Should I add a DOI as well as a URL in my reference?

For all referencing styles used at Notre Dame Australia, you would use one of these "locators" for electronic resources, but never both.

Chicago Manual of Style, 17th edition and APA 7th edition

The DOI, e.g. 10.1177/0191453713494967 is appended to the prefix https://doi.org/ in order to form a URL, e.g. https://doi.org/10.1177/0191453713494967.

APA 6th

Where there is a DOI provided, the preference is to use that in the standard format doi:10.1177/0191453713494967. If no DOI is found, then include the URL instead.

See the Referencing Guides for more information and examples.
