BibTeX for LaTeX

What is natbib?

Natbib is a LaTeX package that provides greater control over how citations are created and displayed in your document. It supports various citation styles including numerical style (Vancouver) and author / date (Harvard).

Inserting citations and generating a reference list 

• Create a .bib File: compile your references in a .bib file (see Generating BibTeX file)
• Include natbib package: add \usepackage{natbib} in the preamble of your LaTeX document
• Add citations: use relevant variations of the \cite command to add in-text citations
• Specify bibliography style: choose your referencing style with \bibliographystyle{style} (see Harvard, Vancouver, IEEE)
• Generate reference list: add \bibliography{filename} at the end of your document to generate the reference list

In practice:

\documentclass{article}
\usepackage{natbib}
\begin{document}

You are citing a reference using Natbib: \citep{Unique_key}.

\bibliographystyle{agsm}
\bibliography{references}

\end{document}
