% apalike.sty style, used in conjunction with apalike.bst,
% will produce an apa-like bibliography style:
%
% 1) Bibliography entries formatted alphabetically, last name
%    first, each entry having a hanging indentation and no label.
% 2) References in the following formats:
%		(Author, 1986)
%		(Author and Author, 1986)
%		(Author et al., 1986).
% 3) Multiple references in the form (Author1, 1986; Author2, 1987)
%
% To be used as an optional argument to the \documentstyle command; for example
%	\documentstyle[11pt,apalike]{book}

% 16-Sep-86, original version by Susan King and Oren Patashnik.
% 13-Oct-87 changes:
%	Fixed bug in last line by adding the {} that disappeard when
%		the \hbox{} was removed from the pre-APALIKE definition;
%	added club and widow penalties;
%	patched the \newblock LaTeX bug from `-.07em' to simply `.07em';
%	and made this work for document styles that don't define `chapter'.
%
%
% Use parens instead of brackets for \cite, and no label in the bibliography
%

% Set length of hanging indentation for bibliography entries
