# The 'owner' field

JabRef can optionally mark all new entries added or imported to a library with your username.

You can disable or enable this feature by entering **File → Preferences → General → Entry Owner**, and selecting/deselecting the line *'mark new entries with owner name'*. You can also change the name used to mark entries. By default, your user name is used. Finally, if an entry with an existing field '*owner*' is imported, the field is updated with your name if *'Overwrite'* is checked.

The owner name is added in a field called *'owner'*, which by default is visible in the **General fields** tab in the [entry editor](https://docs.jabref.org/advanced/entryeditor).
