Choosing a BibTeX Style

The great feature of BibTeX is that it takes a standardized database of books, articles, and other bibliographic entries and puts it in a customized format. A BibTeX style can change how a work is cited and how the bibliography is formatted. For more about using BibTeX than is described here, read our BibTeX documentation.

How to Use a Specific Style

  1. Choose your BibTeX style from the list below. Place it in the same folder as your LaTeX document.
  2. Change the \bibliographystyle line of your LaTeX document to reflect the style you chose. Remember to remove the file extension. For example, if you wanted to use the American Anthropologist style, \bibliographystyle{ filename} would become \bibliographystyle{humannat}.
  3. Many BibTeX styles require the inclusion of a package at the top of the document. The comments about a style will tell you exactly how to include its package. To learn more about your specific style, open up the .bst in your LaTeX editor or read the readme file, if available.
  4. Anytime you want to cite a document, type \cite[ pagenumber]{ citekey}. The square brackets and page number are optional. Some BibTeX styles use non-standard citations. Such styles include citation directions within the .bst itself or an included readme file.
  5. You will need to typeset your document four times, first LaTeX, BibTeX, LaTeX, and then LaTeX again. Your bibliography will now appear in the style of your choice and your citations will be correctly formatted. If question marks appear where citations should, that means you need to LaTeX your document once more. If the citations are entirely missing, you have likely forgotten to BibTeX your document.

The Seven Standard Styles

Every computer with LaTeX comes with the following seven standard styles. While they work, we recommend the natbib interpretations below. NatBib is a citation package that standardizes citation commands across many different bibliography styles, so you can switch from using plain.bst to acm.bst without having to change your in-text citations.

Styles Recommended by Reed

The following two styles were created or modified by Reed to match the following style manuals as closely as possible. Right-click (Control-Click on a Mac) on the linked name to download the style you want.

APA Style (American Psychology Association)
This is a custom style created by Ben Salzberg to duplicate the APA style as closely as possible. Make sure to include natbib as a package or it won't work. The following line should appear in the preamble: \usepackage{natbib}. 
Modern Language Associate Style (MLA)

This is a custom style created by Ben Salzberg to duplicate the Modern Language Associate style manual (6th Edition) as closely as possible. Make sure to include natbib as a package or it won't work. The following line should appear in the preamble: \usepackage{natbib}. MLA asks for citations of the form (LastName PageNumber), which is unsupported by Natbib's citation styles. We have asked Dr. Patrick Daly to provide support for these type of parenthetical citations in his next revision of natbib. In the meantime, citations of the following form will provide the correct citation:

(\citeauthor*{citekey} pagenumber)

Citation Commands Within Natbib

Author Name Styles look like this:

Numerical Styles look like this:

For additional modifications not covered above, this is a great NatBib reference sheet put out by a physical science professor in France.

And this one too! - This reference sheet includes instructions on how to change (Jones 1990, 341) to (Jones 1990: 341) [or (Jones, 1990: 341) to (Jones 1990: 341)] using the \setcitestyle command

You will see that your urls are formatted in typewritter font. If you want to change the font of your urls, add the command \urlstyle{same} to your preamble to make them the same font as the body of your paper.

Biblatex-Chicago Style

To use biblatex-Chicago, you need to change the backend from "bibtex" to "biber." To do this, pull up the preferences window (TeXShop/Preferences... or "⌘,"). Go to the "Engine" tab and change the entry in the BibTeX Engine field to "biber." This does require a somewhat new-ish version of tex, so if it's not working and you have an old version, you may need to download a new one.

Chicago A (footnotes)

To use Chicago style citations, comment out or remove the following line from the preamble:

To use Chicago A (footnote style citations), add these lines to the preamble (where "thesis" should be changed to the title of your .bib file):

Then go to the end of the .tex file and remove the following lines:

And replace them with this line:

Chicago B (parenthetical in-line citations)

To use Chicago style citations, comment out or remove the following line from the preamble:

To use Chicago B (parenthetical in-line citations), add these lines to the preamble (where "thesis" should be changed to the title of your .bib file):
\usepackage[authordate,autocite=inline,backend=biber, natbib]{biblatex-chicago}

Then go to the end of the .tex file and remove the following lines:

And replace them with this line:

In order to have the author and year all in parenthesis, use \autocite for in-text citation. If you want only the year in parenthesis, use \citet instead. 

Explore the Biblatex-Chicago readme on CTAN to find customizations.

Styles Available at is the official LaTeX archive containing both the official LaTeX packages and items contributed by LaTeX users. Many of these BibTeX styles have either been created by journal editors or publishers for their authors or by users creating packages to fulfill a personal need. One problem with the user-contributed styles is that they may not match the official style they claim to implement exactly. However, the journal-specific styles will exactly match the journal's house style, as they were designed by the journals. Therefore, we recommend testing any non-journal style by using it with a large BibTeX database and compare the resulting bibliography to the official style.

When it comes to bibliography management in LaTeX the program natbib is an alternative used in several journals. The program is not actively developed, but is very stable and widely used. This article explains how to use natbib to format and cite bibliographic sources.

Note: If you are starting from scratch it's recommended to use biblatex since that package provides localization in several languages, it's actively developed and makes bibliography management easier and more flexible.


A minimal working example is presented below:

\documentclass{article}\usepackage[utf8]{inputenc}\usepackage[english]{babel}   \usepackage{natbib}\bibliographystyle{unsrtnat}   \title{Bibliography management: \texttt{natbib} package}\author{Share\LaTeX}\date{}   \begin{document}   \maketitle   This document is an example of \texttt{natbib} package using in bibliography management. Three items are cited: \textit{The \LaTeX\ Companion} book \cite{latexcompanion}, the Einstein journal paper \cite{einstein}, and the Donald Knuth's website \cite{knuthwebsite}. The \LaTeX\ related items are \cite{latexcompanion,knuthwebsite}.   \medskip   \bibliography{sample}   \end{document}

In this example there are four basic commands to manage the bibliography:

Imports the package natbib.
Sets the bibliography style unsrtnat. See the article about bibliography styles for more information.
Prints a reference to the citation entry, what is printed depends on the citation style. The word inside the braces corresponds to a particular entry in the bibliography file.
Imports the file sample.bib that contains bibliography sources. See the bibliography file section.

[edit]Basic usage

A simple working example was shown at the introduction, there are more bibliography-related commands available.

\documentclass{article}\usepackage[utf8]{inputenc}\usepackage[english]{babel}   \usepackage[square,numbers]{natbib}\bibliographystyle{abbrvnat}   \title{Bibliography management: \texttt{natbib} package}\author{Share\LaTeX}\date{}   \begin{document}   \maketitle   This document is an example of \texttt{natbib} package using in bibliography management. Three items are cited: \textit{The \LaTeX\ Companion} book \cite{latexcompanion}, the Einstein journal paper \citet{einstein}, and the Donald Knuth's website \cite{knuthwebsite}. The \LaTeX\ related items are \cite{latexcompanion,knuthwebsite}.   \medskip   \bibliography{sample}   \end{document}

There are a few changes in this example:

  • The options and in enable squared brackets and numeric citations respectively. See the reference guide for a list of package options
  • The command adds the name of the author to the citation mark, regardless of the citation style.

[edit]The bibliography file

The bibliography files must have the standard bibtex syntax and the extension .bib. They contain a list of bibliography sources and several fields with information about each entry.

This file contains records in a special format, for instance, the first bibliographic reference is defined by:

This is the first line of a record entry, tells BibTeX that the information stored here is about an article. The information about this entry is enclosed within braces. Besides the entry types shown in the example (, and there are a lot more, see the reference guide.
The label is assigned to this entry, is a unique identifier that can be used to refer this article within the document.
This is the first field in the bibliography entry, indicates that the author of this article is Albert Einstein. Several comma-separated fields can be added using the same syntax , for instance: title, pages, year, URL, etc. See the reference guide for a list of possible fields.

The information in this file can later be printed and referenced within a LaTeX document, as shown in the previous sections, with the command . Not all the information in the .bib file will be displayed, it depends on the bibliography style set in the document.

[edit]Adding the bibliography in the table of contents

If you want the bibliography to be included in the table of contents, importing the package tocbibind in the preamble will do the trick:

\documentclass[a4paper,10pt]{article}\usepackage[utf8]{inputenc}\usepackage[english]{babel}   \usepackage[nottoc]{tocbibind}   \begin{document}   \tableofcontents   \section{First Section} This document ...   \bibliographystyle{unsrt}\bibliography{sample}   \end{document}

Adding the line

to the preamble will print the "References" or "Bibliography" in the table of contents, depending on the document type. Be careful, it will also add other elements like the Index, Glossary and list of Listings to the table of contents. For more information see the tocbibind package documentation.
