% Latex `lsalike' bibliography style (06-Jan-94 version 1.0alpha),
% This file implements citations for the ``lsalike'' bibliography style.
% It derives originally from `named', modified by a lot of people
% including someone at AAAI and Michael Braverman.
% This current version was rewritten by Dan Jurafsky, and
% is intended to roughly follow the LSA (Linguistic Society of America)
% style sheet.

% The ``lsalike'' bibliography style (lsalike.bst) creates citations 
% with labels like
%	 \citeauthoryear{author-info}{year}
% these labels are processed by the following commands:
%
%	\namecite[pageno]{key}
%		which produces citations with the author followed by the
%		year enclosed in parenthesis, e.g. Hemingway (1925).
%		Optional page number produces e.g. Hemingway (1925:135)
%	\cite[pageno]{key}
%		which produces citations with both author and year,
%		enclosed in parenthesis.
%		e.g. "(Barth 1968)"
%		Optional page number produces e.g. (Hemingway 1925:135)
%	\quotecite{key}
%		which produces citations with the author followed by
%		's and then the year enclosed in parenthesis.
%		e.g. "Chomsky's (1957) proposal met with little..."
%	\citeboth{key}
%		which produces citations with the author followed by the
%		name, no parenthesis.
%		e.g. "Barth 1968"
%	\citeauthor{key}
%		which produces the author information only
%		e.g. "Barth"
%	\citeyear{key}
%		which produces the year information only
%		e.g. "1947"

% lsalike currently uses the ampersand (&) instead of the
% word "and" in author lists, and it also replaces names by dashes in one
% more situation than the journal Language.
% Both these can be returned to standard Language style by switching the comments on
% the appropriate functions for \lsadashifynew  and \lsaand below.  
% (The non-standard situation occurs for ordered examples like:
%
% Robin, Christopher and Winnie Pooh
% Robin, Christopher and Eeyore
%
% The style will currently dashify the second Christopher Robin -
% this is not standard.
