% \begin{abstract}
% This package typesets a listing of a (possibly large) \BibTeX{} input
% file. With old implementations of texmf the string space could easily be
% exceeded when trying to typeset large bibliographic databases.  Contemporary
% implementations are usually big and have much higher limits. However,
% \package{listbib} works with arbitrarily large \BibTeX\ database files.
%
% In addition to that, \package{listbib} tries to show the full content of a
% \BibTeX\ file without alterations introduced by the bibliographic style used.
% The entry fields ISBN, ISSN, annote, library, totalpages and URL are added to
% the standard ones.

%
% \section{History}
%
% This package is derived from |biblist|, version 1.4, 1992/01/13 by Joachim
% Schrod. J.\ Schrod's association with the university of Darmstadt seems to no
% longer exist. biblist is available from CTAN and is under the GNU general
% public license, version 1 or later.
% 
% \package{listbib} is the successor and will only work with \LaTeXe. 
% It uses the docstrip format for literate programming.
% The bibliography style was regenerated from btxbst.doc (unsrt), and
% then enhanced to be suitable for listbib. The fully commented |.bst| file is
% in the distribution (extension |.doc|).
%
% This documentation has little left of the original |biblist| documentation.
%
%
% \section{User manual}
%
% \subsection{Introduction}
%
% This package facilitates printing of large \BibTeX\ files. With  such
% large files --- especially if the cite keys are long --- the needed string
% space is often exceeded. Often a Big\TeX{} is available which pushes the
% limits further out, but with this package any \TeX{} will do it. Printing
% complete \BibTeX\ files as they are is useful for record-keeping.
%
% \DescribeEnv{thebibliography}
% The |\nocite{*}| command and |thebibliography| environment from \LaTeX\
% are used to do the work. The |thebibliography| environment is modified
% and eliminates huge |.aux| files and a second \LaTeX-run, although
% cross-references used in the bibliography entries themselves may still
% require a second \LaTeX-run.
%
% \DescribeMacro{\bibliography}
% A minimal \LaTeX-document must be prepared which uses the article class,
% loads the \package{listbib} package, and specifies the bibliography to be
% printed with the |\bibliography| command. Other packages can be loaded as
% well, for example to set margins or language-specific definitions.
%
% \DescribeMacro{\raggedbottom}
% Other classes can perhaps be used, but \package{listbib} works on the
% assumption that |\raggedbottom| is in effect, which is why it probably
% won't work too well with |twocolumn| or |multicol|. A page break within
% an entry is not allowed and the flexibility at the page bottom is needed.
%
% \DescribeMacro{\nocite}
% \DescribeMacro{\bibliographystyle}
% Unlike with normal \LaTeX\ documents, use of |\bibliographystyle| is not
% required, although it is not prohibited. The default is the listbib.bst
% bibliography style. It is also not necessary to use |\nocite{*}| as that is
% the default. However |\nocite| can be used to select certain entries only to
% be printed.
% 
% A ``bug'' you may encounter is that |\cite| tags within \BibTeX{} entries will
% not be processed. Instead the cite key itself will be printed. Note that this
% is not a bug, this is a feature! You have to use |\nocite| for \emph{all}
% entries that shall be included in the listing. If you do not give any
% |\nocite| tag at all, a listing with all entries is created.
% 
% \DescribeMacro{\BibTeX}
% As a bonus, \package{listbib} defines the control sequence |\BibTeX| if it
% is not already defined. The definition is copied from |btxdoc.tex|.
% 
%
% \subsection{Additional \BibTeX\ Entry Fields}
%
% In addition to the entry fields known by the standard \BibTeX\ styles,
% \package{listbib} recognises these fields: |ISBN|, |ISSN|, |annote|,
% |library|, |URL|, and |totalpages|.
% 
% The use of |ISBN| and |ISSN| should be obvious.
% 
% The |annote| field can be used for annotations or comments regarding this
% particular entry. The standard \BibTeX\ styles do not make use of this
% feature, however other styles might. With \package{listbib} it is useful to
% store a short summary of the contents of this entry. As for |note|, the
% first word should be capitalised. Punctuation at the end of the field 
% is added by the style if appropriate.
% 
% The |library| field is not meant to be printed in final documents, and is
% supplied to store e.g.\ the library location of a book. Useful for database
% listings only.
% 
% The |URL| field can be used to store a URL belonging to this bibliography
% entry. It is also becoming more popular to have bibliography entries which
% entirely consist of a URL. URLs are typeset as |\url{|\meta{URL}|}|, it is
% recommended to use package \package{url} with documents referencing
% bibliography entries which contain a URL. As an additional safeguard, the
% listbib \BibTeX-style defines |\url| to exand to \meta{URL} if it is not
% already defined. This field is supported by \package{custom-bib}.
% 
% The |totalpages| field is meant to store the total number of pages of the
% work. This field is supported by \package{custom-bib}.
%
% All 13 entry types take the |library|, |annote|, |totalpages| and |URL|
% fields. They take the fields |ISBN| and |ISSN| as well, with these exceptions:
% |article| only takes |ISSN|, and |unpublished| takes neither |ISBN| nor |ISSN|.
%
%
% \subsection{Formatting of the entries in the resulting listing}
%
% \begin{description}
% \item[\tt cite key]
%   \leavevmode \null \dotfill \quad {\sf\small (Library info)}\break
% Author(s)/Editor(s).\\
% {\em Title.}\\
% Publication info.\\
% Notes.\\
% \null \qquad {\footnotesize Pages: 123 \ensuremath{\bullet}
%                 URL: \texttt{http://my.url/file}}\\
% \null \qquad {\footnotesize Annotation}
% \end{description}
%
% I.e., an open format is used. Although this needs more space I think the
% enhanced legibility pays back.
%
% Note that you will not get the `Library info' and the `Annotation' in the
% above format if you use a bibliography style other than |listbib| which
% does not supply this information with the assumed markup. The parenthesis
% around the library info are produced by this style option, not by \BibTeX.
%

% Of course, the ISBN/ISSN numbers, annotations, and library information is

% 
% 
% \subsection{Site Configuration File}
% 
% The \package{listbib} package will input a site configuration file
% \DescribeWord{listbib.cfg}
% |listbib.cfg| if it exists. This is a good place for changing margins or the
% document title, etc. The configuration file is |\input| at the end of the
% \package{listbib} package.
% Here is an example:
% \begin{quote}
% \begin{verbatim}
%   %% listbib.cfg     VK 30 Jul 2000
% 
%   % Date format: 99 Month 9999
%   \newcommand\monthname{%
%     \ifcase \month \or
%       January\or February\or March\or April\or May\or June\or
%       July\or August\or September\or October\or November\or December\fi
%   }
%   \def\today{%
%     \number\day \space \monthname \space \number\year
%   }
% 
%   % Latin-1 input
%   % (There is currently no way to do this from within a .bib file.)
%   \usepackage[latin1]{inputenc}
% \end{verbatim}\fixendverbatim
% \end{quote}
% 
% 
% \subsection{Inheriting Field Entries}
% 
% As \BibTeX\ currently works, missing fields in all entries which
% crossreference another entry are inherited from the crossreferenced entry. To
% illustrate, in this .bib file
% 
% \begin{quote}
% \begin{verbatim}
%   @incollection{chapter,
%       crossref="book",
%       author="..", title=".."
%   }
%   @book{book,
%       editor="..", booktitle="..", note=".."
%   }
% \end{verbatim}\fixendverbatim
% \end{quote}
% 
% the chapter entry inherits the |note| field from the |book| entry. The same is
% true for all other fields which can possibly be inherited. \BibTeX\ does not
% make the information of whether a field was inherited available in the style
% file, so the inheritence can not be detected directly.
% 
% \package{listbib} implements a workaround for this which can detect inherited
% fields. A field is assumed to be inherited by a crossreferencing entry  if its
% value is identical to that of the crossreferenced entry. This assumption fails
% when the field values are in fact identical. Please let me know of any cases
% where that is a problem, and I will try and fix it or make a sepaarte style
% which does not try to detect inherited fields. A quick fix might be to add
% something like a |{}| at the end of the field.
% 
% Currently inheritance is detected for the fields |note|, |annote|, |ISBN|,
% |ISSN|, |library|, |totalpages| and |URL|. Inherited fields are not printed in
% the listing.
% 
% 
% \subsection{The listbib.tex Main Document Frame}
% 
% \DescribeMacro{\listbibs}
% The shortest way to to typeset a bibliography is to put something like this
% into a \meta{file}|.tex| and to run it through \LaTeX, \BibTeX, and (possibly
% more than once) \LaTeX\ again:
%     \begin{quote}
%     |\newcommand||\listbibs||{|\meta{bibliographies}|}|\\
%     |\AtBeginDocument{|\meta{preamblematerial}|}|\\
%     |\input||{||listbib||}|
%     \end{quote}
% For \meta{bibliographies} list everything to be printed. Any \BibTeX\
% files containing string definitions must also be specified (first).
%
% \DescribeMacro{\AtBeginDocument}
% The use of |\AtBeginDocument| is completely optional. If used,
% \meta{preamblematerial} will be inserted into the preamble of
% |listbib.tex|.
% 
% |listbib.tex| also loads the packages
%   \DescribeWord{vmargin}
%   \DescribeWord{url}
% \package{vmargin} and \package{url} if
% it can find them. \package{vmargin} sets up the page margins, and
% \package{url} provides a |\url| command for typesetting urls.
% 
% A configuration file \meta{file}|.cfg| will be loaded within the preamble of
% |listbib.tex|, if it exists.
%

% \subsection{The listbib Shell Script}
%
% The |listbib| program can be used to quickly generate a listing of the
% bibliographies given on the command line. The program is a Unix shell script;
% sorry if you don't use Unix. You may still be able to port it, send me a copy
% if you do.
% 
% Here is its usage:
% \begin{verbatim}
%   Usage: listbib [OPTIONS] [BIBFILE[.bib] ..] BIBFILE_N[.bib]
%   Version VK 1.2.3, 28 Aug 2000
% 
%   Options:
%     -h|--help              shows help
%     -o|--output FILE       generates FILE.dvi / FILE.ps (default listedbibs)
%     -O|--same              as -o, but generate FILE.dvi and BIBFILE_N.ps
%     -p|--ps|--postscript   generate PostScript as well as dvi
%     -d|--deltemp           delete all generated files but .dvi
%     -P|--psonly            generate only PostScript (delete all generated files
%                              but .ps)
%     --                     stop option processing; only .bib files remain
% \end{verbatim}\fixendverbatim
% A temporary .tex file is created which makes use of |listbib.tex|. latex,
% bibtex, and possibly dvips are run on the .tex file to create the listing of
% all .bib files specified. The .bib extension can be left out. Remember to
% specify any .bib first which define any strings needed later.
% 
% By default, the name of the .tex file is |listedbibs.tex|, this can be changed
% with the |-o| option. Don't specify an extension here.
% 
% To generate PostScript as well, use the |-p| option. This currently only
% supports dvips. I can change that if there is demand. The |-d| option will
% delete all temporary files when |listbib| is finished, and only leave the dvi
% file. |-P| will create a PostScript file and then delete all others.
%
% To only generate a mybib.ps from mybib.bib, use |-P -O|.
% 
% An error is displayed if the .tex file to be created already exists and is not
% one generated by listbib.
%
%
% \subsection{To Do and Bugs}
% 
% Inheritance is currently only checked for the fields |note|, |annote|, |ISBN|,
% |ISSN|, |library|, |totalpages| and |URL|. Printing of these fields is
% suppressed for all entry types if inherited. Should printing of other
% inherited fields be suppressed as well? I am less inclined to suppress
% |volume|, and I am not sure about |year|, |month|, etc. Please let me know
% what you think.
% 
% As a future enhancement one could place a word from the starting and the
% finishing entry on each page into the page header, like it is in a dictionary.
% 
% Some kind of section title above each .bib file would be useful.

%
%
% \subsection{Preliminary}
%
%    \begin{macrocode}
%&lt;*package&gt;
%    \end{macrocode}
%
% The main work is to supply the environment |thebibliography|; in
% fact, we implement it as a |description| environment. The environment
% has an unused argument. In addition we have to supply a correct
% definition for the |\bibitem| command which takes the cite key as its
% argument. Of course, this will result in an |\item|. After the
% |\bibitem| a |\library| tag may follow, with one parameter followed
% by a period. Then comes the reference, the (optional) annotation is
% a block of its own, enclosed in |\annote| and |\endannote|. After
% |\endannote| comes a period which should be discarded. (This should
% be done in the \BibTeX{} style, but nevertheless\dots)
%
% Before we start we declare some shorthands for category codes.
% By declaring the underscore~`(|_|)' as letter we can use it in our
% macros. (I agree with {\sc D.~Knuth} that
% |\identifier_several_words_long| is more readable than
% |\IdentifierSeveralWordsLong| and in every case better than
% |\p@@@s|.) As this is a \LaTeX{} style option the at sign is a letter
% anyhow; so we can use the ``private'' Plain and \LaTeX{} macros; and
% with the underscore we can make our own macros more readable.  But as
% we have to restore this category code at the end of this macro file
% we store its former value in the control sequence |\uscode|. This
% method is better than using a group because not all macros have to
% be defined global this way.
%
%    \begin{macrocode}
\chardef\uscode=\catcode`\_
\catcode`\_=11
%    \end{macrocode}
%
%
% \subsection{The Bibliography}
%
% \begin{environment}{thebibliography}
% Within an entry we use a ragged right margin. To break within an
% entry is always difficult and is made easier in this way. After all,
% the open format we use gives a ragged impression anyhow. Within an
% entry we dissallow page breaks and we do not treat periods as full
% stops.
%
%    \begin{macrocode}
\def\thebibliography#1{%
    \description
        \rightskip \z@ plus 2em
        \interlinepenalty\@M
        \sfcode`\.=\@m
    }
\let\endthebibliography=\enddescription
%    \end{macrocode}
% \end{environment}
%
% |\bibitem| should look for the next token: If a library info
% exists it must go in the same line, otherwise a line break must be
% issued.
%
% \begin{macro}{\@lbibitem}
% \begin{macro}{\@bibitem}
% But |\bibitem| itself is not of interest, it looks only for the
% optional argument. We have to redefine |\@bibitem|. If a
% bibliography style like |alpha| is used, |\bibitem| will be supplied with
% an optional argument. We ignore this optional argument.
%
% After the argument(s) of |\bibitem| a line end occurs in any case. The
% optional |\library| tag will follow on the next line. This means we
% first have to gobble the line end char |^^M|, and have to check the
% next token afterwards. If this next token is |\library| we will do
% nothing since |\library| will itself end the line. Otherwise we do a
% line break. Experiments have shown that the dotted line at the start
% of every entry helps with finding the different entries.
%
%    \begin{macrocode}
\def\@lbibitem[#1]{\@bibitem}
\def\@bibitem#1{%
    \item[\texttt{\lb_sanitize{#1}}]\leavevmode

    \expandafter\string\csname#1\endcsname}}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
%
% \subsection{Library}
%
% \begin{macro}{\library}
% We assume that the library info and the cite key will fit into
% one line. If this is not true, a two line solution would have to be set up.
%
% We add |\@highpenalty| instead of |\@M| after the library part to avoid 
% an underfull hbox warning and an empty line if both author and editor are
% empty (in which case there is a |\newblock| immediately following the 
% |\library{..}|. Alternativelly, we could implement more |\futurelet|
% trickery.
%
%    \begin{macrocode}
\def\library#1{%
    \quad\textsf{\small (#1)}\penalty -\@highpenalty
    }
%    \end{macrocode}
% \end{macro}
%
%
% \subsection{Annotation}
%
% \begin{macro}{\newblock}
% A reference is divided into blocks starting with |\newblock|.
% Each block shall start a new line. We use |\newline| for this. A
% special block is the one with an annotation in it. Since we want to
% indent this block once more we must change the parshape. But then we
% have to finish the paragraph first. The annotation block starts with
% |\annote| and may be easily recognized in this way.
%
%    \begin{macrocode}
\def\newblock{%
    \futurelet\next\@checkAnnote
    }
\def\@checkAnnote{%
    \ifx \next\annote \else \newline \fi
    }
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\annote}
% The annotation is a paragraph on its own and indented by |\leftmargin|.
% Since it is not a paragraph in the logical sense we do not insert
% vertical glue (i.e., |\parskip|) at the top. The annotation is typeset
% in a smaller size. We assume that it consists of full sentences which
% might be made up in a proper way. Therefore we don't use a ragged
% margin here.
%
% The change of |\parshape| has to be reset after the group --- these
% changes are not local.
%
%    \begin{macrocode}
\def\annote{%
    \endgraf
    \vskip -\parsep
    \begingroup
        \reset@font\footnotesize
        \rightskip\z@skip
        \advance\linewidth -\leftmargin
        \advance\@totalleftmargin \leftmargin
        \parshape \@ne \@totalleftmargin \linewidth
    }
%    \end{macrocode}

%
%
% \subsection{Citation Key}
%
% \begin{macro}{\@citex}
% In our documents |\cite| will print the cite key in typewriter with a framed
% box around. In fact, |\cite| expands to |\@citex|, which has an optional
% argument. The flag |\if@tempswa| shows if this optional argument is there.
% |\texttt{..}| will alter |\if@tempswa|. So might |\fbox| and |\ttfamily| in
% the future. |\fbox| does not work inside |\if|, and |\lb_sanitize|
% does not work inside a |\def|, so we save the flag in |\@cxt|.
%
% ^^A &gt; \cite=macro:
% ^^A -&gt;\protect \cite  .
% ^^A &gt; \cite =\long macro:
% ^^A -&gt;\@ifnextchar [{\@tempswatrue \@citex }{\@tempswafalse \@citex []}.

% comma is removed after the loop. When there was no file name
% |\bib_list| will expand to an empty list, the |\relax| serves as a
% catch-argument for |\@gobble|.
% 
% A |.bib| is no longer added to each bibliography filename to make the line
% shorter. If there are too many names the header won't fit on the page. This
