# Natbib Guide

> Use natbib for author-year and numerical citations in BibTeX-based LaTeX projects.

Use `natbib` when legacy BibTeX workflows or journal templates require it.

## Basic Setup

```latex natbib-basic.tex theme={null}
\documentclass{article}
\usepackage[authoryear,round]{natbib}

\begin{document}
\citet{smith2024} reports a strong baseline.
Replications confirm this \citep{lee2025,nguyen2025}.

\bibliographystyle{plainnat}
\bibliography{references}
\end{document}
```

## Commands

* `\citet{key}` textual citation.
* `\citep{key}` parenthetical citation.
* `\citeauthor{key}` and `\citeyear{key}` for split control.
