A number of contributed packages exist to accommodate this % citation mode, but each one is tailored to a limited number of \btx\ style % (\texttt{.bst} files. The reason is that each one reads in the author--year % information in different formats for the |\bibitem| commands. % In contrast, % the \thestyle{} package supports not only the various author--year % bibliography styles, but also those for standard numerical citations. In % fact, it can also produce numerical citations even with an author--year % bibliographic style, something that permits easy switching between the % two citation modes. To this end, replacements for the standard % \LaTeX\ \texttt{.bst} files are also provided. % % It is possible to define the citation \emph{style} (type of brackets and % punctuation between citations) and even to associate it with the name of the % bibliographic style so that it is automatically activated. Citation styles % can be defined for local \texttt{.bst} files by means of a configuration file % \thestyle\texttt{.cfg}. % % It is compatible with the packages: \texttt{index}, \texttt{showkeys}, % \texttt{chapterbib}, \texttt{hyperref}, % and with the classes \texttt{amsbook} and % \texttt{amsart}. It can also emulate the sorting and compressing % functions of the \texttt{cite} package (with which it is otherwise % incompatible). % % The \thestyle\ package therefore acts as a single, flexible interface for % most of the available bibliographic styles. % % \end{abstract} % % \section{Introduction} % The first problem of using author--year literature citations with standard % \LaTeX{} is that the two forms of citations are not supported. These are: % \begin{quote} % textual: \dots\ as shown by Jones et al. (1990) \dots\\ % parenthetical: It has been shown (Jones et al., 1990) that \dots % \end{quote} % There is only one |\cite| command to do both jobs. % % A second problem is that the \texttt{thebibliography} environment for % listing the references insists on including the {\em labels\/} in the % list. These labels are normally the numbers, needed for referencing. In % the author--year system, they are superfluous and should be left off. % Thus, if one were to make up a bibliography with the author--year as % label, as % \begin{quote} % \begin{verbatim} % \begin{thebibliography}{...} % \bibitem[Jones et al., 1990]{jon90} % Jones, P. K., . . . % \end{thebibliography} % \end{verbatim} % \end{quote} % then |\cite{jon90}| produces the parenthetical citation [Jones et al., % 1990], but there is no way to get the textual citation. Furthermore, % the citation text will also be included in the list of references. % % The final problem is to find a \btx{} bibliography style that will be % suitable. % % \section{Previous Solutions} % \begin{quote}\slshape % This section may not be of interest to all users. To find out how to use % \thestyle\ without reading about the historical background, go to % Section~\ref{sec:usage}. % \end{quote} % % Although the author--year citation mode is not supported by % \emph{standard} \LaTeX, there are a number of contributed packages that % try to solve this problem. The various bibliographic styles % (\texttt{.bst} files) that exist are usually tailored to be used with a % particular \LaTeX{} package. % % I have found a large number of \texttt{.bst} files on file servers that may % act as indicators of the various systems available. % % \subsection{The \texttt{natsci.bst} Style} % What gave me my first inspiration was Stephen Gildea's \texttt{natsci.bst} % for use with his \texttt{agujgr.sty} file. This showed me that the problem % was solvable. However, Gildea's style formats |\bibitem| just as I % illustrated above: with an optional label consisting of abbreviated % authors and year. Thus only parenthetical citations can be accommodated. % The list of references, however, is fixed up in his style files. % % \subsection{The \texttt{apalike.bst} Style} % Oren Patashnik, the originator of \btx{} and the standard \texttt{.bst} % files, has also worked on an author--year style, called \texttt{apalike.bst} % with a corresponding \texttt{apalike.sty} to support it. Again, only the % parenthetical citation is provided. Except for the fact that his style % works with version~0.99 of \btx, its functionality is identical to that % of the \texttt{natsci} files. % % Patashnik does not like author--year citations. He makes this very clear % in his \btx{} manuals and in the header to \texttt{apalike.bst}. % Nevertheless, one should respect his work in this area, simply because he % should be the best expert on matters of \btx. Thus \texttt{apalike.bst} % could be the basis for other styles. % % The form of the \texttt{thebibliography} entries in this system is % \begin{quote} % |\bibitem[Jones et al., 1990]{jon90}...| % \end{quote} % the same as I illustrated earlier. This is the most minimal form that can % be given. I name it the \texttt{apalike} variant, after Patashnik's % \texttt{apalike.bst} and \texttt{apalike.sty}. However, there could be many % independent \texttt{.bst} files that follow this line. % % The bibliography style files belonging to this group include: % \begin{quote} % \texttt{apalike}, \texttt{apalike2}, \texttt{cea}, \texttt{cell}, % \texttt{jmb}, \texttt{phapalik}, \texttt{phppcf}, \texttt{phrmp} % \end{quote} % % \subsection{The \texttt{newapa} Style} % A major improvement has been achieved with \texttt{newapa.bst} and the % accompanying \texttt{newapa.sty} files by Stephen N. Spencer and Young U. % Ryu. Under their system, three separate items of information are included % in the |\bibitem| label, to be used as required. These are: the full % author list, the abbreviated list, and the year. This is accomplished by % means of a |\citeauthoryear| command included in the label, as % \begin{quote} % |\bibitem[\protect\citeauthoryear{Jones, Barker,|\\ % | and Williams}{Jones et al.}{1990}]{jon90}...| % \end{quote} % Actually, this only illustrates the basic structure of |\citeauthoryear|; % the \texttt{newapa} files go even further to replace some words and % punctuation % with commands. For example, the word `and' above is really % |\betweenauthors|, something that must be defined in the \texttt{.sty} file. % Of course, |\citeauthoryear| is also defined in that file. A % number of different |\cite| commands are available to print out the % citation with complete author list, with the short list, with or without % the date, the textual or parenthetical form. % % Thus the |\citeauthoryear| entry in |\bibitem| is very flexible, % permitting the style file to generate every citation form that one might % want. It is used by a number of other styles, with corresponding % \texttt{.sty} files. They all appear to have been inspired by % \texttt{newapa.bst}, although they lack the extra punctuation commands. % % Bibliographic style files belonging to the \texttt{newapa} group include % \begin{quote} % \texttt{newapa}, \texttt{chicago}, \texttt{chicagoa}, \texttt{jas99}, % \texttt{named} % \end{quote} % Note: the last of these, \texttt{named.bst}, uses |\citeauthoryear| in a % slightly different manner, with only two arguments: the short list and % year. % % \subsection{The Harvard Family} % The same effect is achieved by a different approach in the Harvard family % of bibliographic styles. Here a substitute for |\bibitem| is used, as % \begin{quote} % |\harvarditem[Jones et al.]{Jones, Baker, and|\\ % | Williams}{1990}{jon90}...| % \end{quote} % The accompanying interface package file is called \texttt{harvard.sty} % and is written by Peter Williams and Thorsten Schnier. It % defines |\harvarditem| as well as the citation commands |\cite|, for % parenthentical, and |\citeasnoun|, for textual citations. The first % citation uses the long author list, following ones the shorter list, if % it has been given in the optional argument to |\harvarditem|. % % Bibliography styles belonging to the Harvard family are % \begin{quote} % \texttt{agsm}, \texttt{dcu}, \texttt{kluwer} % \end{quote} % % This package has been updated for \LaTeXe, with many additions to % add flexibility. The result is a powerful interface that should meet most % citation needs. (It does not suppress repeated authors, though, % as \thestyle{} does.) % % \subsection{The Astronomy Style} % Apparently realizing the limitations of his \texttt{apalike} system, Oren % Patashnik went on to develop a `true' \texttt{apa} bibliographic style, % making use of the method already employed by an astronomy journal. This % is actually very similar to the \texttt{newapa} label but with only the % short list of authors: % \begin{quote} % |\bibitem[\protect\astroncite{Jones et al.}{1990}]{jon90}|\\ % | ...| % \end{quote} % It requires the package file \texttt{astron.sty} % or any other style that defines |\astroncite| appropriately. % % Bibliographic styles belonging to the astronomy group are % \begin{quote} % \texttt{apa}, \texttt{astron}, \texttt{bbs}, \texttt{cbe}, % \texttt{humanbio}, \texttt{humannat}, \texttt{jtb} % \end{quote} % % This is as good as the |\citeauthoryear| command, although not as % flexible since the full list of authors is missing. % % \subsection{The \texttt{authordate} Style} % Finally, I have also found some packages making use of a label command % called |\citename| in the form % \begin{quote} % |\bibitem[\protect\citename{Jones et al., }1990]{jon90}|\\ % | ...| % \end{quote} % % This is not a good system since the author list and date are not cleanly % separated as individual arguments, and since the punctuation is included % in the label text. It is better to keep the punctuation fully removed, as % part of the definitions in the \texttt{.sty} file, for complete flexibility. % % Bibliographic styles belonging to this group are % \begin{quote} % \texttt{authordate1}, \texttt{authordate2}, \texttt{authordate3}, % \texttt{authordate4}, \texttt{aaai-named} % \end{quote} % with accompanying style file \texttt{authordate1-4.sty}. % % \section{The \thestyle{} System} % The form of the |\bibitem| entry that I have used for all my % bibliographic styles is only slightly more complicated than the minimal % one, but allows a clean separation between authors and date: % \begin{quote} % |\bibitem[Jones et al.(1990)]{jon90}...|\\[1ex] % or alternatively\\[1ex] % |\bibitem[Jones et al.(1990)Jones, Baker, |\\ % \hspace*{2em}|and Williams]{jon90}...| % \end{quote} % % (One weakness of the \thestyle{} format is that it fails if the author % list itself contains parentheses! This may be fixed up if the author list % is grouped in curly braces.) % % I wanted to name the system something like `natural sciences bibliography', % intending it to be a variant of \texttt{natsci.sty}. Since that name % was already taken, I resorted to the rather cryptic, and definitely ugly, % \thestyle. % % The \thestyle\texttt{.sty} package\footnote{Formerly called a \emph{style % file} in the older \LaTeX~2.09 terminology.} % supports not only my own |\bibitem| format, but % also all the others described here, plus numerical citation modes. % The additional questions of citation style (type of brackets, commas or % semi-colons between citations) can be defined once and for all for each % \texttt{.bst} file and need never be specified explicitly in the source text. % The use of |\cite| is the same for all citation styles, meaning that the % additional features that might be available in the `proper' \texttt{.sty} % file will be missing. (This could be changed later.) The result is a % single \LaTeX{} package to handle {\em all\/} the bibliographic % styles in a uniform manner. % % As of version 5.1 (1994 June 22), the source file contains coding for a % \LaTeXe{} package file (the new standard) as well as that for an older % \LaTeX~2.09 style option file. The latter is extracted with the % \texttt{docstrip} option \texttt{209}. % % \begin{quote}\slshape % \textbf{New to version 6.0}: (1995 Sep 29) \\ % In previous versions, each \texttt{.bst} file was either numerical or % author--year only. Applying the wrong mode led to grotesque results, and % the mode could not always be selected automatically. With version~6.0, % all the author--year bibliographic style files can also be used for % \emph{numerical} citations, by simply selecting the mode in one of the % ways described in Sections~\ref{sec:bibpunct} and \ref{sec:opts}. It is % not possible to employ author-year citations with pure numerical % \texttt{.bst} files, and never will be. % % See Section~\ref{sec:6.0} for more information. % \end{quote} % % \section{Using this Package}\label{sec:usage} % % In this paper, I distinguish between the citation \emph{mode} (author--year % or numerical) and citation \emph{style} (the type of punctuation used for % citations). The citation style is something that is independent of the % bibliography style and is not programmed in the \texttt{.bst} files. % % \subsection{Basic Citation Commands} % % \DescribeMacro{\citet} % \DescribeMacro{\citep} % The \thestyle{} package has two basic citation commands, |\citet| and % |\citep| for \emph{textual} and \emph{parenthetical} citations, respectively. % There also exist the starred versions |\citet*| and |\citep*| that print % the full author list, and not just the abbreviated one. % All of these may take one or two optional arguments to add some text before % and after the citation. % \begin{quote} % \begin{tabular}{l@{\quad$\Rightarrow$\quad}l} % |\citet{jon90}| & Jones et al.

The presence of an empty % optional text in square brackets signaled parenthetical. This syntax has been % retained for compatibility, but is no longer encouraged. % % This means that |\cite| (without notes) is the same as |\citet| in % author--year mode, whereas in numerical mode, it is the same as |\citep|. % The starred version, as well as the one or two optional notes, may also be % used. % % \subsection{Extended Citation Commands} % % \DescribeMacro{\citealt} % As an alternative form of citation, |\citealt| is the same as |\citet| % but \emph{without any parentheses}. Multiple references and the % starred variant also exist. % \begin{quote} % \begin{tabular}{l@{\quad$\Rightarrow$\quad}l} % |\citealt{jon90}| & Jones et al. 1990\\ % |\citealt*{jon90}| & Jones, Baker, and Williams 1990\\ % |\citealt{jon90,jam91}| & Jones et al. 1990; James et al. 1991 % \end{tabular} % \end{quote} % % \DescribeMacro{\citeauthor} % \DescribeMacro{\citeyear} % \DescribeMacro{\citefullauthor} % In author--year schemes, it is sometimes desirable to be able to refer to % the authors without the year, or vice versa.

The mandatory ones are: % \begin{enumerate} % \item the opening bracket symbol, default = ( % \item the closing bracket symbol, default = ) % \item the punctuation between multiple citations, default = ; % \item the letter `n' for numerical style, or `s' for numerical superscript % style, any other letter for % author--year, default = author--year; note, it is not necessary to % specify which author--year interface is being used, for all will be % recognized; % \item the punctuation that comes between the author names and the year % (parenthetical case only), default = , % \item the punctuation that comes between years when common author lists % are suppressed (default = ,); if both authors and years are common, % the citation is printed as `1994a,b', but if a space is wanted between % the extra letters, then include the space in the argument, as |{,~}|. % \end{enumerate} % % The optional argument is the character preceding a post-note, default is a % comma. % % The |\bibpunct| command must be issued in the preamble, that is, % before |\begin{document}|. (\textbf{Note:} in versions 5.4 or earlier, this % declaration had to be given after the preamble!) % % Example~1, |\bibpunct{[}{]}{,}{a}{}{;}| changes the output of % \begin{quote} % |\citep{jon90,jon91,jam92}| % \end{quote} % into [Jones et al. 1990; 1991, James et al. 1992]. % % Example~2, |\bibpunct[;]{(}{)}{,}{a}{}{;}| changes the output of % \begin{quote} % |\citep[and references therein]{jon90}| % \end{quote} % into (Jones et al. 1990; and references therein). % % \DescribeMacro{\bibstyle@xxx} % Usually the citation style is determined by the journal % for which one is writing, and is as much a part of the bibliography style % as everything else. The \thestyle{} package allows % punctuation definitions to be directly coupled to the % |\bibliographystyle| command that must always be present when \btx{} is % used. It is this command that selects the \texttt{.bst} file; by adding such % a coupling to \thestyle{} for every \texttt{.bst} file that one might % want to use, it is not necessary to add |\bibpunct| explicitly in the % document itself, unless of course one wishes to override the preset % values. % % Such a coupling is achieved by defining a command |\bibstyle@|{\em bst}, % where {\em bst\/} stands for the name of the \texttt{.bst} file. For example, % the American Geophysical Union (AGU) demands in its publications that % citations be made with square brackets and separated by semi-colons. I % have an \texttt{agu.bst} file to accomplish most of the formatting, but such % punctuations are not included in it. Instead, \thestyle{} has the % definition % \begin{quote} % |\newcommand{\bibstyle@agu}{\bibpunct{[}{]}{;}{a}{,}{,~}}| % \end{quote} % % These style defining commands may contain more than just |\bibpunct|. % Some numerical citation scheme require even more changes. For example, % the journal \textsl{Nature} not only uses superscripted numbers for % citations, it also prints the numbers in the list of references without % the normal square brackets. To % accommodate this, \thestyle{} contains the style definition % \begin{quote}\begin{verbatim} % \newcommand{\bibstyle@nature}{\bibpunct{}{}{,}{s}{}{}% % \gdef\NAT@biblabelnum##1{##1.}} % \end{verbatim} % \end{quote} % The redefined |\NAT@biblabelnum| command specifies how the reference numbers % are to be formatted in the list of references itself. % The redefinition must be made with |\gdef|, not |\def| or % |\renewcommand|. % % The selected punctuation style and other redefinitions will not be in % effect on the first \LaTeX{} run, for they are stored to the auxiliary % file for the subsequent run. % % The user may add more such definitions of his own, to accommodate those % journals and \texttt{.bst} files that he has. He may either add them to % his local copy of \thestyle\texttt{.sty}, or better put them into a file % named \thestyle\texttt{.cfg}. This file will be read in if it exists, % adding any local configurations. Thus such configurations can survive % future updates of the package. (This is for \LaTeXe{} only.) % % \medskip % \noindent\textbf{Note:} % with version~6.0, any explicit call to |\bibpunct| has priority over the % predefined citation styles. % % \DescribeMacro{\citestyle} % A preprogrammed citation style is normally invoked by the command % |\bibliographystyle|, as described above. However, it may be that % one wants to apply a certain citation style to another bibliography % style. This may be done with |\citestyle|, given \emph{before} % |\begin{document}|. For example, to use the % \texttt{plain} bibliography style (for the list of references) with the % \textsl{Nature} style of citations (superscripts), % \begin{quote} % |\documentclass{article}|\\ % |\usepackage{|\thestyle|}|\\ % |. . . . .|\\ % |\citestyle{nature}|\\ % |\begin{document}|\\ % |\bibliographystyle{plain}|\\ % |. . . . .| % \end{quote} % % \noindent % \textbf{Note:} for versions 5.5 and later, all changes to the citation % style, including punctuation, must be made before |\begin{document}|, % which freezes the citation style. % % \subsection{Priority of Style Commands}\label{sec:priority} % The citation style (punctuation and mode) can be selected by means of the % |\bibpunct|, |\citestyle|, and predefined |\bibstyle@|\textit{bst} % commands. They can also be selected by \LaTeXe{} options % (Section~\ref{sec:opts}). What happens if there are several conflicting % selections? % % The lowest priority is assigned to the predefined |\bibstyle@|\textit{bst} % commands, since they are implicit and not obvious to the user. The % \LaTeXe{} options have the next priority. Finally, any selection by % |\bibpunct| and/or |\citestyle| overrides those of the other methods. % % \subsection{Other Formatting Options} % % \DescribeMacro{\bibsection} % The list of references normally appears as a |\section*| or |\chapter*|, % depending on the main class. If one wants to redesign one's own heading, % say as a numbered section with |\section|, then |\bibsection| may be % redefined by the user accordingly. % % \DescribeMacro{\bibfont} % The list of references is normally printed in the same font size and % style as the main body. However, it is possible to define |\bibfont| % to be font commands that are in effect within the \texttt{thebibliography} % environment. % % \DescribeMacro{\bibhang} % The list of references for author--year styles uses a hanging indentation % format: the first line of each reference is flush left, the following lines % are set with an indentation from the left margin. This indentation is 1~em % by default but may be changed by redefining (with |\setlength|) the % length parameter |\bibhang|. % % \DescribeMacro{\bibsep} % The vertical spacing between references in the list, whether author--year % or numerical, is controlled by the length |\bibsep|. If this is set to % 0~pt, there is no extra line spacing between references. The default % spacing depends on the font size selected in |\documentclass|, and is % almost a full blank line. Change this by redefining |\bibsep| with % |\setlength| command. % % \subsection{Automatic Indexing of Citations} % % (New to version 6.0; applies to \LaTeXe\ only)\\[1ex] % \DescribeMacro{\citeindextrue} % \DescribeMacro{\citeindexfalse} % If one wishes to have the citations entered in the \texttt{.idx} indexing % file, it is only necessary to issue |\citeindextrue| at any point in the % document. All following |\cite| commands, of all variations, then insert % the corresponding entry to that file. With |\citeindexfalse|, these % entries will no longer be made. % % The |\bibitem| commands in the \texttt{thebibliography} environment will % also make index entries. If this is not desired, then issue % |\citeindexfalse| before |\bibliography| or |\begin{thebibliography}|. % % Of course, |\makeindex| must also be issued in the preamble to activate % indexing, as usual. Otherwise, no indexing is done at all. % % Make sure that the document has been processed at least twice after the % last \btx\ run before running the \texttt{makeindex} program. % % \DescribeMacro{\NAT@idxtxt} % The form of the index entries is set by the internal |\NAT@idxtxt|, which % can be redefined by hackers if wanted (in the \thestyle\texttt{.cfg} file % please). By default, it prints the short author list plus date in the % current parenthesis style. % % The \thestyle\ package can also be used with the \texttt{index} package of % David~M. Jones. The order in which the packages are loaded is not % important. % % \DescribeMacro{\citeindextype} % In that package, multiple index lists may be made by means of a |\newindex| % command. For example, it may be desirable to put all the citation indexing % into a separate list. First that list must be initiated with, e.g., % \begin{quote} % |\newindex{cite}{ctx}{cnd}{List of Citations}| % \end{quote} % and then the automatic citation indexing associated with this list with the % \thestyle\ command % \begin{quote} % |\renewcommand{\citeindextype}{cite}| % \end{quote} % See the documentation for \texttt{index.sty} for details. % % \subsection{Hyper\TeX\ Compatibility} % As of version~6.4, \thestyle\ is compatible with the \texttt{hyperref} % package of Sebastian Rahtz and Yannis Haralambous, for use with % Hyper\TeX. The compatibility is of a mutual nature: both packages contain % coding that interact with that of the other. Thus the version of % \texttt{hyperref} must be more recent than 1996 Oct~8. % ^^A Update the date when it is better known, after checking with Rahtz. % % \subsection{Multiple Bibliographies in One Document}\label{sec:chapbib} % % As of version 6.4, \thestyle\ is compatible with the \texttt{chapterbib} % package of Donald Arseneau and Niel Kempson,\relax % \footnote{I have used version 1.5 from 1995/10/09; cannot guarantee % earlier versions.} % which makes it possible to have several % bibliographies in one document. The usual application is to have % bibliographies in each chapter of a book, especially if they have been % written by different authors. % % The \texttt{chapterbib} package works in a very natural way for the % author; only the editor who puts all the chapters together into one book % has to do some extra work. % % The package makes use of the |\include| command, and it is in fact every % |\include|d file that has its own bibliography. For large books, it makes % very good sense to take advantage of this feature in any case. % % To review the use of |\include|, recall that the main file % \begin{verbatim} % \documentclass{...} % \includeonly{ch2} % \begin{document} % \include{ch1} % \include{ch2} % \include{ch3} % \end{document} % \end{verbatim} % will process only the file \texttt{ch2.tex} as though the files % \texttt{ch1.tex} and \texttt{ch3.tex} were also present. That is, all % counters, especially the page and section numbers, as well as % cross-referencing definitions, will function as if the whole document % were processed. The trick is that each |\include|d file has it own % \texttt{.aux} file containing these definitions, and they are all read % in every time, even if the corresponding \texttt{.tex} file is not. The % \texttt{.aux} files also contain the citation information for \btx, % something that the \texttt{chapterbib} package exploits. % % If |\usepackage{chapterbib}| has been given, the keys in each |\cite| % and |\bibitem| command are associated with the current |\include|d file % and are distinguished from the identical key in a different file. Each of % these files must contain its own |\bibliography| and |\bibliographystyle| % commands. One processes \btx\ on each file separately before processing % it under \LaTeX\ (at least twice). % % \subsubsection{Special Considerations for \thestyle\ and % \texttt{chapterbib}} % % The order in which the \texttt{chapterbib} and \thestyle\ packages are loaded % is unimportant. % % The \texttt{chapterbib} package provides an option \texttt{sectionbib} % that puts the bibliography in a |\section*| instead of |\chapter*|, % something that makes sense if there is a bibliography in each chapter. % This option will not work when \thestyle\ is also loaded; instead, add % the option to \thestyle. (The \texttt{sectionbib} option can always be % given, but it only has meaning for the \texttt{book} and \texttt{report} % classes, or for classes derived from them.) % % Every |\include|d file (with citations) must contain its own % |\bibliography| command where the bibliography is to appear. The database % files listed as arguments to this command can be different in each file, % of course. However, what is not so obvious, is that each file must also % contain a |\bibliographystyle| command, \emph{preferably with the same % style argument}. If different bibliography styles are specified for % different files, then the preprogrammed citation style (punctuation and % citation mode) will be that of the first bibliography style given. The % preprogrammed citation styles can only be changed in the preamble (see % Section~\ref{sec:priority}), something that guarantees a uniform style % for the entire document.\relax % \footnote{It would be relatively easy to allow changes in style anywhere % in the document, but this strikes me as bad policy. However, it is % provided for with the \texttt{docstrip} option \texttt{nopreonly}.} % % \subsection{Sorting and Compressing Numerical Citations} % % Another package by Donald Arseneau, \texttt{cite.sty}, reimplements the % entire (numerical) citation system such that one can control the % punctuation and citation format, all of which is done by \thestyle\ as % well. However, it also can sort and compress numerical citations, % something that is required by some journals. % % What this means is that when multiple citations are given with a single % |\cite| command, the normal order of the numbers is in the sequence % given. This is usually a wild list of numbers, such as [4,2,8,3]. With % the \texttt{cite} package, this list becomes [2--4,8]. % % It is impossible to make the \texttt{cite} and \thestyle\ packages % compatible, since both reimplement |\cite| from scratch. Instead, I have % taken the necessary coding from \texttt{cite.sty} and modified it for % \thestyle{}. This coding becomes activated % by including the option \texttt{sort} in the |\usepackage| command. % It only affects numerical % citations, and has no influence on the author--year ones. % % \section{Numerical Citations with Author--Year Styles}\label{sec:6.0} % % (New to version 6.0)\\[1ex] % In earlier versions, each \texttt{.bst} file could be used either for % numerical or author--year citation mode, without any possibility of % switching. Obviously numerical \texttt{.bst} files can never be used for % author--year citations (the information is missing in the auxiliary file) % but there is no reason why the converse should not work. % % I have been frequently asked if I could implement this feature, and I at % first replied that it would be quite easy. That was a mistake. The % numerical information was missing in the auxiliary files, so the % |\cite| commands could never access it. % % \subsection{New Coding} % I have now recoded \thestyle{} so that the separation of author and year % information comes before the information is written to the auxiliary % file, and furthermore, a sequential number is also written. This permits % numerical citations with \emph{any} of the author--year bibliographic style % files. % % The recoding has made fewer internal changes than I expected. Any users % who have local redefinitions of my internals should be aware that of the % citation commands, only |\NAT@citexnum| has been altered. Otherwise the % changes are in the parsing commands |\NAT@parse| and |\NAT@parse@date|. % Of the external commands, |\bibitem| is completely redefined, and % |\citeauthor|, |\citeyear|, and |\citefullauthor| are different. % % Version~5.5 actually made far more internal changes: all internal % commands were renamed to conform to recommended \LaTeX{} coding % practices. % % \subsection{Selecting Numerical Mode} % By default, \thestyle{} is in author--year mode. This can be changed by % \begin{enumerate} % \item selecting a numerical bibliography style with predefined % citation style, defined either in the package or in the local % configuration file; % % \item giving options \texttt{numbers} or \texttt{super} to the % |\usepackage| command; % % \item issuing |\bibpunct| with the 4th mandatory argument set to \texttt{n} % or \texttt{s}; % % \item issuing |\citestyle| with the name of a predefined numerical % bibliography style. % \end{enumerate} % The methods are listed in order of increasing priority. % % The \thestyle{} package will automatically switch to numerical mode if % any one of the |\bibitem| entries fails to conform to the possible % author--year formats. There is no way to override this, since such an % entry would cause trouble in the author--year mode. % % There are certain special `numerical' styles, like that of the standard % \texttt{alpha.bst}, which include a non-numerical label in place of the % number, in the form % \begin{quote} |\bibitem[ABC95]{able95}| \end{quote} % As far as \thestyle\ is concerned, this label does not conform to the % author--year possibilities and is therefore considered to be numerical. % The citation mode switches to numerical, and |\cite{able95}| prints % [ABC95]. % % \subsection{New Bibliography Styles} % I provided three new \texttt{.bst} files to replace the standard \LaTeX\ % numerical ones: % \begin{quote}\ttfamily % plainnat.bst \qquad abbrvnat.bst \qquad unsrtnat.bst % \end{quote} % These produce reference lists in the same style as the corresponding % standard \texttt{.bst} file, but can only be used with \thestyle{}. The % advantage is that they can be used in both numerical and author--year % mode. % % In fact, \texttt{unsrtnat.bst} is rather silly for author--year % citations: the references are listed in the order they were cited, which % makes it difficult to find them. It is only included in case an author % wishes to switch from \texttt{plainnat} (author--year) to the unsorted % numerical mode, retaining the |\citeauthor| and |\citeyear| commands in % his paper. % % It is not possible to produce a modified version of \texttt{alpha.bst} % since it would conflict with the |\bibitem| format of \thestyle. % % The sample bibliography style file \texttt{natbib.bst} will no longer be % distributed. It merely represented a demonstration of the |\bibitem| % syntax for \thestyle, a function that is now taken over by % \texttt{plainnat.bst} and friends. % % \section{Local Configuration} % For \LaTeXe, it is possible to add a local configuration file % \thestyle\texttt{.cfg}, which is read in, if it exists, at % the end of the package. It may thus contain coding to supecede that in % the package, although its main purpose is to allow the user to add his % own |\bibstyle@|\textit{bst} definitions to couple citation punctuation % with local bibliography styles. % % \section{Options with \LaTeXe}\label{sec:opts} % One of the new features of \LaTeXe{} is \emph{options} for the packages, % in the same way as main styles (now called \emph{classes}) can take % options. This package is now installed with % \begin{quote} % |\documentclass[..]{...}|\\ % |\usepackage[|\emph{options}|]{|\thestyle|}| % \end{quote} % The options available provide another means of specifying the % punctuation for citations: % \begin{description} % \item[\ttfamily round] (default) for round parentheses; % \item[\ttfamily square] for square brackets; % \item[\ttfamily curly] for curly braces; % \item[\ttfamily angle] for angle brackets; % \item[\ttfamily colon] (default) to separate multiple citations with % colons; % \item[\ttfamily comma] to use commas as separaters; % \item[\ttfamily authoryear] (default) for author--year citations; % \item[\ttfamily numbers] for numerical citations; % \item[\ttfamily super] for superscripted numerical citations, as in % \textsl{Nature}; % \item[\ttfamily sort] puts multiple numerical citations in order and % compresses them if possible (as 3--6, 15); % \item[\ttfamily sectionbib] redefines |\thebibliography| to issue % |\section*| instead of |\chapter*|; valid only for classes with a % |\chapter| command; to be used with the \texttt{chapterbib} package. % \end{description} % % If any of these options are selected, the predefined citation styles in % the commands |\bibstyle@|\textit{bst} will be no longer be effective. % If either |\bibpunct| or |\citestyle| is given in the preamble, the above % punctuation options will no longer hold. % % \section{As Module to Journal-Specific Styles} % Although \thestyle{} is meant to be an all-purpose bibliographic style % \emph{package}, it may also be incorporated as a module to other % packages for specific journals. In this case, many of the general features may % be left off. This is allowed for with \texttt{docstrip} options that not % only leave off certain codelines, but also include extra ones. So far, % options exist for % \begin{description} % \item[\ttfamily subpack] produces a basic version with author--year only, % fixed citation punctuation, no |\bibpunct| nor |\citestyle| nor % predefined styles; % \item[\ttfamily subpack,egs] for journals of the \textsl{European Geophysical % Society}, in particular \textsl{Nonlinear Processes in Geophysics}; % \item[\ttfamily subpack,agu] for \textsl{American Geophysical Union} journals. % \end{description} % The \texttt{subpack} option must always be used with \texttt{package}. % % Previous options \texttt{jgr} and \texttt{grl} have become obsolete due % to revisions in these journals; they have been replaced by the more % general \texttt{agu} option. % % \section{Summary} % % The following summary is included as comments at the beginning of the % \thestyle\texttt{.sty} file, for quick reference. Certain lines are % dependent on the \texttt{docstrip} options. % % \iffalse %<*package&!subpack> % \fi % \begin{verbatim} % This package reimplements the LaTeX \cite command to be used for various % citation styles, both author-year and numerical.

It % appears in square braces before all other arguments. May be left off. % Example (and default) \bibpunct[,]{(}{)}{;}{a}{,}{,} % % To make this automatic for a given bib style, named newbib, say, make % a local configuration file, natbib.cfg, with the definition % \newcommand{\bibstyle@newbib}{\bibpunct...} % Then the \bibliographystyle{newbib} will cause \bibstyle@newbib to % be called on THE NEXT LATEX RUN (via the aux file). % % % Such preprogrammed definitions may be invoked in the text (preamble only) % % Such preprogrammed definitions may be invoked anywhere in the text % by calling \citestyle{newbib}. This is only useful if the style specified % differs from that in \bibliographystyle. % %<*!209> % With \citeindextrue and \citeindexfalse, one can control whether the % \cite commands make an automatic entry of the citation in the .idx % indexing file. For this, \makeindex must also be given in the preamble. % % LaTeX2e Options: (for selecting punctuation) % round - round parentheses are used (default) % square - square brackets are used [option] % curly - curly braces are used {option} % angle - angle brackets are used
