% BibTeX `lsalike' bibliography style (06-Jan-94) % % Designed by Dan Jurafsky, modified from a version of `apalike.bst' augmented % by Michael Braverman. (The original header of `apalike' follows this one.) % Copyright (C) 1994, all rights reserved. % Copying of this file is allowed, provided that if you make any changes at all % you name it something other than `lsalike.bst'. % This style should be used with the lsalike.sty style file, % which generates citations like "Chomsky (1965)" or "Chomsky's (1965)" % The bibliography format follows the LSA style guide used for the journal % Language, except that it includes emphasis in more places than the vanilla LSA does, % does not put book titles in lower-case, uses ampersands % for "and" in places, and replaces names by dashes in one more % situation than LSA style does. These last two non-standard features % can be changed back to standard LSA style by changing lsalike.sty. % See the comment there. % % lsalike Editorial note: % Contrary to the opinions of the esteemed original authors, % (Susan King and Oren Patashnik) to whom, let me hasten to add, % we are all quite grateful, we DO recommend that you use a style % like lsalike. To correct a misrepresentation that appears below, % Mary-Claire van Leunen (A Handbook for Scholars, Knopf, 1979) % did NOT argue against a style like lsalike, but rather % against the traditional practice of including long bibliographic notes % directly in the text, or in footnotes. We agree. However, we believe % that the use of a work's author and year (as is common in linguistics) % rather than a `reference number' (which is common in computer science) % makes for much easier reading, and much less back-and-forth page-flipping. % Thus "Chomsky (1965) argued for the..." is every bit as elegant and % terse as "Chomsky [23] argued for the", and much more informative. % Similarly, "See Pollard and Sag (1987)" is much clearer than "See [55]", % or even "See [Pol87]". Use of a style like `plain' is extraordinarily % frustrating for the reader, especially in the social sciences, % which spend a great deal of time dealing with what everybody else said, % and in which, as in linguistics for example, everybody knows what % "Chomsky (1965)" said, but nobody can be expected to know % what "Chomsky [33]" said. % -Dan Jurafsky % % BibTeX `apalike' bibliography style (24-Jan-88 version) % Adapted from the `alpha' style, version 0.99a; for BibTeX version 0.99a. % Copyright (C) 1988, all rights reserved. % Copying of this file is allowed, provided that if you make any changes at all % you name it something other than `apalike.bst'. % This restriction helps ensure that all copies are identical. % 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 (SK,OP) Original version, by Susan King and Oren Patashnik. % 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.
