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.) % Note: full author lists depends on whether the bib style supports them; %      if not, the abbreviated list is printed even when full requested. % % Defining the citation style of a given bib style: % Use \bibpunct (in the preamble only) 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 in the text (preamble only) % 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. % % 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 %  colon  -  multiple citations separated by colon (default) %  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 %  longnamesfirst  -  makes first citation full author list %  sectionbib - puts bibliography in a \section* instead of \chapter* % Punctuation so selected dominates over any predefined ones. % LaTeX2e 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. %--- \@ifclassloaded{aguplus}{\PackageError{natbib} {The aguplus class already includes natbib coding,\MessageBreak so you should not add it explicitly} {Type  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  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  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.
