since |nmbib| generates several
% bibliographies, the corresponding command is more versatile:
% \cs{multibibliographystyle}\marg{type}\marg{style},
% where |type| is the type of the bibliography
% \begin{description}
% \item[timeline:] Chronologically ordered list.
% \item[sequence:] Sequentially ordered list.
% \item[authors:] Alphabetic list, ordered according to 
% authors' names.
% \end{description}
% and \marg{style} is the corresponding \BibTeX\ style.  The style, of
% course, must sort the entries in the proper order.
%
% The package can accommodate any |natbib| \BibTeX\ style,
% including |unsrtnat|, |plainnat|, and |abbrvnat|.  It may work with other
% styles, but success is not guaranteed.  The \BibTeX\ styles
% supplied with the package offer additional hyperlink features;  if
% you do not use |hyperref| or do not care for the links between the
% different reference lists, you probably do not need these features.  
% 
% There are three citation styles provided with the package:
% \begin{description}
% \item[chronoplainnm:] Similar to |plainnat|, but sorting
% entries in chronological order (using year, month and day if the
% latter two are available) and providing links to other lists from the
% body of the entries.
% \item[plainnm:] Similar to |plainnat|, but providing links to other
%   lists from the body of the entries.  The sorting is alphabetical
%   by authors' names, as in |plainnat|.
% \item[unsrtnm:] Similar to |unsrtnat|, but providing links to other
%   lists from the body of the entries.  The order of entries is the
%   order of citations, as in |unsrtnat|.
% \end{description}
% 
%
%\subsection{Citation commands}
%\label{sec:ug_commands}
%
% All citations commands defined in |natbib| can be used: \cs{cite},
% \cs{citenum}, \cs{citealt}, \cs{citet}, \cs{Citet}, etc.  The |nmbib| package
% adds a couple of new commands, described here.
%
% \DescribeMacro{\citealn}%
% The commands \cs{citealn}\marg{keys} is the alternative \cs{citenum}
% command:  it puts square brackets around its argument.
%
% \DescribeMacro{\citeall}%
% The command \cs{citeall}\marg{keys} produces citations with
% authors' names, years, and sequence numbers, similar to that
% produced by the \cs{cite} command in the |multibibliography| package.
% To reproduce the behavior of that package, just put in
% the preamble of your document
% \begin{verbatim}
% \let\cite\citeall
% \end{verbatim}
%
% The starred command \cs{citeall*} is similar to \cs{citeall} with
% the following difference: if \cs{citeall} prints the shortened author
% list for papers with multiple authors (``Jones et.\ al.''),
% \cs{citeall*} prints the full list (``Jones, Smith, and Brown'').   
%
%
%\subsection{Printing the bibliographies}
%\label{sec:ug_print}
%
%
% \DescribeMacro{\printbibliography}%
% The command \cs{printbibliography}\marg{type} prints the
% bibliography.  The argument is the type of bibliography---
% |timeline|, |sequence|, or |authors| (see the explanation above).
% 
%
%  You can put this command anywhere in your file;  the corresponding
%  bibliography will be printed in this place.  You can use all three
%  possible lists, any two, or even one.  The only limitation is
%  that the ``base type'' list must be included.
% (See Section~\ref{sec:ug_customization} for the discussion of base type.)
%
%
%\subsection{Hyperlinks}
%\label{sec:ug_hyperlinks}
%
% The |nmbib| package tries to fully exploit features of |hyperref| package
% \cite{Rahtz:Hyperref}.  Links from and between
% citations should work ``smartly'':  links from authors' names go
% into the alphabetic list, links from the publication years go into the
% chronological list, and links from the citation numbers go into the
% sequential list.  
%
% \DescribeMacro{\nmbibRedirectLinks}%
% Of course, the user might include only some of the three possible
% lists.  In this case some links become ``dangling.''  The command
% \cs{nmbibRedirectLinks}\penalty0\marg{source\_type}%
% \penalty0\marg{target\_type} redirects the links that otherwise go to
% the list \marg{source\_type} to the list \marg{source\_type}.  For
% example, if a chronological list is not included, the
% command |\nmbibRedirectLinks{timeline}{authors}| makes the links
% from the publication year go into the alphabetical list of
% publications.
%
% \DescribeMacro{\nmbibLink}%
% The clickable links themselves are created with the help of the
% command \cs{nmbibLink}\marg{citation}\marg{type}\marg{text}.  This
% command is available to the user, which enables constructions like
% \begin{verbatim}
% The idea was proposed by \citet{Thor10}.   Note the assumption of 
% differentiability in \nmbibLink{Thor10}{authors}{his paper}.  
% \end{verbatim}
% In this example ``his paper'' becomes a hyperlink to the paper in
% the alphabetical list.  
%
% The links created with \cs{nmbibLink} respect the redirections set
% by the command \cs{nmbibRedirectLinks}.
% 
%
%\subsection{Advanced customization}
%\label{sec:ug_customization}
%
% \DescribeMacro{\timelinerefname}%
% \DescribeMacro{\sequencerefname}%
% \DescribeMacro{\authorsrefname}%
% \DescribeMacro{\timelinebibname}%
% \DescribeMacro{\sequencebibname}%
% \DescribeMacro{\authorsbibname}%
% The commands \cs{refname} (for article-like classes) and
% \cs{bibname} (for book-like classes) retain the names of the
% bibliography.  The |nmbib| package defines three macros |\TYPErefname| and
% three commands |\TYPEbibname|, |TYPE| being |timeline|, |sequence|,
% or |authors|.  These macros can be redefined with the usual
% \cs{renewcommand}.
% For example, for a German article, one might use
% \begin{verbatim}
% \renewcommand{\timelinerefname}{Chronologische Referenzliste}
% \renewcommand{\sequencerefname}{Sequenzielle Referenzliste}
% \renewcommand{\authorsrefname}{Alphabetische Referenzliste}
% \end{verbatim}
%
% 
%
% \DescribeMacro{\multibibliographyfilename}
% By default the package creates three auxillary files with the
% following file names:  |FILE-timeline.aux|,
% |FILE-sequence.aux|, and |FILE-authors.aux|.  The command
% \cs{multibibliograpyfilename}\marg{type}\marg{name} changes this
% default.  Here \marg{type} is |timeline|, |sequence|, or |authors|, and
% \marg{name} is the file name.  The default setting is equivalent to
% \begin{verbatim}
% \multibibliograpyfilename{timeline}{\jobname-timeline}
% \multibibliograpyfilename{sequence}{\jobname-sequence}
% \multibibliograpyfilename{authors}{\jobname-authors}
% \end{verbatim}
% This command may be present only in the preamble of a document.
%
%
% 
% \DescribeMacro{\nmbibBasetype}%
% Suppose an author published several works in the same year.  They
% need to be distinguished in the text and bibliography.  In the
% standard author-year styles this is done by adding a suffix after
% the year: if we want to cite three works by A.\,U.\ Thor published
% in 2013, they are respectively cited as Thor~(2013a), Thor~(2013b), and
% Thor~(2013c).  When we have only one reference list,
% the choice of suffixes is simple: the first work becomes 2013a, the
% second 2013b, etc.  But how should we deal with the situation of
% several subbibliographies?  The order of these references in different
% lists could be different, so the same work could get different labels in
% different lists.
%
% To prevent this confusion, only one reference list is used to
% construct the labels.  We call the corresponding list type the
% \emph{base type}.  By default it is |sequence|, but this might be
% changed (and should be chaged if the user does not include
% sequential list) with the command \cs{nmbibBasetype}\marg{type}, with
% \marg{type} being |timeline|, |sequence|, or |authors|.  The list
% chosen as a base type must be included with the
% \cs{printbibliography} macro.
%
% Package |natbib| defines citation aliases:  you can use ``Paper~I''
% or ``Paper~II'' as aliases for some papers.  Normally hyperlinks
% from aliases go into the alphabetic list;  however, you can change
% it with the special type |alias| in \cs{nmbibRedirectLinks}, for
% example,
% \begin{verbatim}
% \nmbibRedirectLinks{alias}{timeline}
% \end{verbatim}
%
%
% 
% \DescribeMacro{\nmbibSetCiteall}%
% The format of the \cs{citeall} and \cs{citeall*} macros can be
% changed by the command \cs{nmbibSetCiteall}\marg{pattern}, where
% \marg{pattern} sets the citation format.  The pattern can use any
% punctuation, \cs{nmbibLink} command and the special tokens
% \cs{nmbibKEY}, \cs{nmbibNAME}, \cs{nmbibDATE} and \cs{nmbibNUM},
% which are substituted by the citation information.  For example, the
% default format is established by the command
% \begin{verbatim}
% \nmbibSetCiteall{\nmbibLink{\nmbibKEY}{authors}{\nmbibNAME} 
%  (\nmbibLink{\nmbibKEY}{timeline}{\nmbibDATE}) 
%  [\nmbibLink{\nmbibKEY}{sequence}{\nmbibNUM}]}
% \end{verbatim}
% which produces the following result: \citeall{Daly:Natbib}.  
%
% \DescribeMacro{\nmbibSetBiblabel}%
% The command \cs{nmbibSetBiblabel}\marg{type}{pattern} is used to set
% the format of the label in the reference list of the given type.
% The \marg{pattern} parameter uses the same tokens as \cs{nmbibSetCiteall}.
% The default is
% \begin{verbatim}
%\nmbibSetBiblabel{timeline}{[\nmbibDATE: 
%  \nmbibLink{\nmbibKEY}{authors}{\nmbibNAME}; 
%  \nmbibLink{\nmbibKEY}{sequence}{\nmbibNUM}]}
%\nmbibSetBiblabel{authors}{[\nmbibNAME\  
%  (\nmbibLink{\nmbibKEY}{timeline}{\nmbibDATE}); 
%  \nmbibLink{\nmbibKEY}{sequence}{\nmbibNUM}]}
%\nmbibSetBiblabel{sequence}{[\nmbibNUM: 
%  \nmbibLink{\nmbibKEY}{authors}{\nmbibNAME}
%  (\nmbibLink{\nmbibKEY}{timeline}{\nmbibDATE})]}
% \end{verbatim}
% To suppress the label for any type, use an empty pattern:
% |\nmbibSetBiblabel{authors}{}|.  To use numerical labels only for a
% sequential list, issue |\nmbibSetBiblabel{sequence}{[\nmbibNUM]}|
% etc. 
%
% \DescribeMacro{nmbibYearSuffixOff}%
% \DescribeMacro{nmbibYearSuffixOn}%
% If there are several works with the same authors and year, the
% package adds suffixes to the year numbers, like 2003a and 2003b.  By
% default these suffixes are printed both in the labels \emph{and} in
% the bibliographic entries themselves.  The command
% \cs{nmbibYearSuffixOff} deletes these suffixes from the bibliography
% entries (but not from labels).  The command \cs{nmbibYearSuffixOff}
% restores them.
% 
%
%\subsection{Auxillary script}
%\label{sec:script}
%
% To integrate the package with IDEs like \TeX Shop, we provide a
% simple script |nmbibtex| which compiles all bibliographies.  Its
% usage is very simple:
% \begin{verbatim}
% nmbibtex FILE
% \end{verbatim}
% where |FILE| is the file name without prefixes.
