It accepts BibTeX % output intended for many other packages, and therefore acts as a % general, all-purpose citation-style interface. % % With standard numerical .bst files, only numerical citations are % possible. With an author-year .bst file, both numerical and % author-year citations are possible. % % If author-year citations are selected, \bibitem must have one of the %   following forms: %   \bibitem[Jones et al.(1990)]{key}... %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}... %   \bibitem[Jones et al., 1990]{key}... %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones %       et al.}{1990}]{key}... %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}... %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}... %   \bibitem[\protect\citename{Jones et al., }1990]{key}... %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}... % % This is either to be made up manually, or to be generated by an % appropriate .bst file with BibTeX. %                            Author-year mode     ||   Numerical mode % Then, \citet{key}  ==>>  Jones et al.

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 anywhere in the text %  by calling \citestyle{newbib}. This is only useful if the style specified %  differs from that in \bibliographystyle. % % 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. % % Package 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    <option> %   semicolon  -  multiple citations separated by semi-colon (default) %   colon  - same as semicolon, an earlier confusion %   comma  -  separated by comma %   authoryear - selects author-year citations (default) %   numbers-  selects numerical citations %   super  -  numerical citations as superscripts %   sort   -  sorts multiple citations according to order in ref. list %   sort&compress   -  like sort, but also compresses numerical citations %   compress - compresses without sorting %   longnamesfirst  -  makes first citation full author list %   sectionbib - puts bibliography in a \section* instead of \chapter* %   merge - allows the citation key to have a * prefix, %           signifying to merge its reference with that of the previous citation. %   elide - if references are merged, repeated portions of later ones may be removed. %   mcite - recognizes and ignores the * prefix for merging. % Punctuation so selected dominates over any predefined ones. % Package options are called as, e.g. %        \usepackage[square,comma]{natbib} % LaTeX the source file natbib.dtx to obtain more details % or the file natnotes.tex for a brief reference sheet. %-----------------------------------------------------------\providecommand\@ifxundefined[1]{% \ifx#1\@undefined\expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi}%\providecommand\@ifnum[1]{% \ifnum#1\expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi}%\providecommand\@ifx[1]{% \ifx#1\expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi}%\providecommand\appdef[2]{% \toks@\expandafter{#1}\@temptokena{#2}% \edef#1{\the\toks@\the\@temptokena}%}%\@ifclassloaded{agu2001}{\PackageError{natbib}  {The agu2001 class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{}\@ifclassloaded{agutex}{\PackageError{natbib}  {The AGUTeX class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{}\@ifclassloaded{aguplus}{\PackageError{natbib}  {The aguplus class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{}\@ifclassloaded{nlinproc}{\PackageError{natbib}  {The nlinproc class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{}\@ifclassloaded{egs}{\PackageError{natbib}  {The egs class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{}\@ifclassloaded{egu}{\PackageError{natbib}  {The egu class already includes natbib coding,\MessageBreak   so you should not add it explicitly}  {Type <Return> for now, but then later remove\MessageBreak   the command \protect\usepackage{natbib} from the document}  \endinput}{} % Define citation punctuation for some author-year styles % One may add and delete at this point % Or put additions into local configuration file natbib.cfg\newcommand\bibstyle@chicago{\bibpunct{(}{)}{;}{a}{,}{,}}\newcommand\bibstyle@named{\bibpunct{[}{]}{;}{a}{,}{,}}\newcommand\bibstyle@agu{\bibpunct{[}{]}{;}{a}{,}{,~}}%Amer.
