# How to reorder / sort references alphabetically or by date/year?

In the web view, references are automatically sorted based on where they appear in the document. However, **you can customize how your references are sorted in the export document** by following these steps. 

1. In the toolbar, select **Export** -> **Export Options**

2. Pick a citation style which sorts references alphabetically or by date. You have many options! You can consult [the full list](https://www.zotero.org/styles) to pick the citation/reference style that best suits your needs. Here's some handy examples:
    * **APA** (American Psychological Association 6th edition) will sort references by first author's last name 
    * **plainyr** will sort references chronologically (oldest first)

3. Click **Save** and export your document to PDF. Your references should now be sorted in the exported document.

|| Note: if you are using a custom vendor style upon export, the references will be sorted according to the vendor style settings.
