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. (1990) || Jones et al. [21] % \citep{key} ==>> (Jones et al., 1990) || [21] % Multiple citations as normal: % \citep{key1,key2} ==>> (Jones et al., 1990; Smith, 1989) || [21,24] % or (Jones et al., 1990, 1991) || [21,24] % or (Jones et al., 1990a,b) || [21,24] % \cite{key} is the equivalent of \citet{key} in author-year mode % and of \citep{key} in numerical mode % Full author lists may be forced with \citet* or \citep*, e.g. % \citep*{key} ==>> (Jones, Baker, and Williams, 1990) % Optional notes as: % \citep[chap. 2]{key} ==>> (Jones et al., 1990, chap. 2) % \citep[e.g.,][]{key} ==>> (e.g., Jones et al., 1990) % \citep[see][pg. 34]{key}==>> (see Jones et al., 1990, pg. 34) % (Note: in standard LaTeX, only one note is allowed, after the ref. % Here, one note is like the standard, two make pre- and post-notes.) % \citealt{key} ==>> Jones et al. 1990 % \citealt*{key} ==>> Jones, Baker, and Williams 1990 % \citealp{key} ==>> Jones et al., 1990 % \citealp*{key} ==>> Jones, Baker, and Williams, 1990 % Additional citation possibilities (both author-year and numerical modes) % \citeauthor{key} ==>> Jones et al. % \citeauthor*{key} ==>> Jones, Baker, and Williams % \citeyear{key} ==>> 1990 % \citeyearpar{key} ==>> (1990) % \citetext{priv. comm.} ==>> (priv. comm.) % \citenum{key} ==>> 11 [non-superscripted] % Note: full author lists depends on whether the bib style supports them; % if not, the abbreviated list is printed even when full requested. % % For names like della Robbia at the start of a sentence, use % \Citet{dRob98} ==>> Della Robbia (1998) % \Citep{dRob98} ==>> (Della Robbia, 1998) % \Citeauthor{dRob98} ==>> Della Robbia % % % Citation aliasing is achieved with % \defcitealias{key}{text} % \citetalias{key} ==>> text % \citepalias{key} ==>> (text) % % Defining the citation mode and punctual (citation style) % \setcitestyle{<comma-separated list of keywords, same % as the package options>} % Example: \setcitestyle{square,semicolon} % Alternatively: % Use \bibpunct with 6 mandatory arguments: % 1. opening bracket for citation % 2. closing bracket % 3. citation separator (for multiple citations in one \cite) % 4. the letter n for numerical styles, s for superscripts % else anything for author-year % 5. punctuation between authors and date % 6. punctuation between years (or numbers) when common authors missing % One optional argument is the character coming before post-notes. 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.
