%%%%%%% BIBLIOGRAPHY %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% The following is to be used with pubsbib.bst (a slightly modified version
% of cslibib.bst, created by emma@csli.stanford.edu) or related bst
% files.  Designed to match selected Chicago-Manual-of-Style guidelines.
% At end of document where bibliography is to appear, put:
%
%	 \nocite{<declarations>}
%	 \bibliographystyle{pubsbib}
%	 \bibliography{<bibfile>}
%
% where <bibfile>.bib is your bibliography database file.
% 
%%%%%%%%%%%%%%%%%%%
% standard definition of \cite
% \def\cite{\@ifnextchar [{\@tempswatrue\@citex}{\@tempswafalse\@citex[]}}
%
% The revised \cite command takes advantage of the fact that
% pubsbib.bst gives \bibcite in the format
% \bibcite{labelname}{\citename{author }date}
% while the standard format is \bibcite{labelname}{label} 
\let\@internalcite\cite
\def\cite{\def\citename##1{##1}\@internalcite}

% \shortcite gives only the date (no parens)
\def\shortcite{\def\citename##1{}\@internalcite}

% \cite gives author date (no parens, no comma)
\def\@cite#1#2{{#1\if@tempswa ,\ #2\fi}}

% standard def for \@lbibitem
%\def\@lbibitem[#1]#2{\item[\@biblabel{#1}]\if@filesw 
%      { \def\protect##1{\string ##1\space}\immediate

%
% revised so no label is produced
\def\@lbibitem[#1]#2{\item[]\if@filesw

        \write\@auxout{\string\bibcite{#2}{#1}}}\fi\ignorespaces}

% (Note that the following commands apply to report or book style,
%  not to article style.)
% 
% The following could be used for setting up bibliographies at the end
% of each chapter in a collection of papers with separate
% bibliographies generated from a single .bib data-base.  At the end
% of each chapter, where the bibliography should appear, put the
% following:	 \chapbibliography{<database>}{<chapname>}{<bibstyle>}
% Then, run each chapter individually (using includeonly), doing
% bibtex immediately afterwards and renaming the resulting
% <jobname>.bbl file to be <chapname>.bbl.  Run again (some or all)
% to actually produce the bibliography.
% This may not work well with bib labels (e.g., numbers in square
% brackets) that change from chapter to chapter.  Better to use fixed
% labels (e.g., author-date, as in pubsbib style).

% The thebibliography environment executes the following commands:
%  \def\newblock{\hskip .11em plus .33em minus .07em} --
%      Defines the `closed' format, where the blocks (major units of 
%      information) of an entry run together.
%  \sloppy  -- Used because it's rather hard to do line breaks in 
%      bibliographies, 
%  \sfcode`\.=1000\relax --
%      Causes a `.' (period) not to produce an end-of-sentence space.
%
% The following assumes there will be no labels
% and there will be negative indentation.

% NOTE: the treatment of the year by \cite and \shortcite has been
% altered by changes to the following definition (the two occurrences
% of "purify$" have been deleted ... so that one can use hyphenated
% dates (etc) in the year field).  For the record (in case it causes
% problems), the old definition in pubsbib.bst was:
% 
% FUNCTION {calc.label}
% { type$ "book" =
%   type$ "inbook" =
%   or
%     'author.editor.key.label
%     { type$ "proceedings" =
% 	'editor.key.organization.label
% 	{ type$ "manual" =
% 	    'author.key.organization.label
% 	    'author.key.label
% 	  if$
% 	}
%       if$
%     }
%   if$
%   duplicate$
%   "\protect\citename{" swap$ * " }" *
%   year field.or.null purify$ *
%   'label :=
%   year field.or.null purify$ #-1 #4 substring$
