+%hum2.sty: Style file for use with bibtex style hum2.bst, for
+%bibliographies formatted according the handbook of the Modern Language
+%Association (MLA) and citations of the form footnote(Author, Title,
+%Page).  Repeated Author/Title will be replaced with Ibid.  In addition,
+%the article will be doublespaced and margins will be set to 1" standard.
+%
+%The following packages must be used in addition to hum2.sty:
+%	ifthen.sty
+%	doublespace2.sty
+%
+%This file is a jury-rig of the chicago bst and sty files.  It utilizes
+%the fact that chicago.bst passes two types of author fields to the
+%citation command:  full and abbreviated.  hum2 replaces the full author
+%field with the title (see below for important .bib note) and reformats
+%the \cite command (see the bottom of hum2.sty).
+%
+%IMPORTANT NOTICE
+%You must enclose your title in braces in your .bib file, ie,
+%	title = "{My Book of Computers}",
+%
+%IMPORTANT NOTICE
+%You need to replace (or start using) the command \note instead of \cite
+%(see next notice for format).
+%
+%IMPORTANT NOTICE
+%You must pass two commands to \note: first the page number and then the
+%citation key.  If you do not have a page number, give 'nopage' as the
+%first option, ie,
+%	So she said ``okay.''\cite{nopage}{aB99}  Then it
+%	hit\cite{pages~12--13}{cD88}.
+%
+%
+%Details:  it assumes you want a first page numbered 0.  Reset
+%counter page to 1 if this is not the case.  If all you want are the
+%citations, the important modifications are the first two lines (\cite
+%and \citeNP) and last three lines (\newcommand, \newboolean, and
+%\newcommand{\note}).  (In fact, I don't know everything that the rest
+%of the old chicago.sty file is doing, and didn't change it.)
+%
+%
+% THE FOLLOWING INFORMATION (between the lines) IS MOSTLY OUTDATED
+%  AND CONTAINS THE ORIGINAL chicago.sty DOCUMENTATION
+% ----------------------------------------------------------------------
+% 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.
