Bibliography and citation style

Bibliography Style

Citation Style

 

In LaTeX, one can use a number of different bibliography styles. This style defines the layout of the pointers in the body text (e.g. ``[1]''), as well as the layout of the reference list. For your convenience, we put here a sample output result for a few bibliography styles (look for other ones in ~texmf/bibtex/bst/*.bst). Most common are abbrv, acm, alpha, apalike, ieeetr, plain, siam and unsrt. My personal choice is using the "apalike" style.

This is how the LaTeX-source might look like:

...
\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}

Reference to a paper in proceedings [1], to an article [2], and to a book [3].

References

You can also use a bibliography style and another for citations. In this case use the \bibliographystyle just before the including the bibliography file
 

\begin{document}

...

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

\bibliography{abbr_long,pubext}
...

\end{document}
 

Citation Style

I like to use the author(year) citation style in my documents instead of the "[1]" like citations . There may be different options but I found the following very interesting.
 

The NATBIB Citation commands

The natbib package defines a number of very useful citation commands which replace the usual \cite. These are really necessary in any author-year citation system, where you don't always cite a reference using the same format for the citation. These commands and their output are illustrated below. The most frequently used are \citet (textual cite) and \citep (parenthetical cite). \cite is equivalent to \citet, but this shouldn't be used because it is often defined by other style files.

\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; ...)

You can use optional arguments to get text before and after the citation(s):

\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)

\citet*{KEY}

Bester, Winters, & Alexander (1998)

\citeauthor{KEY}

Bester et al.

\citeyear{KEY}

1998

\citeyearpar{KEY}

(1998)

\citealt{KEY}

Bester et al. 1998

Options for NATBIB

usepackage[options]{natbib}
 

round

(default) for round parentheses;

square

for square brackets;

curly

for curly braces;

angle

for angle brackets;

colon

(default) to separate multiple citations with colons;

comma

to use commas as separators;

authoryear

(default) for author­year citations;

numbers

for numerical citations;

super

for superscripted numerical citations, as in Nature;

sort

orders multiple citations into the sequence in which they appear in the list of references;

sort&compress as sort but in addition multiple numerical citations are compressed if possible (as 3­6, 15);

longnamesfirst makes the first citation of any reference the equivalent of the starred variant (full author list) and subsequent citations normal (abbreviated list);
 

Usage

Just include the package natbib with the proper options before \begin{document} like
 

\documentclass[11pt]{psuthesis}
.....
%% optional packages, in case you want AMS math macros and AMS symbols

\usepackage[comma,authoryear]{natbib} %% Here goes the natbib declaration ( Other options can be given)
....
 

\begin{document}

...

citet{KEY}

%% Citatitions

\citep{KEY}

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

\bibliography{abbr_long,pubext}
...

\end{document}
