# How do I add a bibliography to my document?

First, export a `.bib` file from your reference manager, or create a `.bib` file manually. Then, upload the `.bib` file via the files menu. You can also import `.bib` files via the direct [Mendeley or Zotero integration](/latex/knowledge-base/073-how-to-link-zotero-to-your-overleaf-account.md) which is available to those on [paid plans](https://www.overleaf.com/user/subscription/plans).

Once your bibliography file has been uploaded, there are a number of bibliography packages which can be used to display the relevant entries in your document (as you cite them). As an example, we often use the `natbib` package, and the commands for `natbib` look like:

```latex
...
\usepackage{natbib}
...
\begin{document}
...
\bibliographystyle{plainnat}
\bibliography{name-of-your-bib-file-here}
\end{document}
```

You can also edit the bib file directly via the files menu. For additional information on adding a bibliography to your document, see [Part 2 of our Intro to LaTeX course](https://www.overleaf.com/blog/9) or check out the [LaTeX Wikibook](http://en.wikibooks.org/wiki/LaTeX/Bibliography_Management).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/questions-and-answers/20-how-do-i-add-a-bibliography-to-my-document.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
