% BibTeX `apalike' bibliography style (version 0.99a, 8-Dec-10), adapted from
% the `alpha' style, version 0.99a; for BibTeX version 0.99a.

% Copyright (C) 1988, 2010 Oren Patashnik.
% Unlimited copying and redistribution of this file are permitted as long as

% are also permitted, but only if the resulting file is renamed.
%
% Differences between this style and `alpha' are generally heralded by a `%'.
% The file btxbst.doc has the documentation for alpha.bst.
%
% This style should be used with the `apalike' LaTeX style (apalike.sty).
% \cite's come out like "(Jones, 1986)" in the text but there are no labels
% in the bibliography, and something like "(1986)" comes out immediately
% after the author.  Author (and editor) names appear as last name, comma,
% initials.  A `year' field is required for every entry, and so is either
% an author (or in some cases, an editor) field or a key field.
%
% Editorial note:
% Many journals require a style like `apalike', but I strongly, strongly,
% strongly recommend that you not use it if you have a choice---use something
% like `plain' instead.  Mary-Claire van Leunen (A Handbook for Scholars,
% Knopf, 1979) argues convincingly that a style like `plain' encourages better
% writing than one like `apalike'.  Furthermore the strongest arguments for
% using an author-date style like `apalike'---that it's "the most practical"
% (The Chicago Manual of Style, University of Chicago Press, thirteenth
% edition, 1982, pages 400--401)---fall flat on their face with the new
% computer-typesetting technology.  For instance page 401 anachronistically
% states "The chief disadvantage of [a style like `plain'] is that additions
% or deletions cannot be made after the manuscript is typed without changing
% numbers in both text references and list."  LaTeX sidesteps the disadvantage.
%
% History:
%   15-sep-86  (OP)  Original version by Oren Patashnik, ideas from Susan King.
%   10-nov-86  (OP)  Truncated the sort.key$ string to the correct length
%                    in bib.sort.order to eliminate error message.
%   24-jan-88  (OP)  Updated for BibTeX version 0.99a, from alpha.bst 0.99a;
%                    apalike now sorts by author, then year, then title;
%                    THIS `apalike' VERSION DOES NOT WORK WITH BIBTEX 0.98i.
%    8-dec-10  (OP)  Still version 0.99a, as the code itself was unchanged;
%                    this release clarified the license.
