The contributors are set as ‘bibliographic’ by default.

By un-ticking the checkbox in the ‘Bibliographic Contributor’ field on a contributor’s permissions setting, you can make the contributor ‘non-bibliographic’.

Although non-bibliographic contributors can access a project, they will not be displayed on the project’s main screen, components management page and contributor list of the Citation pane on the project main page.

You can use this function for those who help the management of a project but do not hold the copyright to the project.
