參考文獻預設樣式\bibliographystyle{plain}預設引用格式\cite，但是樣式是[1]，而不是author，有一些巨集包可以用來設定author樣式的引用。

bibliographystyle

\bibliographystyle可以用來設定參考文獻標號及參考文獻列表的樣式，常用的style有 abbrv, acm, alpha, apalike, ieeetr, plain, siam, unsrt
使用方式為

\bibliographystyle{ieeetr}  
% or: plain,unsrt,alpha,abbrv,acm,apalike,...
 

...
\begin{document}
...
Reference to a paper in 
proceedings \cite{fanty:icassp93}, 
to an article \cite{linde:tcom80}, 
and to a book \cite{abut:book90}.
...
\bibliography{abbr_long,pubext} 
% expansion macro's + entries from pubext.bib
...
\end{document}

使用效果如下

citation style

citation style 用來設定正文中的標號樣式。

natbib引用命令

常用的natbib命令有\citet(textual cite)和\citep(parenthetical cite)，\cite相當於\citet，但是最好不要用，因為通常用於定義其他格式的引用。
引用效果如下

\citet{KEY}
Bester et al. (1998)
\citep{KEY}
(Bester et al. 1998)

\citep{KEY1, KEY2, KEY3, KEY4, ...}
(Bester et al. 1998; Garibaldi et al. 1997, 1998a,b; ...)

\citep[hereafter B98]{KEY}
(Bester et al. 1998, hereafter B98)
\citep[e.g.,][]{KEY}
(e.g., Bester et al. 1998)
\citep[see][p. 68]{KEY}
(see Bester et al. 1998, p. 68)

使用*可以獲得全部的作者名稱

\citet*{KEY}
Bester, Winters, & Alexander (1998)

\citeauthor{KEY}
Bester et al.
\citeyear{KEY}
1998
\citeyearpar{KEY}
(1998)

\citetext可以用於強制在引用周圍放置文字

natbib的選項

round---(預設) 圓括號
square---方括號
curly---卷括號
angle---尖括號
colon---（預設）用冒號分隔開多個引用
