# Adding a citation

Citation provides information regarding the source of the data. A PDF copy of each paper should be available through Mendeley.

1. Select one of the starred papers from your project's Mendeley folder.
2. The data to be entered should be specified in the notes associated

   with the paper in Mendeley
3. Identify (highlight or underline) the data (means and statistics)

   that you will enter
4. Enter citation information 
   * [Data entry form](https://www.betydb.org/citations/new) for a new

       site: `BETYdb` → `Citations` → `new`
   * **Author**: Input the first author’s last name only
   * **Year**: Input the year the paper was published, not submitted, reviewed,

      or anything else
   * Fill out Title, Journal, Vol, & Pg. For unknown information, input 'NA'
   * **DOI**: The 'digital object identifier'. If DOI is available, PDF and

      URL are optional. This can be located in the article or in the

      article website. Use Ctrl+F 'DOI' to find it. Some older

      articles do not have a DOI.

      When entering the DOI, don't include a "doi:" prefix; the DOI should start with "10.".
   * **URL**: Web address of the article, preferably from publisher's website.  Include the "http\://" or "https\://" prefix.  If no on-line version is available, but some other information about how to obtain the citation is available, you may use a parenthesized note in lieu of a bona fide URL, e.g. "(e-mail Dr. No at <no@example.com> for a written copy)".
   * **PDF**: URL of the PDF of the article.    Include the "http\://" or "https\://" prefix.  (A parenthesized note is allowed here as well.)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://pecan.gitbook.io/betydbdoc-dataentry/entering-meta-data/adding-a-citation.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.
