% chicago.sty: Style file for use with bibtex style chicago.bst, for

% bibliographies formatted according to the 13th Edition of the Chicago

% Manual of Style.

%

% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',

% with lots of tweaking to make it look like APA style, along with tips

% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.

% newapa.sty formed the basis of this style, chicago.sty. Author-date

% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst

% supports annotations.

%

% Version 4 (August, 1992):

% - fixed chicago.bst and chicagoa.bst to handle long author lists in

%   sorting

% - fixed chicago.bst and chicagoa.bst so that missing page numbers in

%   ``article'' entries are handled correctly

% - modified chicago.sty to format entries with 2nd and subsequent lines

%   indented.

%

%   Citation format: (author-last-name year)

%             (author-last-name and author-last-name year)

%             (author-last-name et al. year)

%             (author-last-name)

%             author-last-name

%             author-last-name (year)

%             (author-last-name and author-last-name)

%             (author-last-name et al.)

%             (year) or (year,year)

%             year or year,year

%

%   Reference list ordering: alphabetical by author or whatever passes

%    for author in the absence of one.

%

% This BibTeX style has support for abbreviated author lists and for

%    year-only citations.  This is done by having the citations

%    actually look like

%

%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}

%

% The LaTeX style has to have the following (or similar)

%

%     \let\@internalcite\cite

%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}

%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}

%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}

%     \def\shortciteA{\def\citeauthoryear##1##2##3{##2}\@internalcite}

%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}

%

% -------------------------------------------------------------------------

% This file implements citations for the ``chicago'' bibliography style.

%  Place it in a file called chicago.sty in the TeX search path.

%(Placing it in the same directory as the LaTeX document should also work.)

%

%    This file is a modification of the ``newapa'' LaTeX style,

%    originally adapted by Steven Spencer from the ``apalike'' LaTeX style.

%    It was originally modified by Stephen N. Spencer, with further

%    modifications by Young U. Ryu.

%

% The ``chicago'' BibTeX bibliography style creates citations with labels:

%       \citeauthoryear{author-info}{abbrev. author-info}{year}

%

% These labels are processed by the following LaTeX commands:

%

%  \cite{key}

%    which produces citations with full author list and year.

%    eg. (Brown 1978; Jarke, Turner, Stohl, et al. 1985)

%  \citeNP{key}

%    which produces citations with full author list and year, but without

%    enclosing parentheses:

%    eg. Brown 1978; Jarke, Turner and Stohl 1985

%  \citeA{key}

%    which produces citations with only the full author list.

%    eg. (Brown; Jarke, Turner and Stohl)

%  \citeANP{key}

%    which produces citations with only the full author list, without

%    parentheses eg. Brown; Jarke, Turner and Stohl

%  \citeN{key}

%    which produces citations with the full author list and year, but

%    can be used as nouns in a sentence; no parentheses appear around

%    the author names, but only around the year.

%      eg. Shneiderman (1978) states that......

%    \citeN should only be used for a single citation.

%  \shortcite{key}

%    which produces citations with abbreviated author list and year.

%  \shortciteNP{key}

%    which produces citations with abbreviated author list and year.

%  \shortciteA{key}

%    which produces only the abbreviated author list.

%  \shortciteANP{key}

%    which produces only the abbreviated author list.

%  \shortciteN{key}

%    which produces the abbreviated author list and year, with only the

%    year in parentheses. Use with only one citation.

%  \citeyear{key}

%    which produces the year information only, within parentheses.

%  \citeyearNP{key}

%    which produces the year information only.

%

% Abbreviated author lists use the ``et al.'' construct.

%

% `NP' means `no parentheses'.

%

% This LaTeX style file must be used with the ``chicago'' or ``chicagoa''

% (annotated chicago style) BibTeX styles.
